Guan Baihua on his multi-angle-wheel bicycle.
Check out this bicycle with a pentagonal wheel up front and a triangular wheel in the back. Both are known as Reuleaux polygons. Unlike a bike with circular wheels, this one requires more work to pedal. Which is fine with inventor Guan Baihua who reportedly says he made this bike so that cyclists could get more exercise on their daily commute.
According to Marcus du Sautoy of TimesOnline, the ride of such a bike looks like it would be rough but it's actually supposed to be quite smooth. That's because the height of the bike seat in relation to the ground is constant.
If you have any information about this bike, please let me know. I'm in the market.....
