Kit - Eco-Delta

This Eco-Delta–specific E-BikeKit conversion system is designed to convert the Sunseeker Eco-Delta SX delta trike into a clean, efficient, and responsive electric trike.

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 mounting hardware, throttle, locking e-brake levers, matched wiring, dual torque arms, and Eco-Delta–specific installation components.

• Configuration developed specifically for the Sunseeker Eco-Delta SX
• USA hand-built 20″ front motor wheel
• 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
• Estimated range of approximately 15–45 miles depending on conditions
• 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 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 Eco-Delta conversion system.

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

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

This conversion system is designed specifically for the Sunseeker Eco-Delta SX delta trike.

• Designed for a 20″ front motor wheel
• Requires standard 100 mm front fork spacing
• Includes two torque arms for secure axle retention
• Includes locking parking-brake levers with motor cutoff
• Includes model-specific underseat 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 Eco-Delta conversion system uses matched SINET™ components and connectors to simplify installation on a compatible stock Eco-Delta SX.

• Install the 20″ front motor wheel into the 100 mm front dropouts
• Install both supplied torque arms
• Torque the axle nuts to 35 ft-lb
• Mount the integrated battery/controller cradle securely beneath the seat
• 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
• Verify axle-nut torque, torque-arm placement, brake operation, steering clearance, and cable routing

Proper installation of both torque arms, correct axle-nut torque, secure battery mounting, safe cable routing, and proper brake adjustment are essential for safe operation.

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