I put a 1000 bafang mid motor on a micargi Seattle I can’t seem to get the motor to stop moving like the lock ring on the bottom bracket isn’t strong enough for now I just put on a gear clamp and a couple of tye wraps any ideas
Ya thanks I used a ball pien hammer and a snub nose chisel and pounded it pretty hard didn’t want to break anything I’ll try again but if not I’ll weld on a motor stopper/holder gizmo to keep it from rotatingThat ring...there are 2.
The first one really tighten it down...then get a brass mallet or rubber hammer and REALLY torque it down.
Then that second lock ring...use blue locktite and torque'er down but not as hard ad the forst ring.
On my BBSHD builds it takes alot of tightening that first ring.
Hope this helps!
The locking ring on the bottom bracket is not quite sufficient for a motors with so much torque but it’s a work in progress I supposesome moar better pictures of the other side please so we can see what ya did with the band clamp?
I also use 2 of those worm screw band clamps ..one around the frame and one around the motor and through the one on the frame to lock it all in and you should get no movement.
So you're on the right track right there brother.The locking ring on the bottom bracket is not quite sufficient for a motors with so much torque but it’s a work in progress I suppose
