Hello
I bought a Bergamont e-revox 26 jr for my son. Every 3 or 4 bike trip the chain jumps off the front gear and gets stuck between the frame and gear. This happens when he travels straight forward on nice flat roads. This is a BIG problem. He is only 11 years old and gets stranded all over the place. The shop where I bought the bike does not find anything wrong the bike. What now??? Is there a chain stabilizer that fits the bike and will help? Or anything else?
