Hey guy,
So I was thinking about making a motorized bicycle but my idea is a little different basically I want a pit bike but I dont have the money so cause there like 900 for a decent one. Anyways i was thinking get like a little but strong engine like a 4-5hp and put a speed transmission on it. I was planing on not having pedals and cutting and reshaping the frame to get the engine in or on.

Bike is going to be used for tricks in parking lots
have anyone done this before?

does anyone have any suggestions of engines like a little atv or mini bike engine or something.

thank you
