I just got my front tire changed and now I keep getting a low front tire pressure , low battery message, almost non stop. I checked the tire pressure this morning and it had gone down from 43 to 33 psi. filled it up again and lasted all day. Do I have a broken tire sensor for the front or is it really a battery issue. I also have had that issue since I had this bike that if she sits for a week , low battery but does charge fairly quickly. Ted Proud to be American!
