Surface 604 Rook

A step-through electric bike designed for cruisers and commuters looking for comfort. The Rook features a powerful 500w motor with a 48v 14ah battery and comes fully-loaded with every feature needed to make riding effortless including a suspension fork, adjustable stem, built-in rear rack, front and rear fenders, and LED lights.

The Rook 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.

Precision torque sensing performance at 104 cadence pulses per revolution; 1,000 torque samples per second.
Rook'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!

Watch out for other riders as you zip pass them.
