I would take it off and log the activity separately. It may log it in some fashion (mine did) but it's likely not accurate as it's not designed to do that.

I want to get back to wearing a pedometer. I have a stationary bike I also ride. What kind of activity does a pedometer measure when bike riding? Does it matter if the bike is recumbent? Shouls I just take off the pedometer when bike riding? Do you have any pedometer recommendations. I was thinking about the Omron HJ-720ITC which comes with software to keep track of your progress.
