Introduction

If your bike isn't charging, this guide might help you fix it.

  1. qtmM36CSkfDPdUmP
    • Under normal conditions, when plugged in and not fully charged, the light on the charger should turn red. If it stays green (as shown) even while the bike itself indicates charging, the solution im going to lay out will probably work for you.

    • Vanmoof has a great video on how to remove the smart cartridge. You will need to buy the necessary Torx wrench because I don't think it comes with the bike.

  2. n3LjxyHIXBuJMIjK
    • Remove all the screws from the circled plate

    • Pull apart that half of the smart cartridge. There is adhesive near the charging port so it may be a bit tough to pull apart at that end.

  3. FfZeSdaffWbUBVCo
    • The pictured connector should look burnt in some way. Ive seen a few that get completely melted

    • Cut the plastic off the wires and then strip them so that they can be soldered to the pins

  4. xNNnVHYGfcjHc5Nw
    • solder the wires to the pins where the connector used to go

    • reassemble everything and the bike should now charge

Thank you. I'm not very skilled with such things, but it worked out pretty good and I didn't find it to complicated.

sure np I didn't think it was "difficult" either but the description of difficult said something like "requires soldering" so I put it as difficult 🤷‍♂️

Coleman Oei -

Fiddly but not complex. I was using a soldering iron for the first time and just about managed it. Thanks for the post.

Hi, I have same problem, I think there is a problem with the bms ! Any idea how can I fix it ?

Kreont i -

sorry. dont know much besides what I wrote above. If you have more details I might be able to help. There is also a vanmoof subreddit that has been able to instruct me on how to fix a lot of the issues ive had with the bike so you might try that.

Coleman Oei -

is there a guide for the X2, same issue.

David N -

Did you manage to fix it ?

Kreont i -

I'd think the s2 is similar and might be exactly the same. I think it would be worth it to take the cartridge out and open it up to see.

Hi, I have same problem, I think there is a problem with the Darfon BMS!

I swap the battery with another one and works fine.

Any idea how can I fix the bms ?
