Setup and Installation
1. Mount the Bicycle Computer
- Attach the handlebar/stem mount to your bicycle's handlebar or stem using the provided zip ties. Ensure it is securely fastened and positioned for easy viewing.
- Slide the BC10.0 computer unit onto the mount until it clicks into place.
2. Install the Speed Sensor and Magnet

- Rotate the wheel to verify that the magnet passes the sensor correctly and consistently.
3. Initial Configuration
Upon first use or after battery replacement, you may need to configure basic settings:
- Wheel Size: Accurate speed and distance readings depend on correct wheel size input. Refer to your bicycle's tire sidewall for the ETRTO or ISO size, then consult the manual's appendix or online resources for the corresponding circumference in millimeters.
- Units: Select your preferred units (km/h or mph, Celsius or Fahrenheit).
- Time: Set the current time.
Use the buttons on the computer to navigate through the settings menu and adjust values. Consult the quick start guide for specific button functions during setup.

Maintenance
Cleaning:
Clean the BC10.0 and its sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the display or casing. Ensure the contacts on the computer and mount are clean and dry.
Battery Replacement:
The BC10.0 uses a CR2032 coin cell battery, providing over two years of battery life. When the battery indicator appears on the display, it's time to replace it.
- Carefully remove the battery cover on the back of the computer unit using a coin or small screwdriver.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery with the positive (+) side facing up.
- Replace the battery cover, ensuring it is securely closed to maintain water resistance.
An integrated memory chip saves all total values and settings when changing the battery, so you won't lose your accumulated data.
