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?


Use an electric motor, you won't have the fumes and won't have to stop
for fuel. Just unroll the extension cord as you go to work and roll it
back up again as you come home.

A variable frequency drive would allow you to use a 3phase motor and have
speed selection, this would be an asset in traffic.

John,
Hate to bring up the normal response, but...

What gauge wire would that need to be for the extension?

VFD would be nice, but lose about 1/3 of the HP on the motor. RPC might
be a better choice.


Of course, if he lives in a city with electric trolley buses then all of
his problems disapear. More people could make use of this free and
convenient overhead power source. 400 volts DC and enough current
available for even the most outrageously overpowered electric bicycle.

LMAO.

Although very feasible. Could you imagine some nut driving around with a
pole on his bicycle to catch the power from the trolley lines? Better yet,
no tires to wear as he would have to ride on the track as well.

Than again San Fran is full of nuts and trolleys. Wonder why we have not
seen it.
