I have a giant reign E+1. I had some issues to. The rattle is the lost one who had to be solved. If I going downhill over some rough train my bike sound like a very cheap city bike. I hate it. Don’t know any solution
Owned a Giant reign e + 1 pro for 8 months. He is now back to the LBS for the second time. Lots of moisture problems. new motor and new electric cables and new controller. Everything new and a new battery next week. I am not at all happy with Giant's service. Front fork has also been replaced...
