The Innovate or Die Pedal-Powered Machine Contest sponsored by Specialized and Google challenged participants to create a pedal-powered solution for offsetting climate change. When it comes to efficient energy use, the bicycle leaves all other modes of transport in the dust; for the same effort required to walk three miles, a person can easily travel 15 miles by bike.... although have you ever tried pedaling 15 miles on your big fat downhill beast? Actually, I do know someone who pedalled from Lands End to John O Groats on an Orange 222.

This racy looking trike below was the winner.

Some of the other entries are pretty bonkers.
