Folding Bikes - Are Dahons really that bad?

I have a Brompton which I bought about 2 months ago. I LOVE it and use it almost every day. For me, small fold was important because I plan to take it occasionally on small buses and subways. Anyway, I have been enjoying riding so much that my partner decided he'd like to get a new bike so we could ride together on weekends. I thought it would be great if he had a folder too, because we'd be much more likely to go on rides if it meant we didn't have to go through the hassle and time it takes to attach a bike rack to the car and attach the bikes to the rack, etc., etc. but if we could rather just put the folded bikes in the car trunk whenever we felt like going somewhere for a bike ride. The thing is that really small fold is not so important for him, as he will not be taking it on buses and subways. It just has to be small enough to fit in the trunk along with my Brompton. Of course, quality of ride is important too, as well as the ease of folding. He would also like to keep spending substantially lower than what I paid for the Brompton.

So, anyway, today we visited a bike shop to check out Downtubes. We test rode 3 models - all 9 speeds, 1 with derailleur, 1 with derailleur and suspension, and 1 with hub. The range of speeds on the model with the hub was ridiculous to me - the low gear no where near as low as I'd like for climbing hills, and the high way higher than he'd ever need. The range of gears on the models with the derailleur, on the other hand, seemed perfect. The ride on all three was fine, but nothing outstanding. I felt sort of stiff riding it, and didn't love the handlebars with the ends sticking up. But overall, it was fine. The fold, on the other hand, was just plain clumsy, and when folded it doesn't stay folded (unless you tie it with a bungy). That didn't impress Brompton-owning me, and it really turned my partner off.

So, we were about the leave the store when the owner suggested we try out the Dahon, which I hadn't noticed. I've read and heard a lot about the Dahons, and had even put the Curve on my short list when I was shopping for my folder, but I never actually tried one out. The model they had was a Speed 7. My partner tried it out first. He was much more pleased with the folding - smaller, more elegant, and stays together, and he liked the ride, although honestly he didn't feel a great difference between it and the Downtubes we had tried. But when I took it for a ride I had a much stronger reaction. This bike felt smooth to ride, and I *enjoyed* riding it. I can't really explain exactly why, but I felt the riding position to be more natural and pleasurable, and less "upright/stiff" than the Downtube. I really enjoyed riding it. It had that fun-factor I get from riding my Brompton.

So, here's the dilemma. Of all the folding bikes I've read and heard about, the Dahon's are the ones that I associate with the most negative comments I've come across in terms of quality. Now I'm left wondering, are there quality issues that turn up after a certain amount of riding? Do all those negative comments I've come across apply to current models of Dahons? To all models? I recently brought my Brompton into an extremely high-end bike store to have a second chainring added (granny gears), and while chatting with one of the workers about shopping for a second folder for my partner he warned me to stay away from Dahons - told me how some Dahon owner had come in for some work on his bike, and how terrible and shabby they thought it was (they sell the Tikit, but he was not trying to sell me one - we were both clear it was not in our price range - he recommended a look at the Swift, which they don't sell).

So, my question - what's the story about Dahons? I don't want to steer my partner to get a shabby bike that won't hold up. I plan to take my partner to try out a Swift, but after that I can't think of any other less expensive folders that he should consider. Perhaps some of you may have some suggestions?

Dahons are very nice bikes, but they do require regular maintenance for some fiddly bits, most notably the handlepost hinge and latch, and to a lesser extent the frame hinge and latch. It is important that you learn how to adjust these things to avoid regular trips to the LBS.

Other things are not particular of Dahons but still should be learnt to adjust, such as derailers for optimum shifting, and brakes.

Dahon has AFAIK a policy that each bike before it leaves the shop must be given a good tune-up by the shop owner. In this regard it helps a lot to choose a shop owner who actually knows how these bikes work. There are a number of these shops, Bfold, Thor (Brakemeister on this forum) and J Gaerlan who are some of the most highly praised Dahon sellers.

So no, Dahons are not really terrible, if they were they wouldn't be able to stay in business. Dahons offer good value and quality but keep a very very sharp eye on those hinge latches that everything is always nice and tight with NO play, or you may end up where you don't want to be. Other than that, if the Dahon appeals, go for it.

So, here's the dilemma. Of all the folding bikes I've read and heard about, the Dahon's are the ones that I associate with the most negative comments I've come across in terms of quality. Now I'm left wondering, are there quality issues that turn up after a certain amount of riding? Do all those negative comments I've come across apply to current models of Dahons? To all models?

So, my question - what's the story about Dahons? I don't want to steer my partner to get a shabby bike that won't hold up. I plan to take my partner to try out a Swift, but after that I can't think of any other less expensive folders that he should consider. Perhaps some of you may have some suggestions?

I think the Swift is a fine bike and probably more durable than either a Dahon or Brompton.

The problem with Dahon is they make folders costing over 1K and others just barely over $200.00 dollars! As you can imagine, the bikes costing 1K have much better quality with good components. However, Dahon still gets trashed because their bargain bikes are the ones that sell the most and they tend to have issues with quality.

Another problem with Dahon tends to be with the handlebar which are flexy and the seat post that slide down. However, the seat post issue can be resolved but the handlebar requires you to not ride out of the saddle. Another problem with Dahon are the lack of special parts once the bike is older than five years. However, you can always get parts, just not the ones that came with the bike.

Personally, many bike shops try to sell the higher end Bromptons and Bike Fridays and will only push the Dahon if they think you can't afford the more expensive brands. Like you discovered, the Dahon is well made and I like the ride. The Dahon 20' inch models are actually faster than the Brompton because the frame has no suspension. I tested the Curve SL today and found that bike is faster at accleration than the Brompton.

Tell your partner to get the Dahon Speed P8. I had that bike in a 7 Speed and regret selling it for a song. Trust me, that bike is actually faster than your Brompton but yours is probably more comfortable. The only Dahon I would avoid getting is the Espresso becuase the frame flexes too much and overall quality suffers to keep the price down.

Just tell your partner not to stand on the pedals and put too much weight on the handlebars. If he rides it and not abuses the bike it should last for years.

Hi Steve,

I was wondering if you could tell us how to cure the seatpost slippage issue ? Mine is sinking like the titanic - 5mm after 10-15 of light riding.

By the way, my wife and I tried a couple of Bromptons today, my impression ? No fun factor whatsoever, this bike is nothing but business and not in a good way, it folds fairly small but the ride quality is pretty bad, shifters and brakes are just old school, the brakes didn't work well at all and the S handle post with the flat handle bar is too low and cannot be adjusted. If I were to make a decision on a $1100 bike it would be the Mu SL no doubt.

The higher end Dahons are very good. I have just bought a Mu SL and it is an excellent ride.

make that 2
and i know of several people in town with a Mu SL as well

for the seat post, like any other bike with a fast release clip, you just need to adjust the tension of the clip every now and then.

for the handle post, as mentioned above, you'll also need to perform minor maintenance to adjust it and keep it tight.

if you are not comfortable with a wrench / screw drivers / and hex keys... then just take it to your LBS.

It was the first thing I had tried. No matter how tight the QR clamp is, it still slips, I have used both hands with a lot of force... and guess what ? it slips. 3 bike mechanics couldn't fix it. The frame could be defective, I don't know... anyhow I will be getting another Dahon after trying a Brommie earlier today and didn't feel the passion to ride it. It really feels like it was designed in the mid 60's... very poor ride compare to the Mu IMO.

I love my Dahons. They are as nice a bike as any non-folder you might get in the same price range. They have a basic folding design that has been tested by many years in production and thousands and thousands of Dahon riders. They have a tight fold compared to anything else under a grand.

I tried a Downtube based on the oft-repeated "bang for the buck" and didn't get the bang part at all. Test riding like you did is definitely the way to pick the best bike for your needs:thumb:.

i've got a speed pro 07, had it a year and its excellent. Can cover 18 miles over one hour no problem. Wheels have survived nasty potholes, i'm not too heavy and sometimes do ride out of the saddle but i keep most of my weight on the pedals (i'm slightly wary of the handlepost latch). The stelvio tyres are great, the other day noticed a hole in the back one 3mm wide and about 4mm deep (!) still no puncture! Plugged the hole with silicon sealant. I sold my old claud butler for £140, got the pro new for £620 so a £750 bike only 'really' cost me £480! I'll deffo get another Dahon in the future.

I have 3 Dahons. All reliable. They all ride like proper bikes, not some circus toy.

I suspect the real reason that you come across so much criticism of Dahons is simply because they sell more folders than anyone else.

They like to innovate, and occasionally make a turkey, but my impression is that the majority of complaints come from people who haven't bought through a bike shop, so they are buying a bike that is not properly setup in the first place.

One problem with folders is that they do have special requirements for maintenance. There has to be compromises to make a bike fold. They require intelligent maintenance and if they don't get it, they become problems.

Dahon has AFAIK a policy that each bike before it leaves the shop must be given a good tune-up by the shop owner.

I'd strongly recommend dealing with a LBS who sells Dahons. My bike wasn't properly set up and most of my intial problems have stemmed from that.

For your partners needs, I would be inclined to recommend a 20" wheel bike. I have the 16" Curve D3 and I find it impossible to get the bike to be comfy over longer distances (8 miles and more). I have a sprung brooks saddle and eargon grips to improve the ride but I think the geomentry is simply more suited to short (5 miles) distance? The other thing I would be inclined to do is to go for tried and tested designs with lots of standard parts as all these things will give you less problems over the longer term. Steel bikes are also meant to give a more comfy ride as they transfer less of the roads vibrations into the rider

I love my Dahon. Had same issues mentioned above: seatpost slippage, frame hinge.
Plus some that aren't Dahon-specific: off-center wheel, squeaky brake, misadjusted shifter.

That said, I'm surprised you didn't like the DT Mini.

I have mixed feelings about Dahons.

The good things are that they have a pretty good fold, the company updates models every year, and they cover a wide range of bike types and prices. They've gotten better at making the bikes a little more adjustable.

The bad things are that they tend to have some proprietary parts, which a few years down the line can be hard to replace if they break; and the handleposts tend to be very flexy. So it's a bad plan to pull back on the bars, especially when climbing.

IMO they're very good for some tasks, especially commuting and general riding. If you think you will ride 100+ miles a week, I'd opt for something a little more solid.

One caveat on the impressions of negative comments.... Dahon is by far the largest maker of folding bikes, so in general you're likely to hear more comments (good and bad) about them than any other maker.

Joose, can you elaborate on what's uncomfortable? I still find my 20" Dahon too harsh, but not excessively so unless the road surface is really bad (with Big Apple tyres). The geometry is good, the saddle-to-handlebar length fits me just right with the saddle almost fully back in the post clamp. Are you not able to stretch forward enough on the mini?

Thanks everyone for all your responses. It appears that there are four areas of concern

1) frame hinge
2) handlebar hinge/latch
3) proprietary parts
4) seatpost slipage

1) FRAME HINGE - is this just a matter of tightening the thumbscrew so when you close the latch it closes tighter? I don't quite understand why this is being cited as a particular Dahon problem - I mean, don't all latches work the same way (eg. the latch that I open and close to raise and lower the seat on my Brompton). This latch on my Brompton hasn't required tigthtening after 2 months of use, and I think if it ever did it would be obvious because the latch would feel loose when I closed the latch. I would think all such latches would have the same tendency to go loose over time and tightening the thumbscrew is so easy I would not consider it a problem unless it happened with great frequency. Why is the Dahon especially problematic?

2) HANDLEBAR HINGE/LATCH - If I couldn't stand up on my Brompton pedals and pull up or put weight on my handlebars I think I would consider that a serious limitation. Again, is the latch on the Dahon designed differently from others?

3) PROPRIETARY PARTS - I'll put that on my "to consider" list. From what I've read the Xootr Swift does not use a lot of proprietary parts - something we'll take into account when we test ride it.

4) SEATPOST SLIPAGE - This worries me, too. It seems some (most?) avoid/fix this by simply tightening the latch, but apparently others have had no luck fixing this problem. If it is unfixable would that be covered by warranty? I would consider that a serious flaw and would want a replacement bike if it truly could not be cured by simple latch tightening.

Boeshield T-9 is a solvated parafin wax lubricant. Used sparingly on the seatpost should prevent the seatpost from slipping.

My swift seatpost slid down when I first got it. T-9 has stopped this from happening. It also works well as a chain lubricant/cleaner

Firstly let me describe myself.

I'm 30, male, reasonably fit, 5'10, 14 stones. I'm heavy for my height because I'm broad not fat.

To improve my comfit on the Curve I have:


Fitted GR2 Ergon grips to reduce vibration which was making my palms and wrists ache. Also, fitting them allows me to hold the barends for a change of position. (http://www.ergon-bike.com/en/grips/gr2.html)

I also wear bikehut extreme gloves which have heavy padding for shock absorbtion. (http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_235519_langId_-1_CarSelectorCatalogId__CarSelectorGroupId__varient__categoryId_103718_crumb_33980-76809_parentcategoryrn_103718)

My seat has been upgraded twice. Once from a style I use to use on my hybrid bike (£45), then realised I was not stretched out enough for it to work so changed it to a Brooks Sprung Flyer, which is set as far back as possible.(http://www.brooksengland.com/shop/shopProductDetail.aspx?id=uid-20070521.173925.578.1250-14-00145E457A63------------------42)

My tires are at the maximum PSI which I will lower the pressure soon, I just wanted to try them out at this pressure first.

These are all the things I have done to the bike to improve the ride.

However, my real problems are.. and which I don't think I can solve.

If I extend the seat post fully out for my legs, I'm really hunched over in a short space which hurts my wrists and give me quite bad backache.

If I lower the seat enough for that to stop, my legs and knees hurt and my wrists still hurt.

My handlebars are as high as they can go.

For short distances, for me personally up to 5 miles its fine, over that is where I get the problems.

I want to say that these problems are mine and don't mean that others would notice anything? The other thing to say is that I believe personally I chose the wrong size bike and I would of been better on a 20" bike so that I could of stretched out more.

Hindsight is a wonderful thing :p In my defence, I was not expecting to travel the full distance home each night from work (9 miles) but I'm enjoying cycling again so much!!! :love:

So for me (I speak for no others) I would now choose a 20" bike so that I could stretch out more (or perhaps a Mezzo as they seem to be wide?), I would choose steel so less vibration came through the frame. Otherwise, If I was to stick to my original plan (which was to travel halfway to work on the train and halfway back for some good exercise) I would choose a Strida as I believe it would be fine upto the 5 miles I do by travelling on the train and when on the train I would have the minimum of fuss with it.

......The thing is that really small fold is not so important for him, as he will not be taking it on buses and subways. It just has to be small enough to fit in the trunk along with my Brompton. Of course, quality of ride is important too, as well as the ease of folding. He would also like to keep spending substantially lower than what I paid for the Brompton.....So, we were about the leave the store when the owner suggested we try out the Dahon, which I hadn't noticed. I've read and heard a lot about the Dahons, and had even put the Curve on my short list when I was shopping for my folder, but I never actually tried one out. The model they had was a Speed 7. My partner tried it out first. He was much more pleased with the folding - smaller, more elegant, and stays together, and he liked the ride, although honestly he didn't feel a great difference between it and the Downtubes we had tried. But when I took it for a ride I had a much stronger reaction. This bike felt smooth to ride, and I *enjoyed* riding it. I can't really explain exactly why, but I felt the riding position to be more natural and pleasurable, and less "upright/stiff" than the Downtube. I really enjoyed riding it. It had that fun-factor I get from riding my Brompton.

So, here's the dilemma. Of all the folding bikes I've read and heard about, the Dahon's are the ones that I associate with the most negative comments I've come across in terms of quality. Now I'm left wondering, are there quality issues that turn up after a certain amount of riding? Do all those negative comments I've come across apply to current models of Dahons? To all models? I recently brought my Brompton into an extremely high-end bike store to have a second chainring added (granny gears), and while chatting with one of the workers about shopping for a second folder for my partner he warned me to stay away from Dahons - told me how some Dahon owner had come in for some work on his bike, and how terrible and shabby they thought it was (they sell the Tikit, but he was not trying to sell me one - we were both clear it was not in our price range - he recommended a look at the Swift, which they don't sell).

So, my question - what's the story about Dahons? I don't want to steer my partner to get a shabby bike that won't hold up. I plan to take my partner to try out a Swift, but after that I can't think of any other less expensive folders that he should consider. Perhaps some of you may have some suggestions?

I am a proud owner of both Dahons and a Brompton. My Dahons are the 2003 Boardwalk S1 and the 2006 Piccolo. My Brompton is the simple C or Companion model. All models are discontinued by their makers, but I don't think it will be an issue here. The Boardwalk was my first folder. I had it now almost 5 years. I can truly say that except for the first month I had it, I never really had any major problems with it. I keep it clean and adjusted myself with minimum work or mechanical knowledge. I am about to take it into the shop for a major overhaul tomarrow. But I don't think it is vastly different than any other bike. The critical thing about Dahons that everything can (and does) go wrong with the bike during the first month of ownership. Providing that you address it immediately by taking it back to the shop and fix it, it will serve you well for the rest of the time you have it. I had an nearly identical experience with the Piccolo a few years later. The bike shop was way better in handling the problem that bike had during the same time frame. And no more problem with that other bike either. My Brompton after it's initial tune-up never gave me any problem. If you look at lesser priced folders, consider Dahons-just make sure they are steel frame ones (Speed models are) and have most of the features you want in a bike. And don't skip tune ups!

2) HANDLEBAR HINGE/LATCH - If I couldn't stand up on my Brompton pedals and pull up or put weight on my handlebars I think I would consider that a serious limitation. Again, is the latch on the Dahon designed differently from others?I'll just mention this one - Dahon designs are fairly unique, especially the handlepost hinge. The latch mech tends to loosen as it has a lot of screw threads which are not positively retained. This leads to some play in the handlepost which can -

1)fold suddenly and unexpectedly OR
2)break off at the hinge

Neither case needs hard riding, just normal riding in the saddle. The potential for grave injury is obvious.

That said, it appears despite this design flaw there are many many owners who never experience this problem (or they never report it, just adjust often).

I am not aware of any other folder which has the same problem.

I would choose a Strida as I believe it would be fine upto the 5 miles I do by travelling on the train and when on the train I would have the minimum of fuss with it.

FWIW (sorry a bit off topic) ... I too have a doggy back and find riding in sporty positions I used to like (ie seat above bars), now aggravates it. This is where I find the upright position (as Strida, dutch bikes etc.) is brilliant ... feels like back massage instead of torture. In this position I just keep going .. 5, 10, 15, 20 miles ..... no sweat (literally). I know for faster speeds (16mph+) wind is an issue so bend back bend - but for everyday to and from work why push it ? ... you know you'll smell :roflmao: unless you've got a shower at work !

Simple Simon

Funny you should say that as I'm really looking into Dutch bikes as well! ;) In a ideal world somebody would swap their Strida (3.2 and above) for my Curve. I would use that for my commute and get a lovely Dutch bike down the line for pleasure/longer rides with my wife.

Regardless, that is I think my longer term plan :)

Thanks everyone for all your responses. It appears that there are four areas of concern

1. First, you have a new Brompton and it hasn't given you any problems. In about five years, you'll feel quite differently about the amount of repairs that await you. If you ride your folder every day, I expect you'll end up buying a new one by year 4 or 5. Happens to all of us.

The handlebar is the weak point of the Dahon folder. However, it's not really a problem because you'll notice when it's time to tighen it.

2. Proprietary parts are not really an issue. There are still first generation Dahons still on the road since the early 1990s. Should my proprietary handlebar brake, putting a new one on is quite easy. It won't be the same color or size but will work. Other than the main frame hinge, all other parts can be replaced. Not a serious flaw.

3. Seat Post slippage -- Not a problem. I have three Dahon's and fixed this problem easily. There's only one person on this forum who hasn't been able to fix this problem. There are quite a few solutions and this issue has been discussed and resolved on the Dahon forum.

4. Frame Hinge -- Other than some squeeks, it's fine. You can also cure the squeeks too.

That makes sense to me, Steve, but does that also mean that as long as one keeps the latch tightened then there is no problem pulling up on handlebars when standing on pedals?

In the end not all Dahons are the same.

You can't compare a $200 Dahon, vs. a $1000+ one.

is just like buying your MTB at your local walmart for $90 vs. buying a real MTB for $1000

If you ask people that complains about Dahons, it'll be from the group of people that bought the mid to low end variations of Dahons.

Ask any mid high, or high end Dahon owners, and you'll get positive feedback.

So, my question - what's the story about Dahons? I don't want to steer my partner to get a shabby bike that won't hold up. I plan to take my partner to try out a Swift, but after that

Don't forget that Dahon's can have a lifetime warranty on the parts for which you can't find replacements. For the other parts, even using Dahon spares, the prices are really reasonable. Any company offering a warranty like this isn't going to offer a slew of junk. Why do more people complain about Windows OS than Mac? Because there are 20 times more people using it.

in my opinion, stock dahon, especially vitesse and below in term of price, are optimum for commuting and leisure riding..if you're looking for a smooth ride..change the damn parts..the wheel set, drive train, brakes etc..

That makes sense to me, Steve, but does that also mean that as long as one keeps the latch tightened then there is no problem pulling up on handlebars when standing on pedals?

The amount of extension determines the force exerted on the hinge. . . though there's loads more flex at longer extensions so perhaps that's a counteracting factor(?).

With how long the extension of the stem on some folding bikes can be, I would personally believe it would be bad for the health of the bicycle and rider to pull on, or put large amounts of weight on the handlebars with any model - thats a pretty long pry-bar.

Personal experience, had difficulties with a Dahon Mu p8 which was purchased earlier this year. The frame's hinge was very poor right out of the store and continued to develop play in use, despite adjustment. Since then I have met two owners of the Mu (one an XL, one a P27) whom have had no problems with their bicycles in that regard, so I presume this was simply a defect issue. Aside from the frame difficulty, the Mu was a very quick little bike.

However, last month I purchased a Speed d7 and have found it to be a very stable and enjoyable bicycle. The level of componentry isn't spectacular, but it is satisfactory and the bike is a comfortable ride. I have made only two changes to the bicycle, switching tires to Schwalbe Marathon and changing grips to Ergon. The steel frame of the speed is very nice to ride on considering how small the bike is.

I had no problem with play developing in the handlepost latch for a long time. Eventually the factory threadlock went and it required re-threadlocking. Threadlock went again after about a month and I've applied a more generous amount this time; seems to be holding fine.

Hi Steve,

I was wondering if you could tell us how to cure the seatpost slippage issue ? Mine is sinking like the titanic - 5mm after 10-15 of light riding.

By the way, my wife and I tried a couple of Bromptons today, my impression ? No fun factor whatsoever, this bike is nothing but business and not in a good way, it folds fairly small but the ride quality is pretty bad, shifters and brakes are just old school, the brakes didn't work well at all and the S handle post with the flat handle bar is too low and cannot be adjusted. If I were to make a decision on a $1100 bike it would be the Mu SL no doubt.

Aha, I'd seen that and not registered the functional difference. Though surely to work it'd have to be manufactured to fit the bike with such a degree of precision. . . does anyone here have one? Ah, hang on, there's an adjustment screw of some kind to make sure it fits?

Dahons are crap, period. Flexy frame, crap dahon components. I've owned 4 Dahons and couldn't stick to one. That said, I liked the Jack.

Dahons are crap, period.That depends entirely what you are comparing them to.

A word on proprietary parts....

I wouldn't consider this a deal-breaker, but it is something to consider. Dahon changes many of those proprietary parts every 2-4 years, so it may not be possible to get replacement parts a few years down the road. Also, with some bikes (particularly the low-end ones) it can be difficult or impossible to upgrade components. E.g. it is not possible, afaik, to replace the cheapo Neos derailleur on my old Mariner.

By the way, I have not had any problems getting warranty service from Dahon.



Don't forget that Dahon's can have a lifetime warranty on the parts for which you can't find replacements....
Looks to me like they only offer a 5 year warranty. (http://www.dahon.com/support/warranty.htm) (Which is decent IMO)

if you want some true information about Dahon bikes you should read their forum
http://www.dahon.com

Otherwise you are only seeing 1 side of the coin, which is pure bashing.

which is ironic, since other folding bikes has similar if not more problems.

it is all about compromises ;)

Here's my experience. I've owned a Dahon D3 Curve since May. Since then, I've commuted every day to and from work (about 4 miles each way). One day a week, I teach Spinning and that day my total mileage is 12 miles instead of 8. In that time, I've accumulated almost 750-800 miles on the bike. Here's my experience:

1. Bike was out of service for about 3 weeks due to a striped drive-side rear axle nut. Granted I inflated the Big Apples up to 100psi trying to go faster which led to 20 flats in 4 days and lots of tube changes with a substandard wrench which probably contributed to the striping. But to be fair, that nut was made of almost-tin-like metal. I checked that's the SRAM standard axle-nut and it sucks. My boss's M-series Brompton uses the same hub but Brompton replaced that nut with some much more substantial.
2. Buy local and bring it back there for repairs. So being the home mechanic I am, I tried sourcing the axle-nut myself and fixing it (which led to the 3 week shop time waiting for parts to be shipped). I bought the bike from Brands in Wantagh, NY. As a convenience, they shipped it to me direct instead of me having to take the train to pick it up. I know my way around bikes but these things are unique (no matter which brand you buy) and getting it set up right would have helped. In any case, I took the train on weekend and they fixed it for free with a heftier axle nut in 15 minutes.
3. Overall, I like the bike for what I use it for: commuting and short trips instead of taking the subway. I have no illusions that it's very comfortable or a replacement for a proper full-sized bike. But the ability to take it up to my office and not hassle with freight elevators is worth the trade off. Let's face it, most MTBs have 3 sizes and road rigs many more. A folder has one size across most people, it's not gonna be very comfortable for long rides.
4. My routes are mostly flat. The long route has rolling hills. I find the 3-speed hub is fine for what I need. I tried the 8-speed hub as well as a derailleur-based bike. I just like to keep it simple.
5. Hinge takes a while to dial in. It took about 500 miles for my hinge to get to a point that I didn't have to adjust it. Kinda annoying but hey how many parts do you adjust 4 times a day on your "regular" bike.

Overall, I don't think Dahon's are crap. But I think depending on how much you use it, it's going to require some tweaking (better parts, more maintenance) than perhaps a Brompton. For me, it took some time to understand the nuances of maintaining it as well as understanding that I need to do more maintenance when this bike runs 2 sorties a day versus my other bikes which maybe get 1 ride a week.

As much as I hate to admit to my Brompton-riding and Brompton-loving boss, they are somewhat better thought out in some aspects. However, I don't understand the underpowered sidepull/dual pivot brakes when linears are more powerful especially given the decreased leverage of smaller wheels and why Brompton had to ship over a $450 tool from the UK to perform 3000-mile service on my boss's bike.

This is the original clamp that comes on the bike and so far I had no luck.

Aha, I'd seen that and not registered the functional difference. Though surely to work it'd have to be manufactured to fit the bike with such a degree of precision. . . does anyone here have one? Ah, hang on, there's an adjustment screw of some kind to make sure it fits?

This clamp came on my Mu P8, the screw is just to keep the clamp from moving, besides destroying the paint underneath I don't see any use for that screw, maybe my case is different because I had to remove the clamp so many times trying to resolve the seatpost slippage.

Overall I think Dahon offers great bikes, I took a Brommie for a spin and it was ridiculous compare to the Mu P8, even the Curve D3 is a much better ride by far. The Brommie felt like a bike from the mid 70's to me.

My case could be a warranty, the other Mu that I have got is fine, I need to give it a little tune up once a month but overall it's ok and pleasure to ride.
Dahon offers 5 year warranty and you can bump it up to a lifetime.
Brompton 5 year
Downtube 1 year
So it tells something about the quality.

Hi, I am curious, was it just a general feeling or could you figure out, what exactly made you feel the brommie was 70's when comparing it to the Dahons?

Dahons are crap, period...I've owned 4 Dahons...

Yet you bought 4 of them?

What are you riding now?

Hi, so basically my wife and I took 2 Brommies for a test ride, she got the M shape handlebar and I got the S post,The flat handlebar was way too low for me and I am only 5'6, there isn't a way to adjust the height ... Too bad. The brakes power was poor, it maybe enough for cruising but not for serious riding- like 15-20 KPH.
The gears are hard to operate, there are so many nice shifters nowadays I can't understand why they are still using those ones. Overall I felt like the ride quality compare to my Dahon Mu is like night and day.
I tried the bike with the M shape handlebar, it was more comfortable but there is no way I will pay $1500+tax for a Brommie. I was very disappointed.... I have to say is folds nicely, but my wife and I didn't enjoy the ride at all.

No handlebar height adjustment? Blimey. That's a no-go.

I've not ridden a Brompton but given that on my 20" folder with big apple tyres the ride is still on the harsh side, I can't see that I'd be happy with the Brompton's limitation in terms of tyre size.

With how long the extension of the stem on some folding bikes can be, I would personally believe it would be bad for the health of the bicycle and rider to pull on, or put large amounts of weight on the handlebars with any model - thats a pretty long pry-bar.

Personal experience, had difficulties with a Dahon Mu p8 which was purchased earlier this year. The frame's hinge was very poor right out of the store and continued to develop play in use, despite adjustment. Since then I have met two owners of the Mu (one an XL, one a P27) whom have had no problems with their bicycles in that regard, so I presume this was simply a defect issue. Aside from the frame difficulty, the Mu was a very quick little bike.

However, last month I purchased a Speed d7 and have found it to be a very stable and enjoyable bicycle. The level of components isn't spectacular, but it is satisfactory and the bike is a comfortable ride. I have made only two changes to the bicycle, switching tires to Schwalbe Marathon and changing grips to Ergon. The steel frame of the speed is very nice to ride on considering how small the bike is.

+ 1 for pulling on the handlebars. I never do that on any of my folders. I have noticed a huge difference between the quality of the aluminum frame and the steel frames of the Dahons. To be fair, I have only the steel frame Dahons, but I have tried the aluminum ones on occasion. While the components might be better quality than the lower priced ones I have on mine, I am not that picky about parts except for durability.
I hope that Dahon does not switch completely over to aluminum frames as that company will be just another cheap bike manufacturer-not a serious alternative to the serious steel frame preferring customer.

My Boardwalk already passed the 5th year of it's existence. I am planning to keep it until the major parts (the folding latches and levers) fail. Then I will discard it. I feel that I already got my money's worth out of the bike at this point. So I did not lose anything in the process.

You might be only seeing one viewpoint at that site-whatever the people over there wants. I find it more accurate there. Folding bikes are compromises in of themselves.

To each his or hers own. Owning and using both bike brands gave me a unique view on what works and what does not. Dahons are great “starter” bikes-an introduction to the world of folding bikes. They are very affordable and nice-except for all those fussy little adjustment screws and levers and latches the bikes were made of. I learned to live with them but I am not a great fan of them. The Brompton is more simple and direct in their approach to their bike design. This simplicity has made their bikes more easier to maintain. And a more compact fold. Being handbuilt makes them a solid individualistic feel for me which a mass produced product like Dahon lacks even in it's higher priced line.

I fixed that problem on my Brompton's brakes-and it is the single pivots ones-by simply rotating the brake levers up a small amount toward the top of the handlebars so my smaller hands and fingers can reach them and give me more leverage. I even take the bike on hilly terrain with no problems in the braking area now. I changed the shifters to a simple Sturmey-Archer metal one which matches my rear hub. I chose the bike for the ride quality as you found out for yourself. And the M handlebars are the best as far as luggage carrying and comfort is concerned. For most, the price of the Brompton is the major put off of the bike.

Sorry if it wasn't clear but I meant that the ride on my Mu is much better than the Brompton, on top of that I paid $550 after tax for the Mu while the Brompton is $1500 before tax, if wanted to upgrade gears, shifters and other stuff it will be so pricey. For my needs Mu SL would probably work better.
The Mu P8 is pleasant to ride and it is 1/3 of the Brompton's price tag, so yes... it doesn't fold small like the Brompton but it is a much better ride.

Mu folds way faster than anything available out there.

Just to be clear, since I am the originator of this thread, while I love my Brompton, I have never been under any illusion that it is the *best riding* folder out there, nor do I think that most people purchasing one believe that either. I am very aware that there are lots of folders that excel in quality of ride, but for me fold size was a top priority and I find the Brompton's ride perfectly fine for my needs and in fact very enjoyable (I will add in response to the one post criticizing its brakes that I find the dual-pivot brakes that came standard on mine to be as good as I could ever want.) Anyway, the purpose of my post was not to compare Bromptons to Dahons in terms of ride. I fully expect my partner's less expensive folder to ride better than mine, since as stated in my original post, folding size is a secondary consideration for his bike. As many have stated, it's all about compromising to fit personal needs.

Once again, I thank everyone for contributing to this thread. My purpose was not to disparage Dahon bikes, but rather to seek an explanation for negative comments made by others about a bike I found very attractive and enjoyable to ride. Comments made here have lessened my apprehensive about their mid to high range models, although I'm reserving final judgment for when we can check them out again in person.

Fair enough.... Just wanted to add that I honestly believed that Brompton, by its price tag will be a much better ride than Dahon and this is why I went downtown to test a Brommie.
In the way I see it, folding bike is a good folder if it fits your needs....

The cure for the Dahon slipping seatpost is to remove the turtleneck clamp, pry out the shim that sits inside the seat tube and grease the outside of the shim, then re-install.

My 2007 Mu P8 suffered from the problem from the time it was new until I followed this advice. Before trying it myself, I could hardly believe it would have that much of an effect, but it really works. Apparently this helps even out the force of the clamp around the seatpost instead of concentrating in only a small part of the surface.

It is indeed hard to see how that would work but somehow it works at least for some people. :thumb:
