Alta’s proprietary, water-cooled motor controller is a clean sheet design. Both the hardware and the software were developed in-house to integrate seamlessly with our high-speed, permanent-magnet, brushless motor. The controller transfers a direct, instant connection between the rider’s throttle hand and the rear tire. The relationship between the controller and the electric motor allows riders to tune their bikes' power to their riding conditions and riding style. Through pre-programmed throttle maps, riders can adjust the rate of acceleration and amount of engine braking to respond to changing conditions like hard-pack, turning to mud.
