Introduction

This is the second time one of the buttons stopped working correctly, caused by wetness.

The first time it was the boost button, following with an error 41, I took a trip to Amsterdam to get it fixed fast. They shipped my bike back a week later.

This time it hit the bell button, it got wet and stuck. 

First I tried to fix it with compressed air and ethanol. It worked for a while, but then it started to double tap every time it got pushed.

So I could not unlock the bike without a phone.

This time I wanted to try to fix it myself.

I called for support, and they sent me a replacement cable, telling that it will be an easy task.

But they have not sent a manual, and I could not find any tutorials online. So I just tried it myself.

Here is the result.

I hope this helps!

  1. You will need this tools: Hex wrench 2mm (not included in VanMoof toolbox) Hex wrench 4mm (included in toolbox)
  2. In my case the button was glued additionally. Cut around it to make it loose. Use the 2mm hex screwdriver and remove the tiny screw on the side of the bell housing. Use the pliers to unscrew the button.  Screw to the left.

    • Don't you cant break what is already broken. It should come of easy, so keep cool. Although - in my case the button top broke off.

    • Don't forget to turn of the bike!

  3. The 5mm screw is located below the button. You need to loose it. (Loose but do not loose.) If you unscrew both. You can try to blow compressed air through the holes. This can already solve the problem.

    • This screw holds the break/button part on the wheel. Later you will need to pull it off. As you can see the cable goes through the rubber grips.

  4. Use the wrench and the cloth to remove the handle grips. The cable goes through it - than through the handlebar. At his point you could just solder a new button to the old cable and be done. If you don't want to wait for replacement party from VanMoof - this buttons on Amazon have the exact dimensions and are waterproof,

  8. If you are unlucky and loose the cable inside. Try to fix it to a wire. You can also try to use the wire, to block the path through that hole in the wheel, and push just the cable. It should than bend and appear in the hole. Use the hole and the tweezers to get the cable halfway through.

  9. Put everything back together. Use some proper electrical tape to get the cable in place. Before you put the tiny 2mm hex screw should, check if hits the flat part of the side of the button. I removed the old glue with the tweezers and  applied some fresh hot glue.
