Anyone have any experience with folding bikes?
I'm thinking of getting one for commuting, but the 20' tires (with a 52x14 lowest chain combo) worry me a bit in terms of speed.
Calculations say I'm gonna be needing 90rpm+ to maintain any sort of decent speed (in the range of 30km/h).
So, how hard is it to gotta go fast with a 20'' bike?
And just in general, anyone who uses or used a folding bike, what are some pros/cons that you've noticed?
