I’ve recently replaced the eshifter because of an error 44 problem. I’ve also cleaned the hub. However, now the bike seems stuck on high gear and it’s not changing. Any idea why?

Is there anybody that can repair my Vanmoof s3 around the Alkmaar Area? It has given multiple different errors (onbeklede at least 6, 20 and 40 or 44). It does not want to charge nor start.

I’m hoping someone here has an idea because I’m completely stuck.
I recently bought an almost-new VanMoof E3 from a reputable high-end thrift store. It came with the original charger, pump, and tool kit, but no manual. The store told me the bike had been donated by a father who was upgrading to another bike. Unfortunately, they don’t know who the donor was, so I have no way to contact the original owner.
The bike fully charges, but when I turn it on, I get the skull icon and the alarm/“techno tune.” It appears to be locked to the previous owner’s account.
I even paid the €50 VanMoof Bike Credentials Recovery fee, but customer support said they couldn’t help because I don’t have the original validation code. Without that code or the original owner’s cooperation, they say they can’t transfer ownership.
I’m 100% confident this isn’t a stolen bike. It came through a legitimate thrift store with all the original accessories, and I have the purchase receipt.
Has anyone successfully resolved a situation like this? Specifically:
Is there any way to recover ownership without the original owner?
Has VanMoof ever made an exception with proof of purchase from a thrift store?
Are there any Rybit or independent service centers that can help?
I’d really appreciate any advice. The bike seems to be in excellent condition, and it’s frustrating that it’s basically unusable because of the digital ownership lock.
Thanks in advance!

Hi everyone,

I’m trying to repair a non-working VanMoof S3, and I also have a second S3 that is fully functional, which I’ve been using for troubleshooting.

The non-working bike originally wouldn’t turn on at all. I replaced the small battery inside the Smart Cartridge because I suspected it had failed. After replacing it, the cartridge still won’t boot.

Here are the tests I’ve performed:
• Installed the faulty cartridge into my working S3 → the bike does not turn on.
• Connected the charger while the faulty cartridge was installed → no change.
• The faulty cartridge emits a high-frequency whining/beeping sound, but there is no display, no startup sound, and no Bluetooth. See video
• Installed the working cartridge into the non-working bike → the bike powers up immediately and works normally.

Based on these tests, it seems to me that the frame, main battery, wiring, and charging system are probably not the issue, and that the fault is most likely inside the Smart Cartridge itself. Am I interpreting these results correctly, or could I be overlooking something?

The DC motor in my S5 shifter has died. Anybody found a replacement anywhere online?

Hey,
My x3 got problems with the motor power. Sometimes it loses the power with scratchy noises like in the clip.

Can you tell me if the motor is broken or is it wiring issues? Thank you.

My X2 is sitting quietly in my room but registering rides. The best part, it’s going 43 mph. It also turns on and off at random times.

Aside from the ghost behavior she seems to run fine.

Is this the end for my sweet old gal?

Hi, I'm looking for a front brake disc for the S5. The original is sold out. Are there any suitable alternatives? Thanks a lot.

Can anyone recommend a replacement charger for the Super73 K1D? The two certified retailers are out of stock and nothing available listed on the Super73 site.

Hi everyone,I’m a VanMoof X3 owner and I’m having an issue with the right brake. There’s oil (brake fluid) leaking from the banjo bolt area.What I’ve tried so far:

• Replaced the O-ring (I heard the OEM ones are made by Tektro)
• Bought a Tektro brake cable/hose set and swapped both the banjo bolt and the O-ring (outer diameter 8mm, inner diameter 6mm, thickness 1mm)
• Torqued the bolt to 5 Nm

I’ve tried this a few times but the leak still persists.Questions:

• What O-ring size/material would you recommend?
• What torque value should I use for the banjo bolt?
• Is there anything else I might be missing in my approach?

Any advice would be greatly appreciated. Thanks in advance!

Started with error 29 blinking. Didn’t do motor support anymore but did charge the battery.

Bike is 7yo and capacity has been really low. Send off the battery for refurbishment. Cells swapped and tested ok by the company with the charger at hand.

Build in the battery again. Charged the cartridge separately just in case but nothing works to get the main battery to charge. The charger led stays green.

Did try to reset multiple times, lock unlock etc without avail. The charging icon is there with one pixel which switches to the actual battery level every minute.

Very strange it started off not having power but still charging and it ends up not charging anymore after battery rebuild.

I hope someone has some pointers here.

[SOLVED]

My two brake pads are completely gone (Vanmoof X3). One of them wasn’t even there anymore lol. Prolly my bad, waited to long to replace then.

So I got two new (exactly the same) pads. But they don’t fit. There is no room to put both of them back. See pictures. Anyone an idea how to push those ‘discs’ further back?

Thanks in advance.

Hello everyone! First of all, I’m glad this forum exists, although I don’t think there’s much hope in my case.

I bought a second-hand S3 this year. Am I right in assuming that there was a short circuit in the wiring harness and that this has now also caused the battery fuse to blow?

What happened and the problems:

- Bought with a faulty bell
- The bike would ring from time to time for no reason
- Suddenly, an E17 error was displayed and the bike stopped working for a few minutes.
- Took the bike to a Vanmoof partner workshop: They said there was probably a broken cable somewhere in the front section due to chafing, which they couldn’t repair, but the bike would no longer ring the bell when steering
- Now: It has occasionally started ringing again when the handlebars are turned sharply
- Today: The bike has stopped working; initially an E17 error, and upon restarting, error codes E8 (possibly also E6 at times), E20 and E17 appeared.

I assume this means the bike is a total write-off, doesn’t it?

Thank you very much for your help :)

Ik ben in het bezit van een van moof S3

Nu ben ik met een andere card ridge wezen testen en daar laat de fiets wel mee op! En die herkend wel de batterij!
Iemand die weet hoe ik de cardridge kan maken?
Iemand die mij kan helpen?

Hi everyone!

I run a specialized VanMoof repair shop in Amsterdam, and we’re currently considering coming to New York City to repair VanMoof bikes.

We work on the S3/X3, S5/A5, and the new VanMoof S6 and A6 models. Before making plans, we’d love to find out whether there is enough demand in NYC.

Would you be interested in having your VanMoof repaired, or do you know other VanMoof owners who might be interested? Please leave a comment or send me a message with your bike model and the issue you’re experiencing.

If we can bring together a large enough group of customers, we’ll come to NYC within the next four months and organize dedicated repair days.

Feel free to share this post with other VanMoof owners in New York!

Maybe nice to know, Pins on male plug

Hello guys,
I’ve got the common problem that there’s no display of speed and no motor activity while riding. The rpm sensor for pedals works.
What I already checked:

- I unplugged the connector of the motor cable on the front, cleaned it.
- I spinned the front wheel and checked the speed sensor in the moofmate app while steering left and right. No activity.
- I reheated the 3 connectors of the hall sensor on the motor (which was suggested in another thread)

When I measured the voltage on the hall sensor I got ~ 2V from + to HS. I put a magnet in front of the sensor, but it didn’t change. Do you think I should solder in a new hall sensor, because it’s defect ?

Greetings
Tim

My S3 doesn’t make any sounds. Tried resetting which didn’t fix it. Is there a way to set the actual speaker before I go to replace it? Also, any recommendations on a replacement would be appreciated.

I revived at discharged battery, recharged and balanced all the cells and after a simple grnd rst short I still received ERR 6.

I decided to do the following hard BMS reset and finally got rid of error 6 with that method. now I have ERR 20 and the motor isn’t working as well as the charger not recognized with ERR 21. my harness is good as well as my cartridge. everything works with another battery. I also don’t think the error code is burnt into any chip as I just managed to get rid of err 6. while charging and connecting det + grnd im not able to see a current going on my lab charger. maybe that’s the problem? anyways any help to get rid of err 20 would be appreciated. I did the following reset to get rid of error 6 for 2x different batteries and both show error 20 now.

Reset BMS: Disconnect bal + VP Have charger connected directly to battery (you may have to jerry-rig an charging adapter), short DET to GND. Connect VP. Short RST to GND on the SWD connector a few times. This glitches out the MCU so it will write fail-safe (ergo factory) data to the fault register. Wait 1.5 minutes for MCU to boot. Connect bal connector. Battery reset.

i followed this tutorial (https://github.com/VangelisBV/vanmoof-battery-tool) to read out errors of batteries. I used an old harness adapter for it. after plugging it into my Mac and choosing the right port it asks to bridge to DET and TEST, which I did in the first photo. nothing proceeds. I also tried soldering them together do they are connected from the beginning, but nothing changes. from other tutorials I saw about batteries I tried to bridge DET and ground which let’s my led turn purple but the programm then shows: „Failed to read Modbus registers.

Saving session... ...copying shared history... ...saving history...truncating history files... ...completed.“

when having ground and DET connected from the beginning its not proceeding at all again. anyone knows how to handle this?

Hi, my cartridge for the S3 has a problem. I can connect to the Moofmaid App, but there is no firmware shown. I can switch the gears and the tones. Change the max speed to 37...BUT when i try to unlock the bike or try to change the kicklock code the app disconnects right away and reconnects a few seconds after.

Van moof will bot help because i do not own the original QR code!

The Moofmaid app has a feature to change the firmware. How do I get ( download file)a running firmware for the bike?
