This bicycle computer is designed to measure and display specific data on the bicycle (e.g. time, riding time, 

distance travelled). A magnet is mounted to the front wheel of the bicycle and a speed sensor is attached 

to the rigid fork. The speed sensor detects the rotations of the wheel and sends impulses to the bicycle 

computer. A tachometer and stopwatch are integrated into the bicycle computer. The bicycle computer and 

its accessories are only designed for use on a standard bicycle. Mounting and operating the device on 

another type of vehicle, e.g. a motorbike is not permitted! The product is only intended for private use. It is 

not designed for commercial use. The product is weatherproof.
