Temperature in sight
Outdoor skiers want to know what the weather is like. The BC 12.0 WR is equipped with an integrated thermometer and always shows the temperature accurately.


Stable data transmission
Thanks to the direct wired connection of the meter to the transmitter, the speed measurement takes place without any interference. A radio transmission battery is unnecessary with the BC 12.0 WR, and your bike computer will last for years without having to replace the battery.
Use with 2 bikes
Which bike will you choose today? Trekking bike, city bike or race bike? If you use different bikes, you can easily use the BC 12.0 WR on your second bike. After setting up once, you can select the bike you are currently using on your bike computer. For mounting on a second bike, you need an additional mount. You can find this holder in the SIGMA online shop.


Pre-programmed tyre sizes
With just a few clicks, you're ready to go. Thanks to the pre-programmed tyre sizes, setting up the BC 12.0 WR is easy to set up: from a small children's bike to a bike with 29" wheels. It is also possible to enter the circumference of the tire with millimeter accuracy.
Monthly statistics
The end of the tour does not mean the end of the work for the BC 12.0 WR. This bike computer shows you your stats for the last twelve months. You can read the total distance and driving time in them. With this "training diary" you can compare your monthly activities with each other.


Large backlit display
The compact design of the BC 12.0 WR bike computer fits perfectly with your sports bike. Compared to its predecessor, the display has been enlarged to 31 x 41 mm. Thus, it can display even larger, very legible numbers while driving. This smart bike computer is equipped with a backlight, which allows you to read the values without any problems even in the dark. The current speed is continuously displayed for the BC 12.0 WR, the second value can be selected individually.
Easy to use
The BC 12.0 WR bike computer can be configured and operated intuitively with three buttons. With the two bottom 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 an 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 start your ride, while the measurement is paused when you take a break or the route is over.


Mounting with a cable
The BC 12.0 WR computer holder can be quickly mounted with two cable ties on the handlebar or its bracket. The speed transmitter is also mounted in the same way. The computer receives all the data it needs via the cable. The bike computer can always be removed, conveniently stowed away and just as quickly put back on the bike.
Tidiness and excellent visibility:
Overclamp Butler Handle
You can also attach the BC 12.0 WR to your bike using the SIGMA Overclamp Butler. It is available as an accessory in stationary or online stores. This handle ensures space and order on the handlebars and optimal visibility of the device. The BC 12.0 WR can be secured against theft with a screw. The Butler mount fits handlebars with diameters of 31.8 and 35 mm.


Long Butler handle for a sporty sitting stance on the bike
The Long Butler mount provides a greater distance from the handlebars – which is beneficial when riding in a sporty position on the bike. This holder can be easily attached to a handlebar with a diameter of 25.4 or 31.8 mm. The Long Butler Holder is available as an accessory in the Internet store and stationary stores.
Saves your multi-day trip
The BC 12.0 WR accurately measures the time spent on the bike and the distance covered during that time. Thanks to this, you can conveniently measure the distance and time of the ride during multi-day cycling trips.


Service function, reminding you to inspect your bike
The bike requires regular service inspections. A regular inspection reveals defects in the brakes, chain or tires. With a service interval, the BC 12.0 WR reminds you to inspect your bike after 750 kilometres. The service interval is therefore an important feature for your safety. The recommended service will appear five times when you turn on your device.
Reliable and cost-effective
One button battery (CR 2450) without needing to charge your BC 12.0 WR with more than two years of energy. When replacing the battery, the integrated chip in the memory saves all total values and settings.


Waterproof and resistant to all weather conditions
The BC 12.0 WR wireless computer is waterproof and can handle all weather conditions on all your cycling adventures.

The BC 12.0 WR is a little language genius: whether English, German, French, Italian, Spanish, Dutch or Polish. On the full-text display, you can select one of seven languages.
