Additionally, the Crane 8 has a 306% gear range with 8 speeds, so you can tackle any terrain.


Thanks Paul - this did it for me -- I just bought 2 today through Jet to save a few bucks -- look forward to getting them in Downtown Jersey City - we ride a 15 mile long loop on the waterfront everyday - both here or sometimes across the Hudson in Manhattan. Thanks - can't wait! We got the grey/black - but do kinda wish you still had the orange - Princeton's colors. Cheers!

I am not intimately familiar with all the bikes you listed.

However my two cents would be I would only buy a folding bike with a cassette rear hub. I would not buy a 7 speed---normally has a freewheel. Virtually all the 8,9,10 speed rear hubs will be cassettes.

The big advantage of the cassette hub is they normally have an 11-32 rear cog. The 7 speeds with freewheels normally will have a 13-32. The 15% higher gear is critical for how I ride my bikes. When going slow I don't pedal very fast, when going fast I want a high gear ---88 is high enough that I would not "spin out" on flat pavement without a tail wind. A 75 high gear (normally the high gear on a 7 speed) is too low and I would be spun out a significant portion of the time I ride.

I have in the last couple of years become a folding bike nut.

All good advice. The Crane 8 models that he purchased do have a cassette with an 11 to 34T range.

We may do orange again in the future, but lately we have received more requests for blues. I am curious to know what colors people prefer.

power of marketing I guess
Calculating gear inches is pretty simple actually.
(number of teeth on front chainring divided by number of teeth on rear cassette) times tire size
No marketing ploys at all.

There will be tradeoffs whenever you're buying a bike. I think that is even more the case when buying a folder. Consider where and how you'll be riding first. Then look at the bike quality, components, gear range, weight, folding size, tire size, etc. There will be compromises. Prioritize what's important to you and you should be a happy customer.

Hi, first post, joined this excellent fourm because am in the market for folder to carry in car.

It is daunting for a newby to understand gear inches, gear ratios, IGH, freehubs, freewheels; not to mention 16" vs 20" vs 24" size wheels, 406 vs 451, frame geometry, suspension vs non-suspension vs seatpost/tire inflation, online vs LBS, and the plethera of folding bike options available.

When I was a kid you just went to the Western Auto store and picked the red or the blue one ��. One speed fits all.

I hope HarveyCat posts his experience of the bikes after some use. The 52 chainring matched with a 11-34 8 speed cassette on a 20" wheel sounds like an attractive option for a drivetrain. (Did I state that correctly, lol?)

I'm not a newbie and most of the technical discussions go over my head. I read them anyway just so I'm kinda cognizant of what's going on. If I really need to understand something, I kindly ask the informed to explain it in dumb bike people language to me.

I have no bias as sadly don't own a folding bike company or retail folding bikes but of those listed I would go with the Origami Crane as a preference. However another option would be the euromini urbano.

https://www.euromini.bike/urbano-red

Like the Crane it has a cassette based drivetrain and double wall rim wheels for strength but offers a longer lifetime warranty on the frame plus a slightly higher rider weight capacity (10lbs). However it doesn't include the rack or mudguards of the Crane.

You are paying reasonable money for a folding bike you really shouldn't buy anything with a freewheel or tourney gears for that sort of money which would be any 6 or 7 derailleur geared bikes. It's fit for purpose at entry level I guess but for long term reliability and strength you should make sure its a cassette based drivetrain and many such bikes are within your price range.

The entry level models from higher priced brands like Tern and Dahon are often rubbish with low end drivetrains and best avoided in my experience but their step up models in the range are often good machines if not particularly good value compared to other bikes.

I bought a Crane recently. The 52-11 combo gives it a 92 inch top gear, meaning that when pedaling at 80rpm you would be going around 22 mph. I have an older Schwinn touring bike with 27" wheels and its top gear is similar.

I want to learn how to calculate gear inches...so taking advice from this thread, I calculated the following:

52/11 X 20

And I got 94.5 instead of 92. Did I use the wrong numbers? I'm pretty sure I'm using right formula.

I calculated my Dahon D7:

52/12 X 20 = 86
52/28 X 20 = 37

Hmm...my biggest gripe with the bike is the limited gear range. I could use a little more help going up some inclines.

Your best bet is to use a gear-inch calculator such as that on Sheldon Brown's page since the 20" is a nominal size, so a 20x1.75 will give you a different result compared to a 20x1.5

Crank length and tire size are part of the equation.

Factor in tire size, and crank length, and you'll have the answers you need. It works for me every time.

Wow, awesome. Why have guys kept this a secret?

My Dahon D7's gear inch range is still pretty limited, but it's nice to know so I now know what to look for if...when I buy the next folder.

As a fairly new folder owner I too overlooked the gear ratios. Like others mentioned, just figured gears would be more like a normal bike. It worked out for me because it was an easy fix but I do think that this is a critical area to get educated on when purchasing. On the flip side it probably got me more into the bike because I had to learn (kudos to this forum) and gain confidence in making modifications, so now this is more than just another bike to me.

Best of luck!

I want a folder for the additional riding oppurtunities it will provide me. So far the only wheels I am spinning are in my head.

Like tdonline, I too am more concerned with the low end of the gear range. My knees prefer spinning to grinding.

Is 30 gear inches a good number to shoot for to pedal into a strong wind or to spin up a hill?

30 gear inches should allow you to pull a trailer, uphill, in a head wind.

That is really good I created a small spreadsheet while I was training to use excel concerning bike specs and ratings and I've put about 20 folding bikes into the spreadsheet but none are as fast as that as standard bikes. As you say its more typical of a good quality full size bike. I might just add the Crane in there to see how it stacks up overall.

Part of the excel sheet but you can see none of the bikes shown in that segment match that speed.

If you need any additional information on the Crane 8, just ask.

Cheers but your site is actually one of the better ones for providing a full spec. I had to resort to searching forums for the right information on a few brands that keep their spec vague but no problem with yours. Saying that I haven't actually put the Crane bike in the excel sheet yet but when I looked previously the information looked better than average. Best one was the euromini site though which has a very comprehensive spec including a large number of measurements.

I'm on the wrong side of the pond. Not only do I already have a bike of similar spec but getting one of these would incur extra duty and shipping costs. Not even sure if I can get one sent to the UK from the US.

Reviews here, mostly positive except one which is more about after sales than the product itself.

https://www.amazon.com/EuroMini-Ligh...%2Burbano&th=1

Plus a review video of sorts here;

The Urbano seems like a solid, low priced ride IMO.

I added the Crane and it turned out alright according to my criteria for what is a good bike. Came 7th out of 50 bikes I have in the spreadsheet. It's low weight and fast gearing gave it a small advantage over many similar bikes. Scored 150 out of a maximum 230 points. It's bike no.8 and actually pushed my folding bike at no.4 from 7th place to 8th place. Fastest folding bike I've put in the spreadsheet but I don't have higher up Tern or Dahon models in the list only their entry level models plus a classic Dahon model. I think the only folding bike that scored higher was a Nexus equipped model. I will probably add the euromini bike at some point but it may not score as high as it has slower gearing.

https://drive.google.com/file/d/0B8N...ew?usp=sharing

Later I stuck the Euromini Urbano in there and it ended up with a 1 point advantage scoring 151 and taking 7th position, moving the Crane down to 8th and my bike down to 9th. I basically gave it an equal points rating for speed despite the gearing because it was lighter and it got an extra point for hill climbing again due to weight and slightly easier gear ratio. Pretty much everything else was rated the same I think. At some point I will put a few extra Dahon and Tern bikes to see how they fare. At some point I will do tailored ratings for each use, off-road, all weather, speed, urban commuting which only includes points relevant for each use. At the moment its an overall rating for everything.
