Surface 604 Rook
The everyday commuter that keeps up with you. 960 Wh, Class 3, torque-sensing pedal assist — rides like a real bike, just with 500 watts of help.
The Surface 604 Rook is the flagship high-step commuter — clean design, hidden wiring, and a dropout torque sensor that makes it feel like a real bike rather than a moped. The 960 Wh / 48V 20Ah Samsung 21700 battery is the biggest in its class, providing up to 150 km eco range. Bafang 500W geared hub motor at 65 Nm, Shimano Alivio 9-speed drivetrain, Tektro Auriga hydraulic disc brakes, SR Suntour 80mm fork. UL 2271 + UL 2849 dual certified. Built in Vancouver since 2014.
Highlights
One torque sensor design since 2020 — 20-minute repair
Surface 604 has used a single dropout torque sensor design for years. Every part is stocked, every mechanic can service it, and replacement takes 20 minutes — not a trip to a specialist dealer.
960 Wh — class-leading range
31% more than Aventon, 43% more than Lectric. Up to 150 km on eco. Commute all week on a single charge, or ride a full day of mixed terrain without range anxiety.
Clean commuter aesthetics
Internal cable routing, integrated lights, and a frame geometry that doesn't scream "e-bike." The Rook looks like a regular bike — just with more range than most vehicles.
Parts your mechanic already stocks
