Motorcycle Repair: Home made motor cycle, motorised bicycles, google search


Question
Hello, i was wondering as to the feasability and cost-effeciency of somehow replacing the pedals on a bicyle with a small two-stroke engine and rigging the shaft to the gear chain. Doing so would presumably result in a motorized bicycle.

I have access to a work place wherein i could easily aquire the tools necessary for such an operation, so the only expenses would be the cost of the engine, and my time [of which i have an abundance at the moment].

please provide information helpful to me in deciding whether to do this^ or to purchase some sort of motorbike

Answer
Hi Will.

Been done.  It's called a moped.  The original production motorcycles, in the late 1800's and early 1900's were just that.  A small motor attached to a bicycle.  However, the simpler solution would be what many have already done.  Simply attatch a small motor to the bike behind the seat and have it turn a wheel that pushes against the rear wheel.

Look up motorised bicycles in a google search and you will probably find tons of info for your idea.  You can also check for a photo history of motorcycles. There must be one out there.

Good luck on your project.
Let me know how it comes out.
Ride safe.
