Our take on the Kit - X3 AX

This is a complete electric conversion system built specifically for the X3 AX trike, using E-BikeKit's SINET platform. It bundles a USA hand-built 20-inch front hub motor wheel, a 48V 15Ah battery, an integrated controller in the battery cradle, a color LCD with USB charging and model-specific mounting hardware. Buyers choose cadence sensing for simple rotation-triggered assist or a bottom bracket torque sensor for smoother, effort-proportional power, and a thumb throttle works with either. It suits X3 AX owners who want a matched, plug-in conversion rather than a universal kit, and it is rated for total loads up to about 300 lb.

About the Kit - X3 AX

This kit converts the X3 AX trike into an electric trike using the SINET platform. It is configured specifically for the X3 AX and includes a USA hand-built 20" front motor wheel with a 500W nominal brushless hub motor.

The controller is built into the battery cradle, and the battery connects directly to it. The system also includes a 3.5" color LCD with a built-in USB charging port, a thumb throttle, and locking e-brake levers that cut off the motor. Matched waterproof connectors join the electrical components.

Pedal assist comes in two types. The cadence sensor activates motor assistance when crank rotation is detected. The bottom bracket torque sensor measures rider effort and gives proportional assistance. Throttle-on-demand works with either type. Recommended total load is up to approximately 300 lb.

Questions and answers

What is included in the kit?
The 20-inch front motor wheel, integrated SINET controller, 3.5-inch color LCD with USB port, 48V 15Ah battery, 3A charger, battery cradle, thumb throttle, locking e-brake levers, wiring and X3 AX-specific mounting hardware.
Should I choose cadence or torque sensing?
Cadence assist switches on when the cranks turn, which is simple and predictable. The bottom bracket torque sensor measures your effort and adds power proportionally, giving a smoother, more natural ride.
Does the throttle work with pedal assist?
Yes. The thumb throttle is included with either the cadence or the torque-sensor configuration.
How much weight can it handle?
E-BikeKit recommends the system for total loads up to about 300 lb, including rider and cargo.
Will it fit a trike other than the X3 AX?
No. The mounting hardware and wiring are made for the X3 AX, so it is not a universal kit.

A 500W nominal front hub motor in a 20-inch wheel built in the USA.
