- maximum speed
- comparison of current speed with average
- distance traveled
- total distance traveled
- time traveled
- total time of travels
- current temperature
- clock

Temperature in sight
People cycling outdoors want to know what the weather is like. The BC 12.0 WR computer is equipped with an integrated thermometer and always accurately shows the prevailing temperature.


Stable data transmission
Thanks to the direct wired connection of the counter to the transmitter, the speed measurement proceeds without any interruptions. A battery for radio transmission is unnecessary in the case of the BC 12.0 WR model, and your bicycle computer works for years without the need for battery replacement.
Usage with 2 bikes
Which bike will you choose today? A trekking bike, a city bike, or perhaps 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 bicycle computer. For mounting on the second bike, you need an additional mount. You can find this mount 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 hassle-free: from a small children's bike to a bike with 29" wheels. There is also the option to enter the tire circumference with millimeter accuracy.
Monthly statistics
The end of the trip does not mean the end of work for the BC 12.0 WR computer. This bicycle computer shows you your statistics from the last twelve months. You can read the total distance and riding time. Thanks to this “training diary,” you can compare your monthly activities with yourself.


Large display with backlight
The compact design of the BC 12.0 WR bicycle computer fits perfectly on a sports bike. Compared to its predecessor, the display has been enlarged to 31 x 41 mm. Thus, it can display even larger, very readable numbers while riding. This smart bicycle computer is equipped with backlighting, allowing for easy reading of values even in the dark. The current speed is continuously displayed in the case of the BC 12.0 WR model, and the second of the displayed values can be selected individually.
Easy operation
The BC 12.0 WR bicycle computer can be configured and intuitively operated using three buttons. With the two lower buttons, you can conveniently scroll through the 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 bicycle computer! A practical solution: thanks to the integrated start/stop function, your SIGMA ORIGINAL computer starts measuring automatically when you start riding, while the measurement is paused when you take a break or the route has come to an end.


Wired installation
The BC 12.0 WR computer mount can be quickly installed using two zip ties on the handlebars or its stem. The speed transmitter is also mounted in the same way. The computer receives all necessary data via the wire. The bicycle computer can always be removed, conveniently stored, and just as quickly reattached to the bike.
Order and excellent 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 the 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 the bike. This mount can be easily attached to handlebars with a diameter of 25.4 or 31.8 mm. In this case, the bicycle computer can also be secured 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 on the bike and the distance covered during that time. This way, you can conveniently measure the 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, chains, or tires. Thanks to the service interval of the BC 12.0 WR, it reminds you to conduct a bike inspection after 750 kilometers. The service interval is therefore an important function for your safety. The information about the recommended service will appear five times after turning on the device.
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. When replacing the battery, the integrated chip with memory saves all total values and settings.


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