Suunto Bike Sensor measures cycling cadence, speed and distance. The sensor is great for indoor training as well as mountain biking and other cycling environments where GPS reception can be difficult. The easy-to-install sensor is compatible with sports watches and mobile apps that support Bluetooth Smart or ANT+.
Please note that Suunto Bike Sensor is not compatible with the following Suunto Ambit models: whole 1st generation, Ambit2 R and Ambit3 Run; Suunto Quest and M-Series watches.
