Sigma BC 8.0 Wireless Ciclocomputador

For riders who prefer a clean cockpit without cables, the Sigma BC 8.0 Wireless bike computer delivers essential ride data through a reliable analog transmission system. Unlike many entry-level wireless units that compromise on durability, this model carries an IPX8 waterproof rating, so it survives heavy rain and even brief submersion. The tool-free mounting keeps installation simple, and the large segment display remains easy to read at a glance.

Highlights

• Wireless ATS transmission – no cables between sensor and head unit
• Eight core functions: current, average, and maximum speed, trip distance, total distance, ride time, total ride time, and clock
• IPX8 waterproof – fully sealed against continuous immersion
• Tool-free mounting with predefined tire sizes for quick setup
• Long battery life: up to 2 years for the computer, 1.5 years for the transmitter

In daily use

The BC 8.0 Wireless starts and stops automatically, so you never forget to record a ride. The display shows your current speed prominently, while a press of the button cycles through average speed, maximum speed, trip distance, and ride time. Total distance and total ride time are stored permanently, even when you change the battery. The clock function is available in 12- or 24-hour format. With seven language options (German, English, French, Italian, Spanish, Dutch, and Polish), the setup menu is easy to navigate. The wireless transmitter mounts on the fork and sends speed data to the head unit without interference from other devices.
