If a Dahon Speed 7 fit me, will a Curve D3?

Love the look of the smaller wheeled bike. I was able to find and try a Speed Seven (which fit me fine) but not a D3. Any one 6 feet tall tried them both? The seat post on the Speed 7 still had about half an inch left to raise when it felt comfy for me. Any feedback appreciated.

I'm 6 feet tall and ride a Presto, the precursor to the curve. With the seat post at full extension it is just large enough for me. I keep the handle bars slightly below seat level for easy folding. I use it for shorter rides and find it comfortable.

Not necessarily. I'm 6' tall and I can fit onto a D7 comfortably, but I wouldn't complain if I got a couple inches of extra effective TT. I tried the D3 the same day and found it was a bit smaller than the D7 which was a deal breaker. Too bad as the 16" wheels with big apples + internal gear hub were nice.

When I got my Tikit I got the large frame and it was so nice to have that long TT on a folding bike.

Now having said all that I did ride the D3 and it wasn't impossible so if your rides are short and you REALLY want a D3 figure out a way to get a test ride in. But, just be honest about how long you'll be on the bike at a stretch and how comfortable the riding position will be for you.

Thanks for the additional information and the pics! I had to travel 70 miles one way to see the only folding bike around (a Speed 7). That dealer will be getting in some other models as soon as they ship. Perhaps I'll wait and see what fits better (which would be nice even for shorter trips around town).

I'm 5'11'' ,but have fairly short legs. After adding a stem, my Curve SL fits me very well. I use it to commute 12 miles/day and it works great and folds faster than I can lock a bike.

I have almost 1500 trouble free miles on this bike.

Edit to add: My wifes Mu p8 fit's me pretty well with no modifications, but is still a little short for me from seat to handlbar. Someone who prefers a more upright postion probably wouldn't complain.

When it comes to fit, it is more of a matter of how your own torso/arms/legs proportions match the bike's own. While I am well under 6 foot, I have rather long legs for my size (30" inseam), shorter arms, and shorter reach than a typical man (I am female). I have both a 20" and a 16" Dahons. I have to raise the seatpost pretty much it's maximun height as I do my other folder, a Brompton. The reach on my 16" Piccolo is fine for me as the Brompton is. The 20" Boardwalk is a bit farther, but not bad as I like to ride in an upright postion now. It would be rather stretched out if I rode tucked in or bent over. Either way, I recommend that you try all the interested models out before you choose and buy. That will make or break your enjoyment of these bikes.

How does it fold with the extra stem and grips? Or do you leave the handlebars up? I do feel like the cockpit is a tad small for me on the Curve and that looks like a good mod. Thanks!

Hey

I am a 6 footer looking to buy a 16 in bike also and I had the same questions as you. I tried out the D7 and it fit really nicely..........I got the chance to try out the D3 Curve and it also fit nicely............I don't know too much about bikes but it confuses me that some people who are my height and weight at 160 pounds, think the bike is too small for them. I only rode the bike for 10 minutes but it was a lot of fun.

And can't you just adjust the stem or seatpost up or down to get extension for taller riders, solving the height problem?

Well keep up the posts here or read my older ones please....I'm gonna get a bike soon, and now really leaning towards the Curve.

It's so nice to be able to try one before you buy. Many people have different ideas of comfort depending on riding style.

Regarding the fold of my Curve. The fold is the same and I think it is faster, because I don't have to worry about moving the post up and down and rotating the handlebars. I did have to modify the stem a little to get it to go more vertical and added a quick release instead of the allen bolt so I don't need tools.

Folded Curve SL


modification to stem and added a seat bolt style quick release.

I'm a bit confused by the perceived differences in fit for taller guys between the Curve D3 and the Speed D7

According to the Dahon website (in inches):

Curve max reach = 25.4
Speed max reach = 25.4

Curve max seat height = 37.4
Speed max seat height = 37.8

Seems very similar to me.

What am I missing?

I'm not sure where they get that. I think the Curve is about an inch shorter from seatpost to handlepost. If you would like some specific measurements, just let me know what you would like.

This thread has some Curve d3 measurements that could be helpful.

Ok, cool. That looks do-able. May I ask what were the exact parts you used? I haven't done a modification yet, so I don't know what brands make good parts. Also, I've seen a couple using those grips--what brand are they?
