because of the high proce of gas, would putting a motor on a bicycle be practicle to get to work a few days a week? I live about 18 miles away it is all highway with a wide berm for bicycles. I have a spare 5 horse motor from an old tiller. Could I mount a bracket and put it above my back wheel to drive the back wheel on my 10 speed mountain bike? Would I be able to pedal it home if the engine failed? How would I rig a clutch of some sort or would I even need it? Seems like an interesting project.
How fast could you go with a 5 horse motor?
