Convert Your Sunseeker EZ-Tri Classic to Electric

The E-BikeKit™ EZ-Tri Classic Conversion Kit includes specialized components selected specifically for the EZ-Tri Classic platform to ensure proper fit, balance, and safe operation.

This system uses a front 500W internally geared hub motor featuring a 5:1 planetary gear reduction and internal clutch. The clutch allows zero drag when pedaling without power, while the geared design provides excellent low-speed torque and improved hill-climbing ability.

Compared to a direct-drive motor of similar power, this geared motor is lighter, more efficient, and better suited to stop-and-go riding, helping maximize range while maintaining a quiet, discreet appearance.

Who is this kit for? This system is ideal for riders who want high efficiency, lighter weight, and smooth low-speed performance on a traditional upright electric tricycle. The total system load limit is 300 lbs. Riders exceeding this should consider a heavy-duty system instead.

Battery mount upgrade: An optional battery mounting kit is available that allows the battery to be positioned neatly and securely, improving weight distribution and overall fit and finish. Select this option above if desired.
