Indoor cycling

When I ride indoors on my gym's spin bike, my Forerunner says "no HR" when I scroll to the HR screen. When I sync the session with Garmin Connect afterwards, it tells me a max HR in the stats, but no average.

When I scroll through the data fields for indoor cycling when I'm away from my gym's spin bike, it does display HR. 

Could this be that I have inadvertently connected my device to the gym bike's computer? And if so, how to I disconnect it? I cannot see anything obvious on the wearable or the app.

  • If an external HR sensor is connected it will tell you that when it connects. Check the attached sensors in the sensors menu on the watch and remove any that you don't recognize.

    It could also be that you twist your wrist in a way that makes the HR to not read.

    It is very hard to say what is happening. You have to do some more tests and see at what point it happens.
