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 unmatched torque and speed.
Watch out for other riders as you zip pass them.
