Important Information

Installing this chip will result in inaccurate readings on your display or flow app when using tuning mode. 

The speed readings can be easily converted if you wish. Above 22kmh, riders will need to ignore the first digit and use second digit and decimal place. You’ll then need to subtract 20kmh from the reading. Here’s some examples;

26.0kmh displayed = 40kmh Actual Speed 

25.5kmh displayed = 35kmh Actual Speed 

25.0kmh displayed = 30kmh Actual Speed

We encourage riders to use one of the free third party tracking apps like Strava or Kammoot to track rides accurately. 

Prior to installing the chip. Automatic updates must be switched off in the flow app. If you plan to update your bike’s software, always remove the chip beforehand. 

The connections on the motor are very delicate so please take care when installing or removing the chip
