I have a garmin 735 and it doesn’t record a cycling vo2 max. I can manually put my own figure in but it won’t automatically detect as it does with running. I have a watt bike with does have the correct power metre and communicates effectively with the watch to measure an indoor cycle. My husband has the same watch and his displays a cycling VO2, so I have no idea why mine won’t do the same. Any advice or suggestions very welcome.
