hello, im a long time builder of motorcycles and cars but new to motor bicycles, i tend to go a bit overkill when i build anything, and i hate using off the shelf kits. my bike started as a brand new mongoose 29er with disc brakes and i shoehorned a 1971 sachs saxonette 2 speed auto 47cc engine into it. had to post here first but ill post my project in the frame mounted section shortly
