Spark 3, with speed sensor giving wrong speeds

Hi,
I use my Tomtom spark 3 connected toy tomtom speed and cadence sensor indoors (Turbo) and have the wheel size set as per the instructions. My 700x25 is roughly 2100 wheel size. When I'm on the road my average speed is 18mph but on the Turbo 11.5mph. have I set something wrong ??

    I would not go with roughly. You need to get a tape measure or string and measure the actual circumference of the wheel. The specs for wheel size can vary greatly. You also need to make sure you have the sensors placed properly, with the proper spacing.

    I hope this helps answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
