Looking for your 1st electric mountain bike? Welcome to the Surface 604 Shred – a strong performing, value-priced offering that is sure to satisfy for a good long time. We’re continually impressed with the performance that this tough and ready-to-rock rig provides.

The Bafang motor system delivers ample power via 5 levels of pedal assist and/or a manual throttle option. A sophisticated torque sensor assures a smooth rollout of the power when in pedal-assist mode. A 28 mph top speed in PAS mode is another bonus feature. Beefy hydraulic disc brakes keep the show under control. 9-speeds make for smooth pedaling transitions – essential in trail riding situations. Extra-wide tires give a commanding grip off-road yet perform impressively on pavement as well.
