VeloComputerTM Smart Sensor works without any magnets. It can be wirelessly configured as HUB for speed or CRANK for cadence.

HUB sensor calculates wheel motion with unmatched accuracy. It measures distance with 1" (25 mm) precision.

CRANK sensor calculates cadence and can also detect crank position with precision.

VeloComputerTM Smart Sensor is not susceptible to a shock or vibration. It works reliably everywhere on earth, maybe not on the North Pole.

NOTE: Some bikes may have a narrow gap between a crank and a chain-stay. In this case glue the CRANK sensor to your crank in the same orientation and position as shown in the video above using this mounting tape.

The same mounting tape can be used to mount the HUB sensor to a disk wheel.
