The Sigma BC 8.0 ATS (also designated BC 8.0 WL) represents the advanced entry point into the world of wireless bike computers from Sigma Originals. Compact, reliable and completely wireless thanks to ATS technology (coded analog radio transmission), this durable companion brings together the eight essential functions that every cyclist needs, whether for daily commutes, family rides or multi-day tours.

Eight essential functions for complete tracking

• Current speed: Always displayed at the top of the screen for immediate control
• Average speed: Automatic calculation of your pace over the entire route
• Current / average speed comparison: Signature function of the BC 8.0 with arrow indicator — up arrow if you are riding faster than your average, down arrow if you are slowing down, no arrow if you are at average pace
• Trip distance: Mileage of the current trip
• Total distance: Cumulative odometer to track your kilometers over the long term
• Trip time: Duration of your current ride
• Total time: Cumulative time spent in the saddle
• Clock: 12h or 24h display

ATS wireless transmission — Zero cables, maximum reliability

The ATS technology (coded analog radio transmission) developed by Sigma eliminates all unsightly wiring. A speed transmitter mounted on the fork continuously measures and transmits data with each wheel rotation, without interference, over a range of up to 70 cm. Installation is quick thanks to the supplied cable ties, and the computer is easily removed from the mount for storage.

Optimal ergonomics and readability

With its 31 × 39 mm screen featuring large digits, the BC 8.0 offers perfect readability even while riding. The dual-zone design permanently displays current speed at the top and the selected function at the bottom. A single large button allows easy switching between different data — safe and intuitive operation, even with one hand.

Simplified and multilingual setup

The BC 8.0 offers full text display in 7 languages (French, English, German, Italian, Spanish, Dutch, Polish). Wheel size adjustment is done either via predefined dimensions ranging from 16-inch children's bikes to 29-inch mountain bikes (700C included), or by precise manual entry of the circumference in millimeters.

Exemplary resistance and battery life

Certified IPX8, the BC 8.0 is protected against prolonged immersion — no worries in the rain or when crossing fords. The replaceable CR 2032 button cell (supplied) powers the computer for more than two years. When changing the battery, all values and settings are preserved. The automatic start/stop function (1-hour delay) optimizes battery life by detecting your breaks.

Compatibility and maintenance

The BC 8.0 ATS is UFSB compatible (Universal Firmware for Sport Computers), which allows the dealer to adjust the maintenance interval via the Sigma docking station. Ideal for cyclists looking for an affordable, reliable and comprehensive wireless computer, the BC 8.0 suits both beginners and regular cyclists who want essential tracking without complications.
