I want one.
How come the guy starting it isn't the guy riding it?

We used to make motor bikes. Find a bicycle someone was throwing away and get rid of the pedals and sprocket. Bolt an angle iron to the frame. Mount the engine to the angle iron. Get an old washing machine pulley and bolt it to the rear tire spokes. Run a belt from the rear wheel pulley up to the motor pulley with a tensioning pulley along the way to pull up (sorta like a clutch).
Optional was a handle bar grip twist throttle .
Even less optional were brakes. You had to use the caliper brakes, not the pedal skid brakes that were common on one speed bikes.

Filed under: Just because you can, doesn't mean you should.

It was fun, and we made some money from them.
Engines we scrounged from the trash, old lawnmowers, etc.
Learned how an engine worked. Learned how to rebuild one.
Learned newtons laws of motion outside of a classroom.
