Note: standard BB width at 68mm with BB axle length to be customized. This product is granted national invention patent.

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.


1Working voltage5V
2Working currentIdd<23mA
3ZTV initial origin voltage0.7V+/-0.15V
450Kgf pull force output voltage variation(crank arm length 170mm)2.9V+/-0.15V
5Measurement range1~85N.m
6Torque signal output current Itor (note:1.5kΩand 1uF RC filter output)5mA
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)

3ZTV initial origin voltage0.7V+/-0.15V
450Kgf pull force output voltage variation (crank arm length 170mm)2.0V +/-0.15V
5Measurement range1~85N.m
6Torque signal output current Itor 5mA
7Signal pulse of one full forward revolution of BB axle32
8The output pulse duty ratio D50%
9Safety complianceEN14764
10Working temperature-20 - 70℃


Note: 4 standard BB widths are available: 68mm, 73mm, 84mmand100mm, while BB axle length varies at 118mm, 122.5mm, 127.5m and etc.

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 (namely low-level output)

BB-integrated Cadence Sensor

Its full metal body ensures high structural strength and reliability, while its cost efficiency makes it perfect for mass market application.


1Working voltage5V
2Working currentIdd<15mA
3Signal pulse of one full forward revolution of BB axle32
4The output pulse duty ratio D40%-60%
5Safety complianceEN14764
6Working Temperature-20 - 70


Note: 4 standard BB widths are available: 68mm, 73mm, 84mm and 100mm, while BB axle length is like standard bicycle BB axle and is 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 (namely low-level output)
