I'v just started building a motorirzed west coast chopper bicycle. I have very few tools and mechanical knowledge. however so far i have constructed a new mount for the rear hub simply by using longer bolts and a piece of sheet metal and a few nuts. very cost effective and easy.. if i can do it anyone can. believe me. My intention is to keep the ability to use the front crank as this makes the australian laws "foggy" in the legality of riding it. tomorrow i will be mounting the engine. hopefully all goes to plan. it has taken me one day so far so someone with the correct tools should be able to complete this task alot easier than myself in alot less time. i would appreciate any helpful hits or tricks throughout this project. ill post pics as i go along. happy days
