8-speed gear ratio drive chain assembly driven by motor(no pedals installed). In small neighborhood can get 30mph in first gear, 34 mph in second, had to slow down after that, not enough road. After I have it street legal I will leave the neighborhood and test top end out. I'm anticipating around 60 mph. If that is not achievable with this bike I will at least boost the gas mileage at an enormous rate. There is a dynamo installed on the wheel that keeps ten AA batteries charged in case I need to change the batteries on the lights. No need to plug into the wall.

This happened on the first test run, brakes failed on me. If you custom build a bracket for disc brakes for a frame that's not built for it, make sure it is tough.
