A complete rear-wheel electric conversion kit for compatible TerraTrike recumbent trikes. It pairs a 500W nominal rear hub motor with a 48V 15Ah battery, an integrated sine-wave controller, and a 3.5-inch color SINET LCD with USB charging, diagnostics and programming. You pick the wheel size, freewheel speed and either cadence or bottom-bracket torque sensing to match your trike. It suits owners who want pedal-assist range and hill help without replacing their trike, and it is a more configurable, sensor-choice kit than fixed single-option hub conversions.

This is a rear-wheel electric conversion system for compatible TerraTrike recumbent trikes. It is built on the SINET platform and includes a 500W nominal rear hub motor, a 48V 15Ah lithium-ion battery, an integrated sine-wave controller, a 3.5" full-color LCD, a thumb throttle and locking e-brake levers. The rear motor wheel is hand-built in the USA.
The rear wheel comes in 20", 24" or 26" sizes with a 7-, 8-, 9- or 10-speed freewheel, so it can be matched to the trike's rear wheel and drivetrain. Pedal assist is either a cadence sensor or a bottom bracket torque sensor. The cadence sensor detects crank rotation, does not measure rider force, and is the simpler installation. The torque sensor measures how hard you pedal and gives proportional assistance.
The system is not compatible with TerraTrike Rover models, trikes with internal gear hubs (IGH), or rear thru-axle configurations. The motor uses a 10 mm flat bolt-on axle, so the rear dropouts must be compatible.
