    BBSHD Troubleshooting Random issues on unit still moving

    Pedals spin but do not move bike. Throttle still works perfectly fine. Blown clutch. Clutch needs to be replaced (easy repair).

    BBSHD is louder than when it was new. Consider taking apart and adding a high quality Mobile 28 grease.


    See this video to hear a comparison of how much difference some fresh grease can make


    Getting an error code but the bike is running normally. (read this article on error codes and what they mean)

    Display wont turn on but bike still runs. Your display has gone dead and needs replaced. You can use some the testing here to help you out.

    BBSHD is making funny clunking noise. It is time to take it apart and see what is going on inside.Luna greasing guide here

    BBSHD Is making an awful grinding noise. You have probably fried your nylon gear. This is rare occurrence on BBSHD but will happen if you run it too hot and in the wrong gear. Use the greasing guide to replace the nylon gear. Luna greasing guide here

    PAS not working properly. Try reprogramming (see this resource) which usually fixes this. Otherwise a new controller is probably the issue.

    Chain falling off often. Chain alignement issue. Consider going with an aftermarket chain ring such as the Eclipse or Lekkie which will give you more offset and better
    chain line.

    BBSHD sprocket rubbing against the frame. Installation issue. Read this article on getting the bbshd to fit. Or try a smaller chain ring, or use spacers somewhere.

    Chain skipping. Skipping can be due to a lot of things that happen during regular use. An old chain, a chain with a link that is not bending properly, a bent derailer, a derailer that has not been tuned/indexed, a bent/missing tooth on the chainring, or perhaps (although less likely) something in the motor itself. Anything besides the motor can be handled by any local bike shop and is more or less just part of owning a bicycle.

    BBSHD runs fine when I lift the back wheel but when I ride the bike, I get power cuts all the time it feels like someone is switching the power on/off/on/off... OR I rode the bike and the power cut but the LCD is still on!

    If you just experience power cuts and the LCD/motor stay "ON" :

    Look at your brake sensor, if the magnet is too far apart a slight vibration can trigger the sensor and cut the power to the motor, to test, unplug the brake sensor and go for a ride!
    A brake sensor can go bad and be stuck in the "brake" position, unplug the brakes sensor and test the bike.
    Also a bad gear sensor could also do the same, so unplug it.

    Can also be a pinched gear sensor cable, look out for a crushed cable.

    If it is running but you have error 30, you may have pinched wiring harness, see below pictures for an example. Typically you do not want to put your main wiring harness in this location because if the motor hits downtube it'll crush the wire:

      Lower power output during winter:
      All lithium batteries have greater voltage sag if subjected to very cold temps.
      If storing your bike in the cold weather during winter you are going to have less power output because the voltage sag.
      If using in snow maybe insulate the pack, and try to store pack indoors.

        Motor rotating after Installation

        T
        here can be a couple of reasons why this can happen
        1. The Bottom bracket shell is a couple of mm smaller than the BBSHD BB, Fix: add spacers between the triangle plate and motor so there is plenty of thread to tighten the motor to the correct torque.
        2. There wasn't enough torque applied at the time of installation. Fix: Re-torque motor to remove movement.
        3. The motor maybe hitting the chain-stay on the drive side. Fix: Remove and add shims so the motor clears the chain-stay.
        4. Teeth not seated - May need to retighten the lockrings after first ride and next few while the parts are "settling" in

          Power cuts on and off during a ride. Sometimes a press on the power switch will bring power back but only for a minute . Sometimes power goes on and off without input.
          Where should I start my search father culprit? All connections have been examined and seem fine. Bike has performed without a flaw for 9 months. Now this. Suggestions?

            An intermittent problem which occurs at all speed/power levels could be a loose connection or short in throttle, brake cables, gearsensor cable or connectors between controller>motor. A problem that only happens at high load is more likely to be something getting hot. Which could be a high resistance connection or short in the power wiring, or an overheating controller, or an overheating battery.

            If it is a hardcase battery, also be sure to check the contacts between case and cradle.

              Just started yesterday, when using the throttle in PAS 0. The pedals spin with power as in you can't stop them. Let off the throttle and then they can be easily stopped Same issue with PAS. You cannot stop the pedal from pedaling without slowing to a stop or cutting to PAS 0. Usually the bike will freewheel when you pedal in reverse. There is resistance now. I changed the clutch and it is still doing the same thing. clutch was brand new. I did put a little tri flow on the pawls prior to installing and greased the primary again. i will open up again tomorrow.

                Figured it out. One washer too many on the crank set.
