This rear-wheel system fits most standard bicycles and adult tricycles that use a 135 mm rear dropout.

Requirements:

• Rear dropout spacing must be 135 mm
• Frame must accept a threaded freewheel (not a cassette)
• Steel or reinforced aluminum dropouts recommended when using a hub motor

Not Compatible With:

• Internal geared hubs (IGH)
• Rear thru-axle frames
• Frames requiring cassettes instead of freewheels

Email or text photos if you'd like us to confirm compatibility before ordering.

This system installs with common bicycle tools and includes all required hardware:

• Motor wheel installs into 135 mm rear dropouts
• Controller, LCD, and wiring use plug-matched connectors
• PAS sensor mounts at the crank (left side by default)
• E-brake levers replace standard brake levers
• Torque arms must be installed and axle nuts torqued properly
• Battery must be securely mounted using an appropriate mount

Proper torque-arm installation, clean cable routing, and correct PAS placement are essential for safe, long-term operation.
