Additional FeaturesEvrything is bolted on and can be removed and put back to stock. I designed everything so that I can put a gas motor back on or change it later if needed. Motor runs in the right direction through a gear drive primary.
Planned changes : street tires and maybe lights.

Rebuilt everything on the chassis including new swingarm, bearing , seals , brakes but still needs a lower friction chain without O rings.

Eteks self destruct if you run them backwards (ccw), theres no easy way to fix it or prevent that. Potting the armatuer helped with the extra power I am running through the motor and reinforcing the output shaft prevented another failure point visible after disassembly.
