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?

What you are looking for was marketed and known as a "Whizzer" bike back
in the 40's and early 50's. The motor mounted in the frame just above
and slightly ahead of the pedal crank. Do a google and see what you can
find. By the way, I had two and they used a simple centrifugal clutch
with v-belt drive to the rear wheel. Should be easy to clone one.
