This is a front-wheel electric conversion system made for the EZ-3 USX HD trike. It uses the SINET platform with a 500W nominal front hub motor and an integrated sine-wave controller. The existing rear axle and drivetrain stay unchanged.
The 48V 15Ah lithium-ion battery slides into the SINET battery/controller cradle, which houses the controller. EZ-3 USX HD-specific mounting hardware holds the battery on the trike. A Topeak handlebar extender provides a mounting spot for the LCD.
The system is configured for higher-load use such as cargo hauling, daily transportation and extended riding. Pedal assist comes with either a cadence sensor or a bottom bracket torque sensor. The cadence sensor detects crank rotation and does not measure rider force. The torque sensor measures how hard the rider pedals and gives proportional assist. Throttle-on-demand is included, and both locking e-brake levers cut off the motor.
