It attaches to the crank arm or wheel hub using the included mounting accessories, with a universal design that fits most bike types; a simple rotation lets you toggle between speed and cadence modes, with LED indicators showing your current mode at a glance.

Most sensors in this category use a small magnet mounted on the spoke or crank arm that triggers a reading each time it passes the sensor; check the included accessories and installation guide for your specific mounting setup, since exact magnet requirements can vary between speed and cadence modes.

The sensor is built for outdoor cycling use and general weather resistance suits regular Indian riding conditions, though as with any electronic accessory, we'd recommend wiping it dry after very heavy rain and avoiding submerging it in water to protect the internal electronics and battery contacts over the long term.
