Kit - Eco-Delta

The Eco-Delta Conversion System transforms the Sunseeker Eco-Delta SX into a powerful electric delta trike using a 500W internally geared front hub motor and an optional 48V 15Ah lithium-ion battery pack.

• Special parts included specifically for the Eco-Delta SX
• Top speed approximately 20 mph at 48V
• Estimated 15–45 mile range depending on rider, terrain, and usage
• Supports both pedal-assist and throttle-on-demand

This system uses a 500–1000W internally geared motor with a 5:1 planetary reduction and internal clutch. The clutch provides zero drag while pedaling unassisted, and the geared design offers superior efficiency, better hill-climbing performance, and a lighter feel compared to direct-drive motors.

Who’s it for? Riders who want a smooth-riding, torque-rich electric assist system for the Eco-Delta SX. Recommended for total loads up to 300 lb (trike + rider + cargo).

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

• Requires standard 100 mm front fork dropout spacing
• Optimized for stable, torque-rich delta-style trike performance
• Supports total loads up to ~300 lb

Some frames may require minor adjustments based on condition or past modifications.

The Eco-Delta system installs using basic hand tools and fits directly into the 100 mm front fork spacing.

• Motor wheel installs into 100 mm front dropouts
• Controller, LCD display, and wiring use matched connectors
• PAS sensor mounts at the crank (left side standard)
• Locking parking brake levers replace stock levers
• Both torque arms must be installed; axle nuts must be torqued to 35 ft-lb
• Battery mount installs in the factory-supported locations shown in product photos

Secure cable routing and proper torque-arm installation are essential for safe, long-term performance.
