Now that the Curve has a derailluer, I have no desire in getting an SL. I suspect Dahon dropped the Nexus Red Band 8 speed to keep the price below $1,200.00 US dollars.
Speaking of underrated! - for some reason the Capreo system seems to get no respect in comparison to just about any IGH, while it is the biggest reason I like my 2009 Curve SL more than my old '07 SL! It's fantastic! Initially, I was perhaps influenced by these boards, half expecting a maintenance nightmare, but after 7 months of almost everyday riding it has needed only one, very easy to do, adjustment. The gear range is perfect, shifting is extremely smooth and very quiet, no skipping, no chain jump ever.

The SA 5 speed internal hub on the '07 was OK but extremely finicky, requiring a very precise adjustment way too often. It also was noisier and would skip gears from time to time. I couldn't stand on the 2007 with confidence. No problem on the 2009 SL.

I realize the 8 speed Nexus Red band and Alfine hubs are supposed to be great, but I really don't see any big enough reason to choose them over the 9 speed Capreo derailleur which has worked so flawlessly.

Indeed. When I get back to the states, I will probably be upgrading to a Capreo on the Tikit. Not an IGH.

Having said that, I am becoming more and more intrigued by beltdrive systems. If I could fit an Alfine IGH with a Gates Carbon beltdrive to the Curve, I would definitely be tempted to ditch the Capreo - but only that.

Just had a look at my Downtube Mini; it is 400mm axle-to-BB and has a 965mm wheelbase. The Mini handles very well, and I can only think that the improved Curve will likewise handle very well or better.

Short wheelbase making the center of gravity to be ahead of the front wheel while going down stairs or doing any other urban aggressive maneuver.

I've been riding an Abio bike with belt drive. I'm really liking it too. It's quite and clean and remarkably reliable.

Made some fun modifications recently that I'll be posting up too.

Trust me, I am not making this up. I obviously posted this and the other photos long before "Find-A Grave" used that same photo (without my permission-Pickles might be a college student, but he does practice Internet plagiarism). So in a way, thank you East Biker, I would not have Googled Cindy's name (it still upsets me even after over 30 years) & found that illegal usage or "borrowing" of my photo of her. And I will always be proud to have been her friend, no matter the price like dodging the newshounds (now called the "Paparazzi"), living in fear of strangers for almost a year and other horrible things I tried to forget until this brought it back. And this extends to the rest of my both living (you have met them already) and my lost loved ones (Cindy September, 1957- February, 1978) (My Father, August, 2005).

I will "see" all of you I hope soon perhaps here or on Foo. My Brompton has now joined the Dahons and even the sewing machines in storage. This computer might go with them too for a little rest (We'll see).
This really proves nothing. Anyway, if your absence means that you will be no longer around to bash Dahons and cost Thor part of his livelihood, then it would be for the better.

To OP, I think you won't go wrong with either. The Dahon might be better handling though because of the longer wheelbase. I think the L5 has a shorter one and that the current Bromptons have a longer wheelbase, but I am not sure.

I created this post in order to provide people a comparison of the folded/unfolded size of both bikes since this topic has been asked before, but I haven't seen a side by side picture. Not sure what all the fuzz that happened on the previous post was about.

1. The OP already owns both and was providing us with a comparison, not asking a question.
2. The Brompton still has a longer wheelbase, not the Curve.
3. IIRC the Brompton had it's wheelbase extended at some point. So I agree on that.

However, I don't think <100mm difference in wheelbase can possibly be enough to make any significant difference in endoing. Sure, it might change the handling of the bike and you might be able to feel it, but realistically we're talk about such a small percentage change in dimensions that I find it unlikely that the rider shouldn't be able to adjust.

agree... a couple mm here and there usually make a very small difference, more important are the fork runout, angles of the seatpost, handlebar, and and and... combine that with a different statue of almost every different rider ( even when the same height, there might be a huge difference in leg length, arm length , where your center of gravity is located ....)

see ..I have a big head ..therefore I use my beer gut to balance the center of gravity somehow...lol ..

there are hundreds of differences between each bike and each rider, therefore there is never gonna be one best ...

Thor
best bike ever ?
the one which is used and gives the owner pleasure in doing so

Personally, I have not experimented enough with wheelbase to make strong conclusions. But people seem to make a big deal over 2 inches. So it might make a difference in the satisfaction with a bike.

More generally, handling, comfort, and such is due to a combination of a lot of things. But in all likelihood -- speculating here -- having an extreme value in one aspect of geometry can only be partially accomodated by other factors.

Since wheel base is roughly the same as a road bike and your the tires are smaller you have lower center of gravity on a folder. So your less likely to rotate over the top of the bars when you stop then if you riding a road bike. And you will have less height to fall from. Always a consideration when purchasing a bike to ride down stairs with.

But wouldn't the location of the person relative to that front axis be the most important factor?

That's because 99% of all bikes are almost exactly the same. IMHO most cyclists make a big deal about things that don't matter and there are many variations in bicycle design which would work just fine if people were willing to get used to it.

Satisfaction is another question entirely because some people (perhaps most) won't be satisfied no matter how good the product is if it doesn't fit into their narrow view of how a good product should function.

Or maybe the front axis relative to the fixed point of rotation (ie the step that snags your wheel).

Is it just my imagination, or are you guys debating the relative merits of different wheelbase-dimensions as it relates to riding down stairs on small-wheel bicycles?

Gee, my eyes are sore after reading the whole thread. I have a Brompton M5R & M3L and 5 other Dahons (Roo El, Helios SL, Speed Pro, Cadenza). All I can say is every single bike was created possibly by different designers & engineers in difference time frame. Therefore, the characteristic & their business models change accordingly. The only thing we as the customer can do after you bought their products is to try to find ways to utilize them as much as possible. I would also be nice if we can share information here to other owners on making their bikes better. This is what human race is all about at least in the folding bikes world.

lol its reallt easy ... Joako started out with a very nice biased free comparison about the Brompton and Curve folded size.
Than all kinds of " VS " started ..... with tidbits of actual information thrown in for good measure ....
Than we had a meltdown , which resulted in a "challenge to get spare parts" another even greater meltdown, the challenge resolved, more good tidbits to the original thread, a new thread about sizes and so on ... more or less three threads wraped into one ...

its complicated ....lol

They have longer levers ('4 fingers') compared to the stock ones I have and the bell is easy to reach and sounds well (at least in our living room). They are slightly heavier (about 100g extra per pair) but the longer levers and the integrated bell justify it for me.

Thanks again Thor.
