Answer 1

That kit is as cheap as I have seen, but the cheap kits are notorious for the amount of tinkering you need to do to make them work for you. With a bit more tinkering the cheapest approach is to fabricate your own out of an old weed whacker. The simplest drive would be a friction/spindle drive. Search google, youtube and instructables.com for "motorized bicycle" for lots of good ideas.

Answer 2

I know of one that is REALLY cheap!

If YOU act as the motor, sit on the bike and pedal you will get forward motion without ever having to fill with gasoline or plug in!
