Ted Wojcik of Ted Wojcik Custom Bicyclesdesigned and built this pedal-powered lawn mower with a fixed gear in it so it can go forward and backward — which is essential when using a push-mower. When you stop pedaling, it stops moving so it doesn’t require brakes. I doubt if it would be a good gadget here in West Virginia, where we use a regular old push mower, but it might be useful for someone with a really large, flat-ish yard!
