The E-BikeKit Electric Trike Conversion System – No Battery is configured for compatible traditional upright adult tricycles where the rider already has a suitable 48V battery. The front-wheel layout leaves the tricycle's rear axle and drivetrain unchanged.

Electric Trike Conversion System – No Battery

This current-generation E-BikeKit system replaces the legacy E-TrikeKit electronics with the latest SINET™ conversion platform. It is intended for compatible conventional upright adult tricycles using a standard 100 mm conventional slotted front fork.

This version uses an external SINET™ sine-wave controller, giving you flexibility in battery choice, battery location, controller mounting, and wiring layout.

The system uses a 500W nominal front hub motor. Because the motor is installed in the front wheel, the tricycle's existing rear axle, rear wheels, chain, and drivetrain remain unchanged.

Ordering is simple: select the front wheel size that matches your tricycle and choose either the Cadence Sensor or Torque Sensor + Crank Conversion Kit. Front dropout spacing is always 100 mm for this system.

Important: No battery or charger is included. A battery wire harness / pigtail is included for integrating a compatible customer-supplied 48V battery.

• USA hand-built front hub motor wheel in the selected wheel size
• External SINET™ sine-wave controller
• SINET™ 3.5" full-color LCD with USB charging port
• SINET™ component wiring harness
• Thumb throttle
• Left and right mechanical e-brake levers with motor cutoff and parking lock
• Motor cable
• Battery wire harness / pigtail for connecting a compatible 48V battery
• Torque arm(s), washers, zip ties, and conversion-system installation hardware as required

Your pedal-assist selection determines the components included:

• Cadence Sensor: Left-side external cadence sensor with 12-magnet split disc
• Torque Sensor + Crank Conversion Kit: SINET™ 68 mm square-taper bottom bracket torque sensor, bottom bracket adapter, three-piece cranks, pedals, and required SINET™ extension cable

Not Included: Battery, charger, and battery mounting system.

The external-controller version of SINET™ is designed for riders who want to use a compatible existing 48V battery or provide their own battery and mounting solution.

• Quiet, efficient SINET™ sine-wave motor control
• External controller for flexible mounting
• 3.5" full-color LCD with USB charging port
• Matched waterproof electrical connectors throughout the SINET™ system
• Cadence and torque-sensing pedal-assist compatibility
• Throttle-on-demand
• Motor cutoff through both e-brake levers
• Easy controller access for diagnostics or future replacement

This system is designed around standard 100 mm conventional slotted front fork dropouts. The motor is installed in the front wheel, so the tricycle's rear axle and drivetrain remain unchanged.

• Front Dropout Spacing: 100 mm
• Wheel Size: Select the front wheel diameter that matches your tricycle
• Rear Drivetrain: Remains unchanged
• Fork Type: Conventional slotted front dropouts required

Check fitment before ordering. Front thru-axle forks are not compatible. If you are unsure whether your tricycle's front fork is suitable for a hub-motor conversion, contact E-BikeKit before ordering.

Cadence Sensor

The cadence sensor detects crank rotation and activates pedal assistance according to the assist level selected on the LCD. It is an external left-side sensor and is the simpler installation option for most conversions.

• Left-side external sensor
• 12-magnet split disc
• Detects crank rotation
• Simple installation on compatible tricycles
• Does not measure rider force

Torque Sensor + Crank Conversion Kit

Many traditional upright adult tricycles use a one-piece crank that is not directly compatible with the SINET™ 68 mm square-taper bottom bracket torque sensor. The Torque Sensor + Crank Conversion Kit provides the components needed to convert a compatible one-piece-crank tricycle to a three-piece crank configuration and install the SINET™ torque sensor.

• SINET™ 68 mm square-taper bottom bracket torque sensor
• Bottom bracket adapter for a compatible one-piece-crank frame
• Three-piece cranks
• Pedals
• Required SINET™ extension cable
• Measures rider pedaling force and provides smooth, proportional assistance
• Installation requires removal of the existing crank assembly and conversion to the supplied three-piece crank components
• Installation requires a protected 3/8-inch cable-routing hole through the bottom bracket shell for the torque-sensor cable and supplied grommet

Which should you choose? The Cadence Sensor is the simpler installation and does not require converting a compatible one-piece crank system to a three-piece crank. The Torque Sensor + Crank Conversion Kit provides a more natural, proportional response and includes the torque sensor, bottom bracket adapter, three-piece cranks, and pedals required for the conversion, but installation is substantially more involved.

• 3.5" full-color display
• USB charging port
• Battery voltage and level display
• Current speed, trip meter, and odometer
• Pedal-assist level selection
• Walk-assist mode
• Error diagnostics
• Advanced programming menu

Important: A battery being 48V does not by itself guarantee compatibility. Connector type, polarity, discharge capability, battery condition, and mounting must all be appropriate for the system.

If you are unsure whether your existing battery is compatible, contact E-BikeKit before ordering. Photos of the battery label, battery connector, and mounting arrangement can help us evaluate compatibility.

• Bottom bracket shells or crank configurations incompatible with the selected pedal-assist system or crank conversion components

If you're unsure about fitment or battery compatibility, contact E-BikeKit before ordering.

Installing a front-wheel electric tricycle conversion system requires mechanical bicycle work as well as mounting and connecting electrical components. Professional bicycle-shop installation is recommended if you are not experienced with wheels, brakes, forks, battery wiring, and electric conversion systems.

• Install the motor wheel into standard 100 mm front fork dropouts
• Install the supplied torque arm(s) as required and properly tighten axle hardware
• Mount the external SINET™ controller securely
• Install the compatible 48V battery using an appropriate mounting system
• Verify battery voltage, polarity, connector compatibility, and discharge capability before connection
• Install the LCD, thumb throttle, locking e-brake levers, and selected pedal-assist system
• If using the Torque Sensor + Crank Conversion Kit, remove the existing one-piece crank assembly, install the supplied bottom bracket adapter, torque sensor, three-piece cranks and pedals, and route the torque-sensor cable through the required 3/8-inch protected exit hole
• Route wiring away from moving parts, steering components, tires, chains, and sharp edges
• Verify brake cutoffs, throttle operation, pedal assist, wheel clearance, battery connection, steering movement, and display settings before riding
