Yep It's way cool but for that kind of money, I just don't know, If I wanted that level of performance and was going to spend that much I'd want 700c wheels and a full size folder under me. I just don't see it with 20" wheels and a compact bike..

It Is beautiful but it would be like buying one of those Hot Rode three wheel Slingshots while knowing how much 4 wheeled car I could get for the same money...

I just couldn't do it...

Full sized folder?? An IF Move *is* full sized. It's designed for adults. And on smooth road, there is negligible difference in wheel performance between 700c and 20". Look up speed records on upright bike, then check wheel size. Or look up land speed records on recumbents, and check wheel size.

In the USA, in quite a few areas/city's, there are almost no smooth roads to ride. Manhattan is a bit of an exception, but in Queens & Brooklyn, where I ride, a large wheeled folder is the preferred choice for most (that I've seen). There's the occasional Dahon or Brommie, but I actually see more Montague folders than anything.

That would be ignorence, largely. See this thread Why small wheels are not harsher than large ones
for the reason.

No, it's ignorance on your part. Even with your detailed analysis I find my Gravity SS 29'er w/Schwalbe Big Ben's make my backside less sore than riding my Minivelo w/Maxxis 20x2.35" tires. And I didn't need to modify my riding style to achieve this.

Also, did this include big, gaping potholes? And being required to ride through areas where the road is completely removed and industrial repair work is being performed?

Your environmental experiments are wonderful, but cover the conditions YOU are subjected to. I speak from MY experiences. And when both bikes have fat tires, and both have nice strong rims, I get the better & less painful ride via a larger wheeled bike.

I think you're over-stating it. Comparing a 1.5" 16" tire to a 23mm roadbike is somewhat questionable. And it is true that when talking about large bumps/steps wheel size is going to make a difference (if you don't believe me, take your folding bike off-road and you'll see what I mean).

For most reasonable roads, small wheels work fine (my standard ride has 20" wheels; my small folder has 16" wheels). But I can see for some really crappy roads, bigger might just be better.

No, I wasn't overstating anything at all, the 2nd post which I was responding to, clearly mentioned 700c wheels in response to the road-style 20" wheels in the OP. I never brought crappy roads into the equation. If you read my FAQ I clearly say that for wheel-sized road obstacles, a 20" wheel isn't your best performer.

I have ridden a 16" folder on a mountain pass, the infamous Breedsnek Pass when it was heavily damaged by rain, and although I readily admit a 29er would do a lot better, I dismiss out of hand the thought that a 16"er is completely unsuitable for your examples. It is less forgiving about tyre pressure so that would need to be addressed to be optimal. Plus the longer stalks actually contributes more than you think, on top of the fat tyre effect. Of course I would expect front suspension to be a winning factor here, something not many folders have, but Montague mtbs do. So comparing mtbs with front suspension to folders with generally no fs is not realistic. If these Montagues are of the 700c variety, well then we are back to my math analysis. I see bucket loads of ignorance.

The whole *#& point of this conversation (not whatever thread you decided to link to) was talking about wheel size for crappy roads. If you're ignoring crappy roads, you're ignoring the whole point.

O.k. This is getting silly and off-topic. The bike posted is way cool. Let's talk about that.

It seems only his link and equations are important.

Now, the bike is sweet, but I'm more a fan of the custom modded Tern that's been posted. More my style,...
