FEATURES
WHISPER SMOOTH TORQUE SENSING PEDAL ASSIST
Because an electric bike is only as good as it’s power distribution.
Shred’s incredibly smooth torque sensor knows how hard you’re pedaling down to the microsecond and matches it with proportionate power.
Gone are the days of simple cadence sensors!
Custom drop out design delivers whisper smooth torque sensor sensation at any assist level.
In fact, you’ll swear it’s as so smooth as a mid-drive motor.
