Wyze band counts steps while bicycling

Wyze band is counting steps while bicycling. More than 5000 over a 20 mile ride. Not a very bumping road surface so not sure if vibration could cause it.
Steps are counted correctly with similar number as iOS iPhone steps counter when walking.

Mine sometimes has up to 40-70 steps when I sleep.

sleep walking? /s

Haha, I don’t think so. I think the sensor is just not that accurate, but for a $30 device it’s pretty good when I’m actually walking or running.
