Any #BikeTooter folks with #Tongsheng #TSDZ2 “Error 30” troubleshooting skills? I’ve been fighting with this for a few weeks. I get the error on three different displays, with two different display cables, and two speed sensors. The motor cuts out after about 30 seconds and the display turns off. All my searches on the many forums point to a failed controller. Is it time to buy another motor? #ebike #Error30
