Convert Your HP Velotechnik Scorpion to Electric

The E-BikeKit™ Scorpion Conversion Kit includes specialized components selected specifically for HP Velotechnik Scorpion models to ensure proper fit, drivetrain alignment, and safe handling.

Power comes from a rear 500W internally geared hub motor featuring a 5:1 planetary gear reduction and internal clutch. This design provides excellent low-speed torque, strong hill-climbing ability, and zero drag when pedaling without power.

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 extend range while maintaining a quieter, more discreet appearance.

Pedal-assist compatibility note:
Some newer Scorpion models use external-bearing bottom brackets, which require special PAS components. The default configuration is a left-side PAS sensor for square-taper bottom brackets. If your trike uses an external-bearing crankset, please contact us with photos before ordering so we can supply the correct PAS hardware.

Who is this kit for? This system is ideal for riders seeking high efficiency, lighter weight, strong starting torque, and smooth performance on a recumbent trike. The total system load limit is 300 lbs. Riders exceeding this should consider a heavy-duty system instead.
