Step Tracking Anomaly

RoCla

Does anyone who uses a fitbit or other tracker ride a motorcycle? My polar loop has always had a quirk when counting steps if I am riding my motorcycle. I think it has to be the vibration tricking it. After riding for a couple of hours today, my tracker now says I have walked 16,504 steps. I was just wondering if this is a problem with other trackers as well. I have just learned to check my steps before ride and subtracting the that from the after ride total for actual to know how many over it is tacking.
Thanks, Rosanna
