They are also calibrated individually to an accuracy of +/-1.5% so that riders can trust they are receiving a real measurement and not an estimation.

- Wirelessly upgradable firmware
- LED indicator displays battery level at startup (with no need for connect to an app) and confirms successful zero reset
