This is my first Motor Bike build. I bought a Schwinn Legacy from Target on sale. The engine is a Grubee Gen II 50cc angle plug ordered from USA Bike Motors. The motor mount is a proto designed and built from Jim at Creative Engineering. The sproket adaptor and sproket was also from Jim. I found Jim to be very talented machinist with alot of good ideas. It was a real pleasure doing business with him and talking about my build and motor bikes. i highly recommend his services.
