So, After a brief 9 mile ride, my 2 day old Rad Rover 6+ decided to have an error 21 code on the display. I went through the on-line support and did all the checks suggested on the site, but had no luck in restoring the bike into a workable state.

I did contact support subsequently and they ordered a new controller for my Bike under warranty, which is expected and the service was really prompt.

So now waiting for the controller (it has not been shipped as we speak) i was hoping some folks may have insights on what will cause the error and if there is a fix which does not involve replacing the controller, i.e. can it be reset in some way to clear the error or is the controller a throw away part. Obviously having had the bike for 2 days and only had one ride on it i am quite disappointed. I truly hope this is a once-off occurrence.


Any insights would be appreciated...
