Designed and built by the same team that brought us the original E-tek motor the ET-RT is a stout 38 lbs and produces some 18hp peak, this radial motor can do 125 amps at 72 volts continuously (300 amps peak) and runs in either direction. Higher torque and slower speed, this is ideally suited for 72 Volts. Works with Alltrax and other PM controllers. Good for heavier motorcycles and go-carts. Similar in performance to the PMG-132.
