Details
The Surface604 Boar Electric Fat Bike is the “Sport Utility” of bikes. The Boar is the one bike that could take you anywhere, in any season. A bike that can let you bring what you want. The Boar is fun to ride and so versatile that the second car would just sit in the driveway collecting dust. Or, even better, the Boar can replace the car altogether.
Review of 2020 model – 2022 model has some changes, new video coming soon
2019 Surface604 Boar Hunter Fat eBike Video Review and Ride Test
Powerful 500W Motor
The Boar comes equipped with a 500W hub motor
that is extremely powerful (peaks at 750W).
With a torque sensor and throttle on demand,
the Boar is well suited to carry heavy loads and is often referred to as the pickup truck of bikes.
Geared for performance - we paired all that power
with an industry-leading 12mosfet 25A controller, so
Boar unmatched torque and speed.
Watch out for other riders as you zip pass them.
Whisper Smooth Torque Sensing Pedal Assist
Because an electric bike is only as good as it’s power distribution.
Precision torque sensing performance at 104 cadence pulses per revolution; 1,000 torque samples per second.
Boar’s incredibly smooth torque sensor knows how hard
you’re pedalling down to the microsecond and matches it with proportionate power.
Custom drop out design delivers whisper smooth torque
sensor sensation at any assist level.
In fact, you’ll swear it’s as smooth as a mid-drive motor.
Gone are the days of simple cadence sensors!
Redesigned Cockpit
Now with an extra-large colour LCD display to show all vital information and provide added security.
SURFACE604 Color LCD Display with Micro USB Jack
Bigger display: 3.5" for 2021 vs. 3.2" for 2020.
Set a passcode and the bike won’t start without it, just like your phone.
