I have a Ride1Up Step through bike and the chain falls off the front chain ring especially when I hit slight bumps. Has anyone else had this issue? I brought the bike to my local bike shop after Ride1Up support told me to remove a couple chain links. The bike shop looked over the bike and discovered that the chain line is off. They told me the chain was at the correct length and they wouldnt recommend taking links out. The told me the chain length is so far off that there isnt anything they can do and it appears to be an issue with the design. I am very upset since I spent a good amount of money on this bike. Has anyone else had this issue?
