BB-integrated Torque Sensor 2.0

This type of sensor is based on measurement of BB axle deflection. With no specific mounting angle required, it can be applied in mid-drive, though the chain ring/crank arm has to be customized. Its dual torque sensing offers 32 pulses of signal per cycle, which ensures signal continuity.

7Signal pulse of one full forward revolution ofBB axle32
8The output pulse duty ratio D50%
9Safety complianceEN14764
10Working temperature-20 - 70℃

Note: 4 standard BB widths: 68mm (BB axle length 148mm), 73mm (BB axle length 153mm), 84mm (BB axle length 156mm) and100mm (BB axle length 167mm), while other sizes are customizable.

There are 2 modes of cadence sensing output, one is the dual channel hall signal output; the other is single channel signal output where there’s pulse signal output during forward rotation and no pulse signal output during backward rotation (low-level output)
