Manual: Replacing the Printed Circuit Board of a VanMoof E-Shifter
This manual describes the steps for replacing the printed circuit board on a VanMoof e-shifter. Follow these instructions carefully for a successful repair.
Supplies
- Allen key 2.5
- Flat screwdriver
- Dishwashing soap
- Hot water
- Degreaser (e.g. Loctite 7063)
- Towel
- Glue (for example Loctite SI 5910)
Step-by-step plan
1. Cleaning the E-Shifter
- Clean the e-shifter with a mixture of dish soap and warm water.
- If necessary, use a degreaser for a more thorough cleaning.
- Dry the e-shifter thoroughly with a towel.

2. Removing the Screws
- Remove the 4 screws with the 2.5 Allen key.
- Note that the two screws holding the metal bracket are shorter than the other two. Set them aside for now.

3. Opening the E-Shifter
- Turn the e-shifter over and use the flat screwdriver to open it.
- Once you've gotten started, turn the e-shifter back and open it further with your hands. This will keep the gears in place in the lower half.



4. Loosen bearings
- Sometimes one of the two bearings on the main gear gets stuck on the gear.
- Use the flat head screwdriver to carefully loosen the bearing by inserting the screwdriver around the bearing.


5. Disconnecting the connectors from the PCB
- Disconnect the connectors from the printed circuit board (PCB) by inserting the flat-head screwdriver between the plastic edge of the connector and gently prying the connector loose.

6. Preparing the Housing
- Remove the old adhesive residue. This can often be easily done by pulling it off. Use a flathead screwdriver for any remaining residue.
- It may help to use some degreaser (Loctite 7063) when removing adhesive residue.
- Also clean the main gear bearings with degreaser.



7. Replacing Parts
- Start by replacing the main gear bearings. Apply a thin bead of glue before replacing them.
- Then, place four drops of glue where the PCB will be mounted and press the PCB into place. Make sure it sits properly on the guide points.



8. Connecting the Connectors
- Reconnect the connectors. Note that some circuit boards have a design flaw that requires the 4-pin connector to be reversed.

9. Checking the Metal Ring
- Check that the metal ring in the plastic housing is still in the correct position. If removed incorrectly, it may be twisted; be careful.

10. Checking Gears
- Check that all gears are still in the correct position.
- Replace the main gear and turn it to the null position so that everything lines up correctly.


11. Checking the Main Gear
- Check that the main gear is flush with the other gears. If the main gear is higher, the gears may not be properly engaged.

12. Gluing the outer edge
- Now apply glue to the outer edge of the e-shifter and around the screw holes.


12. Merging the Two Halves
- Now reassemble the two halves of the e-shifter. Hold the half with the gears at a slight angle and move the half with the electronics towards you.
- Make sure all parts stay in place and be careful not to pinch the wires in the housing.

13. Replacing the Screws
- After reassembling the e-shifter, replace the screws. Make sure the two short screws are placed back into the metal bracket and that the cable and bracket are properly positioned.



14. Mounting on the Bicycle
- Now follow the installation instructions to put the e-shifter back on the bike.
15. Error 44 Treat
- If Error 44 does not disappear immediately, reset the bike and plug in the e-shifter while switching on the bike.
Congratulations! You've successfully replaced the VanMoof e-shifter circuit board and reinstalled the e-shifter. Double-check that everything is working properly before riding again.
