my Bike Friday Crusoe
My BF Crusoe is built up with contact points identical to my normal road bike. This includes drop bars, Brooks saddle, and clip in pedals. I think I notice the inertia quotient of smaller wheels, but other than that I can stand up on the pedals and climb just as if I was on a fast upright normal bike. I know my Crusoe is not the typical folder in some ways, but that is why I like it a lot.
