Surface 604 Electric: Boar Explorer

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 pedaling 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!
