Powerful 500W Motor
The Colt comes equipped with a 500W hub motor that is extremely powerful (peaks at 750W).
With a torque sensor and throttle on demand, the Colt is great for those that could benefit from an extra boost to make it up the hill.
Geared for performance - we paired all that power with an industry-leading 12mosfet 25A controller, so Colt delivers unmatched torque and speed.
Watch out for other riders as you zip pass them.

Whisper Smooth Torque Sensing Pedal Assist
Because an electric bike is only as good as it’s power distribution.
Precision torque sensing performance at 104 cadence pulses per revolution; 1,000 torque samples per second.
Colt’s incredibly smooth torque sensor knows how hard you’re pedalling down to the microsecond and matches it with proportionate power.
Custom drop out design delivers whisper smooth torque sensor sensation at any assist level.
In fact, you’ll swear it’s as smooth as a mid-drive motor.
Gone are the days of simple cadence sensors!
