    I'm having some issues with my BBSHD that just started this morning on my commute in to work. The drive maybe has 150mi on it tops, and has worked flawlessly until this morning. I decided to pedal the bike in the flats this morning on PAS level 1, and everything seemed to be going fine, but when I stopped at a light, I noticed that the cranks no longer freely run backwards; they're sticky -- not frozen, but not what they were literally 10 minutes earlier. I wasn't pedaling particularly hard, and didn't hear any mechanically disturbing noises, either before or after. Anyone know what might be happening?

    HI Lost Boy,

    If you send it back to us we will do surgery on it for you.

    Alternatively we can send you the bearings we think will fix this and you can put them in yourself.

    At the same time we will post a video and instructions on how to do this.


    It is not that hard of a job and this way the bbshd can stay on your bike. Also you got the added security of knowing if you screw up the repair you can always send it back to us at that point ad we will fix it.

    Thanks Louis! You guys have been really great. I have never had such quick responses to support questions and I feel confident if there is further problems I don't need to worry. I'm just throwing in my 2 cents into the trouble shooting forum.

    As far as the gear noise goes it's the same. Loud but not outrageous. It's pretty much the same as before I packed it with grease. I'd like it quieter but it works amazing. Should I worry about the gasket? It's a bit torn after contact with the grease.

    Thanks again guys! Great product. Amazing support.

    As I promised, we will stand behind it and replace. Maybe it's time for surgery! When you remove the drive side cover the axle is basically floating and will lift out with no resistance. That is normal.

    I have 2 BBSHD bikes. The first one has been flawless. The second has had a couple problems. The first issue was the play in the axle. As Eric said just a couple of mm. Did not seem to affect performance. It hasn't worsened over time. The second problem is noise. It started off silent then developed noticeable gear noise. I discussed this with support and they suggested opening it up and packing with grease. This seemed to help a bit for a time. So I repacked it again. No real help. Like I said motor still performs like a champ but not silent any more. There is the constant noise of the gears. Also when I removed the drive side cover instead of a couple mm's of play in the axle there is almost a cm. This is resolved again when the cover is reinstalled. I think I'm just waiting for it to die. I don't think I can pack any more grease in there. Also the gasket between the housing and motor is essentially paper and is destroyed by grease...

    Pedals "Break" loose


    This was the first BBSHD failure we saw and it has happened on 2 drives so far.

    Symptoms:
    This usually happens with hard pedaling the customer feels a breaking and then suddenly the customer can no longer pedal the BBSHD although the power function still works fine. The pedals just spin loosely without contributing any power.

    Culprit
    This is the clutch breaking.


    Solution
    Luna Cycles now stocks the clutch and the part is easily replaced without the drive coming off the bike. Estimated time for repair is less than 30 minutes.

    PLAY IN THE AXLE

    We have had 2 BBSHD come back with play in the axle. You can really see this with the pedals on. The axle would slide back and forth a few millimeters.

    We noticed that one of these BBSHD had been taken apart by the customer and it looks like maybe not put together right which caused the problem.

    Culprit:
    This is a problem of the race bearing which can become disassembled which causes the play.

    Solution
    Luna Cycle is now stocking this 3 piece race bearing and the part is easily replaced without the drive coming off the bike. Estimated time for repair is less than 30 minutes.

    Bbshd failures and troubleshooting

    I thought i would start a thread that would document the few BBSHD failures we have seen and what the issue has been Overall i am super impressed with the very low failure ratio of this new drive. The BBSHD is built like a tank.
Working...
