The Surface604 Quad Electric Mountain Bike is 100% designed and engineered in Canada. These are high-performance electric bicycles with hydro-formed frames, entirely custom designed and constructed for a premium e-mountain bike riding experience.
Featuring a powerful 500W (750 peak) Bafang Geared Hub Brushless Motor and an industry-leading 12mosfet 25A controller, so Surface 604 e-bikes deliver unmatched torque, speed and reliablilty.
But unlike cheaper cadence-sensor driven ebikes that lurch and then suddenly drop out, Surface604 electric bikes feature precision torque-sensors for a smoother and more natural feeling ride.
Although Surface 604 bikes are also available with smaller 672wh batteries, we prefer to stock the longer range 960wh batteries for in-store purchases.
- 48V20ah (960wh) 5000mah cell size (Same as in Tesla)
- Samsung Cells 21700, Made in Korea with external charging USB Plug
- Range up to 65 Miles (105 Kms), Weight: 10.23 LBS (4.65 KG)
Whisper Smooth Torque Sensing Pedal Assistance
So long jumpy cadence sensors – an electric bike is only as good as it’s power distribution.
Surface604 electric bikes use a frame-mounted torque sensor system that monitors 104 cadence pulses per revolution and 1,000 torque samples per second.
This hyper-accurate torque-sensing system translates into seamless proportional pedal assistance from a 500 watt continuous / 750 watt peak power Bafang motor that ramps up when you actually need it and then fades off just as seamlessly.
