The Surface604 Quad is an electric mountain bike that’s been engineered to ride light to medium level off-road trails, with looks to back it up. The torque sensor and a vibration free hub motor provide the rider with smooth-engaging pedal assist, and enough power to flatten steep hills.

We found the Quad to be slightly more aggressive than the Surface604 Shred we reviewed, with better tires, better saddle, and slightly more aggressive geometry. As such, it will handle adventuring on off-road trails a little better than the Shred.All in all, if you want to explore for miles on both paved and unpaved trails, commute to work, and you want your ride to catch peoples eye, check out the Surface604 Quad.
