Kit - HP Velotechnik

This conversion system is designed specifically for HP Velotechnik Gekko and Scorpion recumbent trikes, using a 500W internally geared rear hub motor paired with an optional 48V 15Ah lithium-ion battery pack.

• Special configuration tailored for HP Velotechnik Gekko & Scorpion models
• Top speed up to ~26 mph at 48V
• Estimated 15–45 mile range depending on rider, terrain, and input
• Supports pedal-assist and throttle-on-demand

The 500–1000W geared motor uses a 5:1 planetary reduction and an internal clutch for zero-drag pedaling. It offers excellent hill-climbing ability, higher efficiency, lighter weight, and a stealthier appearance than direct-drive motors.

Who’s it for? Riders who want lightweight efficiency, strong torque, and premium performance on HP Velotechnik trikes. Recommended for total loads up to 300 lb (rider + trike + cargo).

If you need help with a specific Gekko or Scorpion configuration:
Contact us — we will walk you through the exact PAS setup, mounting solution, and hardware needed for a clean installation.

Our mission:
Equip every dealer with the clarity and confidence to perform a clean, professional HP Velotechnik installation.

This kit is designed for most HP Velotechnik Gekko and Scorpion models.

Important Compatibility Notes:

• Rear dropout spacing must be 135 mm
• Not compatible with internal geared hubs (IGH)
• Not compatible with rear thru-axle frames
• External-bearing cranksets require special PAS components (right-side PAS sensor + split magnet ring)
• Square-taper cranksets use the standard left-side PAS system

Bottom Bracket PAS Notes:

• External-bearing BB: use PAS 12-magnet split 64/74 BCD + right-side sensor (legs may require trimming)
• Square-taper BB: standard left-side PAS installs normally

Send photos of your crankset if unsure — we will confirm compatibility and the correct PAS configuration.

This system installs using basic hand tools and includes all required model-specific extras.

• Rear motor wheel installs into 135 mm dropouts
• Controller, LCD, and wiring connect using matched plugs
• PAS installation depends on BB type (external vs. square-taper)
• MTB bar-end helps position throttle clear of shifter cables (on certain models)
• Torque arms must be installed and axle nuts torqued properly
• Battery mount must be securely installed (mount sold separately)

Correct PAS setup, torque-arm installation, and clean cable routing are essential for safe, reliable operation.
