I’ve seen a few posts on here from people saying they get “motor error” from time to time and like me turning the bike off and on again resolves it. Well it didn’t when it happened again the other day. And much more alarmingly the bike took off entirely on its own with me running alongside it trying to stop it! Very dangerous. The dealer had a look and discovered that the battery was running an old software version and the motor a new one which may have been clashing with each other. Only time will tell if it’s worked but if it happens to you, get them to check all your software versions.
