Yes. Although your Pulse will detect some movement when you’re cycling, it isn’t able to detect every turn of the pedals. Please wear your Pulse when cycling. Also enter the distance you cycle into the bike field on your Step Entry page in order to be fully rewarded for your time in the saddle.
When cycling the Pulse should not be worn on the feet or lower legs. As close to the hips as possible or clipped to a pocket or backpack is advised.
