Engineers ...

[Not] coming soon to a bike shop near you: An upright handcycle?

But, hang on ... the rider's legs were also spinning!

I'm sorry I didn't stop to chat with the fellow who rolled up on this curious machine, but it's a safe bet it was none other than Stanford's Richard Reis. (The “Full Body Bicycle” placard mounted on the front was my clue.)

A good 20 miles from the university, Dr. Reis clearly gets around. If our paths cross again, I'll ask why he didn't opt for belt-drive instead of chains. (Belts weigh less and need essentially no maintenance.)

In any case, I wouldn't want to cruise downhill on that thing ...
