Hi, I have a bbso2 mid drive on a yuba cargo bike. It was recently serviced (regreased and packed) and was working ok for a couple of rides, then suddenly the motor wouldn't cut out when I stopped pedaling and would just keep charging onwards. I can shut the motor off by turning pas down to 0 but once I touch the throttle or pedal, the motor kicks in and doesn't stop. I don't have the brake sensor/cut off on my bike (out of stock when I bought my kit and I seemed fine without it for the past couple of years).
I checked all my cables and connectors, they seem fine, I unplugged my throttle and problem was the same. Hoping someone might recognize this problem, I saw one thread where a similar issue seemed to be a broken pas magnet, but I've looked into that before and it seems that if you had a broken magnet, the pas wouldn't be working at all whereas mine does kick in when I pedal and the throttle activates the motor just fine as well. It just doesn't stop when I stop pedaling! I don't have the tools or a great space to take on a project like opening up the motor but I'm thinking I might have to start figuring it out with this glitchy system![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
