Kit - X3 AX

This X3 AX–specific E-BikeKit conversion system is designed to convert the X3 AX trike into a clean, efficient, and responsive electric trike using the current-generation SINET™ platform.

The system includes a USA hand-built 20″ front motor wheel, integrated SINET™ controller, 3.5″ color SINET™ LCD with USB charging port, 48V 15Ah lithium-ion battery, 3A charger, battery cradle and model-specific mounting hardware, thumb throttle, locking e-brake levers, matched wiring, and X3 AX–specific installation components.

• Configuration developed specifically for the X3 AX trike
• USA hand-built 20″ front motor wheel
• 500W nominal front hub motor
• Integrated controller housed in the battery cradle
• 48V 15Ah battery and 3A charger included
• Choice of cadence pedal assist or bottom bracket torque sensing
• Throttle-on-demand included with either pedal-assist option
• Model-specific battery mounting hardware included
• Recommended for total loads up to approximately 300 lb

Choose your pedal-assist system:

• Cadence Sensor: Activates motor assistance when crank rotation is detected.
• Bottom Bracket Torque Sensor: Measures rider effort and provides a smoother, more natural, proportional level of motor assistance.

The pedal-assist type is the only selection required. The 20″ motor wheel, integrated controller, battery, charger, battery mounting system, LCD, throttle, wiring, locking e-brake levers, and model-specific installation hardware are included with every X3 AX conversion system.

Who’s it for? Dealers looking for a complete, model-specific X3 AX conversion system with matched SINET™ components, a professionally built motor wheel, and direct technical support.

This system includes the battery, charger, integrated controller, 20″ motor wheel, and X3 AX–specific mounting and installation components. The only selection required is the pedal-assist type: cadence or bottom bracket torque sensing.

X3 AX Conversion System Components:

This conversion system is designed specifically for the X3 AX trike.

• Designed for a 20″ front motor wheel
• Requires standard 100 mm front fork spacing
• Requires compatible conventional slotted front dropouts
• Includes X3 AX–specific battery mounting hardware
• Recommended for total loads up to approximately 300 lb, including trike, rider, and cargo

The bottom bracket torque sensor is designed for a 68 mm square-taper bottom bracket. Confirm bottom bracket compatibility before ordering the torque-sensor version.

Trikes that have been modified or differ from the standard factory configuration may require additional parts or installation adjustments.

The X3 AX conversion system uses matched SINET™ components and connectors to simplify installation on a compatible X3 AX.

• Install the 20″ front motor wheel into the 100 mm front dropouts
• Install the supplied torque arm(s) and properly secure the axle hardware
• Install the X3 AX–specific battery mounting hardware
• Mount the integrated battery/controller cradle securely
• Install and secure the included 48V 15Ah battery
• Install the SINET™ LCD, thumb throttle, and locking e-brake levers
• Install the selected cadence or bottom bracket torque sensor
• Route and secure the SINET™ wiring harness, motor cable, and sensor extension cable as required
• Verify axle hardware, torque-arm placement, brake operation, steering clearance, battery mounting, and cable routing before riding

If installing the Bottom Bracket Torque Sensor, confirm compatible 68 mm square-taper bottom-bracket fitment and follow the required torque-sensor cable-routing procedure.

Professional bicycle-shop installation is recommended when the installer is not experienced with bicycle wheels, brakes, electrical systems, torque arms, or bottom bracket service.
