The wireless BC 5.0 WL is an introduction to the world of SIGMA ORIGINALS cycling computers. Whether used by commuters, recreational cyclists, or children, the computer's five functions reliably provide cyclists with key data, such as speed and distance. It's easy to use, clear, compact, and affordable. Key features Overview of the most important functions The smallest, most compact SIGMA bike computer displays information such as speed, daily distance, total distance, ride time and time – five basic functions that cyclists like to have at their fingertips. Wireless data transmission SIGMA's wireless (WL) coded radio data transmission eliminates the need for cables. A radio transmitter attached to the fork continuously and uninterruptedly transmits the bike's speed to the BC 5.0 WL's receiver. Compact and readable display The BC 5.0 WL's large 27 x 35 mm display indicates your current speed and clearly presents other important data. The odometer display is characterized by simplicity: four different symbols in the bottom row indicate the selected function. This makes reading the bike computer's readings child's play. Easy to use Configuring and operating the BC 5.0 WL model is child's play – with one button you can select the function you need at any time. Weather-resistant, with a long-lasting battery The BC 5.0 WL cycling computer is waterproof and operates reliably in a variety of weather conditions, ensuring it's always ready to use. Cyclists also don't need to worry about its battery life. The integrated, replaceable button cell battery (CR 2032) powers the BC 5.0 WL for over two years. Other features Multi-day routes The BC 5.0 WL also measures ride time and distance on longer bike rides. This makes it easy to track the entire distance of a multi-day cycling holiday. Easy assembly The handlebar mount for the BC 5.0 WL and the speed sensor can be quickly mounted on the bike using the cable ties included in the set, while the bike computer itself can be conveniently removed and stored in a pocket.
