My Speedo just died after a full charge. When I turn it on and it initialises, the dial goes to around 10mph, flickers then drops. On rides it doesn’t go above 10mph no matter what speed I’m going.
Do you think it’s the controller too?

please go to your dealer, use your warranty.

Couple of times now my speedometer has just dead dropped but quickly picked back up

Having trouble there! Super soco told me not to bother with my local dealer then the next closest dealer told me they were too busy to deal with it!
