The E-BikeKit Eco-Tad is a conversion system built specifically for the Sunseeker Eco-Tad SX tadpole trike. It bundles a US hand-built 20-inch rear motor wheel with a 7-speed freewheel already installed, an integrated SINET controller in the battery cradle, a 3.5-inch color SINET LCD, a 48V 15Ah lithium-ion battery and a 3A charger. Buyers pick cadence sensing or bottom-bracket torque sensing; throttle-on-demand comes with either. It suits Eco-Tad SX owners who want electric assist without replacing the trike, and the torque-sensor option gives more natural, effort-proportional power than the cadence version.

This conversion kit turns the Sunseeker Eco-Tad SX tadpole trike into an electric trike. It is configured specifically for that model. It includes a USA hand-built 20-inch rear motor wheel with an installed 7-speed freewheel, a 48V 15Ah lithium-ion battery, and a 3A charger.
The SINET system pairs the controller, display, pedal-assist input, throttle, brake cutoffs, motor connection, and battery interface. The controller is built into the battery cradle. A 3.5-inch color LCD shows system and ride information and has a USB-C charging port. The electrical connectors are matched and waterproof.
Pedal assist comes in two types. The cadence sensor starts motor assistance when the cranks turn. The bottom bracket torque sensor measures rider effort and gives proportional assistance. A thumb throttle works with either type. Both e-brake levers cut off the motor. Estimated range is about 15 to 45 miles, depending on conditions.
