I have a new Aventon 500.2 pace and as I have posted before it keeps showing error code 22 throttle error. I have to say Aventon are great to work with and will not hesitate to send parts to try to fix the problem. They sent a new throttle and same problem. So they think the controller is bad. I haven't received the controller yet but today I unplugged the throttle and the bike worked great. Do you guys think it's worth changing the controller?
