Surface 604 Colt

World class 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 pedaling down to the microsecond and matches it with proportionate power.

Custom drop out design delivers whisper smooth assist at any level.

BAFANG 48V 500W electric motor purpose built for speed and power. Enjoy the quiet and consistent power distribution at any speed.

Geared for performance - we paired all that power with an industry-leading 12mosfet 25A controller giving the Colt unmatched torque and speed.

Leave other riders envious as you effortless fly past.
