Hi everyone, a pleasure to join this group! Maybe you guys can help with an issue I'm having. Thanks in advance!
I installed a BBS02 on a mountain bike a couple days ago and was thrilled with the results. Everything was working correctly. Then, the throttle stopped working and the pedal assist stopped working at the same time. It's a 48V battery, the controller is set for 48V, the display (750C) is displaying 51V (as does the advanced charger), the brake (only one hooked up) seems to be working fine since the display shows when it is depressed, no gear shift sensor is installed, the connection to the battery seems to be fine. Everything looks to be fine, visually and on the display. However, no power goes to the chainring, and the display no longer will show power going to the bike, as is obvious from riding it. It does have one thing that might be a clue. Sometimes when the throttle is turned, the chainring turns about a quarter of an inch at its circumference before stopping. Barely noticeable, but it does happen.
I was ridding it fairly lightly when it happened. No more than 500 watts for short intervals on level ground. The motor was slightly warm, but it didn't seem unusual.
Anybody have a clue what the problem may be?
Thanks so much!
