Numerous features, easy operation

The BC 23.16 STS not only scores with its many features but also by its ease of use. Whether bike functions, altitude functions, heights functions or laps, there is a button for each area that quickly gives you an overview.


data analysis

Including detailed data analysis with all transmitters

The BC 23.16 STS displays all the important bike, altitude and heart rate functions. An altitude profile is created just like a heart rate graph. In the altitude view you can read, inter alia, data on the current altitude, current ascent/descent, total height and the uphill/downhill altitude in metres of the current trip. Moreover the current as well as the average and maximum cadence are displayed. All necessary transmitters are included in the scope of delivery.

Enormous logging capacity

You can save up to 99 logs on your BC 23.16 STS. This results in a total log of up to 500 hours at a log interval of 20 seconds.

50 Laps - Ghost Race

50 Laps

The BC 23.16 STS can store up to 50 laps per trip. For the super fast operation there is an extra lap button. There is detailed data available for each lap that can be analysed in the lap view. You can scroll through the values of each lap or select a value and compare the laps with each other.

Ghost Race

One data set can be selected from the stored log data using the DATA CENTER, which serves as a virtual opponent for a "ghost race". On the display the rider can always see the time and route distance from the "ghost" and who is leading.



The BC 14.16, BC 16.16 and BC 23.16 models can communicate directly with an Android smartphone via NFC (near field communication). To do so, you must install the free SIGMA LINK app. For wireless data exchange, simply hold your smartphone up to the computer. The app can be used to change settings and read trip data.

The data can be transferred from the smartphone into the DATA CENTER via the SIGMA CLOUD. Conversely, it is also possible to transfer data from the DATA CENTER onto the smartphone via the CLOUD.

The free SIGMA LINK app is available in the app store and Google Play store. The NFC technology is only available for Android smartphones.

Power in watts


The BC 23.16 STS calculates your current and average performance in wattage. Thus you can always compare your performance.

Temperature display

Temperature display

All models from the BC 14.16/STS/CAD to the BC 23.16 have a temperature indicator. This shows the current temperature of your environment at all times.

Speed comparison

A comparison of the current and average speed. While cycling, a permanent comparison is made of your current and average speeds. The difference is indicated by an up or down arrow. When moving at approximately the average speed, no arrow is displayed.

Speed comparison

wheel sizes

Adjustable wheel sizes

When using two bikes, two wheel sizes can be set that are automatically (automatic only for STS) detected. To use this function, the speed transmitter must be switched to that on the second bike and the right wheel circumference for ‘bike 2’ must be set on the BC 23.16 STS.

Integrated storage chip

storage chip

Thanks to an integrated memory chip in the computer head unit, all the total values and settings are permanently stored in the device. After changing the battery, you therefore only need to reset the time.

Information on the power status

power status

All devices from BC 23.16 STS upward come with a battery status indicator. The power status of the battery in the computer head unit or STS transmitter is checked at regular intervals. If the battery is low, an early warning is displayed on the computer head unit.

Bike inspection reminder function


Thanks to the service interval, you are reminded to submit your bike to an inspection after a freely selectable number of kilometers cycled. The service interval can only be enabled/disabled and pre-configured by the retailer. The retailer can set the desired number of kilometres using the UNIVERSAL FAST SETTING BOX. The device comes with the service interval disabled.
