I think this selection shows that it is very difficult to improve on the standard bicycle through design.
I like the Alta One, and the joyride, and the black German bike at No2. The only really innovative bike is the monowheel! Don’t fancy giving it a spin myself tho’, think I’d end up in the canal!!
