SURFACE 604 - QUAD 2021
The Quad is outfitted with a high-speed Bafang electric mountain bike specific 500W hub motor with a throttle that is extremely powerful (peaks at 750W).
A major feature that separates the Quad from the pack of other eMTBs on the market, is the MAXXIS REKON+ 27.5” x 2.8” Skinwall tires (3C, Exo casing tech) that the bike comes stock with.
With a larger rubber patch contacting the ground, the plus size tires add traction and mute small bumps, giving the rider added confidence, superior performance and a more comfortable ride.
The Quad comes standard with a number of features that were added to make the riding experience for comfortable.

Good rugged bike, big tires but not fat tires for better battery life. Definitely has power and the torque sensor make this bike seem very real and natural. Added a suspension seat post and its a lot of fun to ride.
I am 5’8” and weigh 196 lbs just so you have a reference point. I purchased a M/L Quad by Surface 604 because I was looking for something a little faster then the Moscow Plus by NCM that I previously owned! I have 420 KMS on the Quad and I can say that it is amazing! Although it is a hub motor, it is very very quiet and has a smooth transition of power from the motor to the pedals! You almost don’t even feel it, you think wow this is easy. Surface 604 uses a torque sensor which is activated by how hard you pedal, it feels really natural and allows me a 65 year old to enjoy those hills instead of being intimidated by them. Don’t even get me started on the brakes... all as I can say is be careful... they are squeal free and instant stopping, you ride with more confidence. The bike is a true class 3 so it will go 45 KMS an hour with throttle only, i love that. So far the product and service from the dealer has exceeded my expectations. Thank-you EBIKES Calgary and Surface 604. Lastly I would like to thank Erin at EBIKES Calgary for all her assistants with this purchase and Mitchel at Surface 604 for his technical help.
