How to change speed units in the My SmartBike app and on a Pulsar display
The iWoc shows no numbers; units are set in the app and apply to the app, the Pulsar display and recorded rides.
Step by step
- Open My SmartBike and tap the profile icon.
- Settings > 'Units' > 'Metric' or 'Imperial'.
- Return to the bike screen; speed and range update.
- Pulsar One / Two: the display follows the app setting after the next connection; without the app hold the Pulsar's centre button for 2 seconds > 'Units'.
Tip: Range in the app is in the same unit and is calculated from the last 10 km, so it moves a lot at first.

Still stuck? Take a photo of the display and show it to a local e-bike workshop. Bring the bike's system name (e.g. Bosch Performance Line CX) and the exact code; that saves diagnostic time and money.
