GMAC High Voltage Kit

Rear GMAC conversion kit with 72V battery pack for high speed applications. Includes high torque geared motor with locked clutch for regen, optional 72V downtube battery pack and charger, Phaserunner_L10 motor controller, wheelbuild options, a V3 Cycle Analyst, and your choice of PAS sensor. This is a kit that is optimized for unforgiving high speed travel, and the motor temperature sensor with the CA3's thermal rollback and the Phaserunner's phase current limits keep the performance in check.
