Temperature in Sight
People who spend time outdoors want to know what the weather is like. The BC 12.0 WR computer is equipped with a built-in thermometer and always accurately displays the current temperature.


Stable data transmission
Thanks to the direct wired connection of the counter to the transmitter, the speed measurement proceeds without any interruptions. The battery for radio transmission is unnecessary in the case of the BC 12.0 WR model, and your bike computer works for years without the need for battery replacement.
Using with 2 bikes
Which bike will you choose today? Trekking bike, city bike, or maybe a racing bike? If you use different bikes, you can easily use the BC 12.0 WR computer on your second bike. After a one-time setup, you can select the currently used bike on your bike computer. For mounting on the second bike, you need an additional holder. You can find this holder in the SIGMA online store.


Factory pre-programmed tire sizes
Just a few clicks and you can hit the road. Thanks to the factory pre-programmed tire sizes, setting up the BC 12.0 WR computer is effortless: from a small children's bike to a bike with 29" wheels. There is also the option to enter the tire circumference with millimeter precision.
Monthly Statistics
The end of the trip does not mean the end of work for the BC 12.0 WR computer. This bike computer shows you your statistics from the last twelve months. You can read the total distance and riding time in them. Thanks to this “training log,” you can compare your monthly activities.


Large Backlit Display
The compact design of the BC 12.0 WR bike computer fits perfectly on a sports bike. Compared to its predecessor, the display has been enlarged to 31 x 41 mm. This allows for even larger, very readable digits while riding. This smart bike computer is equipped with a backlight, enabling easy reading of values even in the dark. The current speed is continuously displayed in the BC 12.0 WR model, and the second value can be individually selected.
Easy to Use
The BC 12.0 WR bike computer can be configured and intuitively operated using three buttons. With the two lower buttons, you can conveniently scroll through individual functions, and the menu button will take you to settings and monthly statistics. The BC 12.0 WR is easy to use yet versatile bike computer! Practical solution: thanks to the integrated start/stop function, your SIGMA ORIGINAL computer starts measuring automatically when you begin riding, while the measurement is paused when you take a break or the route has ended.


Wired Mounting
The BC 12.0 WR computer mount can be quickly installed using two zip ties on the handlebars or its bracket. The speed transmitter is also mounted in the same way. The computer receives all necessary data via the wire. The bike computer can always be removed, conveniently stored, and just as quickly reattached to the bike.
Order and perfect visibility:
Overclamp Butler mount
You can also mount the BC 12.0 WR computer to your bike using the SIGMA Overclamp Butler mount. It is available as an accessory in physical or online stores. This mount provides space and order on the handlebars and optimal visibility of the device. The BC 12.0 WR computer can be secured against theft with a screw. The Butler mount fits handlebars with diameters of 31.8 and 35 mm.


Long Butler Mount for a sporty sitting position on a bike
The Long Butler Mount provides a greater distance of the device from the handlebars – which is beneficial when riding in a sporty position on a bike. This mount can be easily attached to handlebars with a diameter of 25.4 or 31.8 mm. In this case, it is also possible to secure the bike computer against theft with a screw. The Long Butler Mount is available as an accessory in the online store and physical stores.
Records Your Multi-Day Trip
The BC 12.0 WR computer accurately measures the time spent cycling and the distance covered during that time. This allows you to conveniently track distance and riding time during multi-day cycling trips.


Service function, reminding about bike inspection
A bike requires regular service inspections. Regular inspections reveal defects in brakes, chain, or tires. Thanks to the BC 12.0 WR service interval, it reminds you to conduct a bike inspection after 750 kilometers. The service interval is therefore an important function for your safety. Information about the recommended service will appear five times when the device is turned on.
Reliable and economical
One button cell battery (CR 2450) powers your BC 12.0 WR computer for over two years without the need for recharging. During battery replacement, the integrated chip with memory saves all cumulative values and settings.


Waterproof and weather-resistant
The BC 12.0 WR wireless computer is waterproof and handles all weather conditions during all bike adventures.
Language Genius
The BC 12.0 WR computer is a small language genius: whether it's English, German, French, Italian, Spanish, Dutch, or Polish. On the full-text display, you can choose one of seven languages.
