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.

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!
