The Baja Trike Electric Conversion System turns a Sun Baja Trike into an e-trike with a 500W front hub motor, a 48V 15Ah battery, and the SINET platform's color LCD and sine-wave controller. It preserves the trike's upright layout and rear drivetrain, and includes Baja-specific battery mounting behind the basket. Choose cadence or torque sensing to match your riding style. It suits Baja owners who want assist without replacing the trike, though it is a single-purpose kit rather than a universal conversion.

This is an electric conversion system made for the Sun Baja Trike. It adds electric assist while keeping the Baja's upright trike layout, rear axle and drivetrain unchanged. The 500W nominal front hub motor is built into a USA hand-built 24" fat-tire front wheel configured for the Baja, so the conversion is front-wheel drive.
The 48V 15Ah lithium-ion battery slides into the SINET battery/controller cradle, which houses the integrated sine-wave controller. Baja-specific hardware mounts the cradle behind the rear basket using the supplied support structure and mounting plate, and the basket stays usable. A Topeak handlebar extender provides a mounting spot for the 3.5" full-color LCD.
Pedal assist comes in two versions. The cadence sensor detects crank rotation and does not measure rider force. It is the simpler installation and needs no crank conversion. The torque sensor kit measures pedaling force for proportional assist. It replaces the Baja's one-piece crank with a three-piece crankset, and installation requires removing the original crank, drilling a 3/8-inch cable-routing hole through the bottom bracket shell, and using specialized bicycle tools and mechanical experience.
