Cause you can ride no handed. Empty
your pockets b4 you ride. Unless you have deep pockets. I stopped a mile into our ride to adjust the air cushion and my small flashlight fell out of my swimming trunk pocket. Wait, my phone was in my pocket. Not now. We doubled back 1/2 mile and found it on the path. Never heard it impact. It has a hard case and a rubber boot around the perimeter. Prob landed on its edge.
So learn from me. Could have ended
