Boar Explorer
Powerful 500W Motor
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
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!
