Additional FeaturesI modified the rear section to take an Avid mountain bike disc brake set up. The adapter was from EV Deals, the brake is stock bike shop Avid BB7.

I had to remove the original battery box and fabricate a new one to fit the 4.5" X 6" X 11" LIFEPO4 battery.
This scooter is a smooth ride at fairly high speeds. It has twin rear shocks, and a suspension fork. It is made in Taiwan with higher level of components than most of the small power board type of scooters, including very heavy duty smooth rolling alloy wheels. I have even ridden on some dirt fire roads. It climbs hill well with my 170 pounds on it. I can go up 10% grades at over 20 MPH. Could use a few more amps for the longer, steeper hills. Taking off from the line it gets to 20MPH pretty quickly.

Motor and controller run fairly cool even after an extended run.
