Big Block mid drive with one stage reduction. This high torque motor has up to 6000 watts of power to climb steep hills without extremely low gearing. It can be run with a single rear wheel sprocket or with a derailleur. Because of the fast chainwheel speed this drive runs on the larger rear sprockets and is not meant for pedaling along with the motor. For a pedaling mid drive please see our multiple stage reduction drives. FOR OFF ROAD USE ONLY. NOT LEGAL ON PUBLIC STREETS OR BIKE PATHS.
