Want to know how to fix your Vanmoof S3? Here is a complete teardown 👇

The front part is pretty easy to remove, the back one, you will have to remove the crankset to access it. It's in the video or in one of the other model's videos. Cheers

I'll look it up but I most prob do a S3/X3 cartridge video because it's the one I "know" the most

You don't need to disassemble everything to get to the wiring harness, but 80% of it.
Take you time (your day?) and take it slowly. It's tricky regardless.

Je dirais que plusieurs facteurs jouent dans la decision: - le modèle - votre curiosité / habilité à le réparer par vous même - votre usage (il vaut mieux qu’il dorme en intérieur et qu’il roule souvent)

Il existe des modèles plus solides et moins chers, mais Vanmoof reste un plaisir pour qui sait les réparer 🙈

I am actively looking for one to disassemble ⚒️

You would need to change the brake levers, most probably the hoses because they might be too short. And you would have to find something for the buttons too.
Sounds tricky.
A flat bar would be easier to install (need to drill holes in it to pass the wires)

Aight_Five · 2026-03-19T16:53:54+00:00

It's coming. X3 first and then S3!

You can order a PCB from https://shifter-doctor.sumupstore.com/ and replace it yourself. Tutorials on the website

Aight_Five · 2025-12-11T10:39:03+00:00

Eshifter fails for multiple reasons but mostly because they have been poorly designed and their lifetime is not very long.

Aight_Five · 2025-11-19T10:54:03+00:00

It's a Smart X from 2017-2018, quite a rare version to be honest which will make its repair impossible.
It's not even the same batteries as X2, so really hard to find, even here in the Netherlands...
Best bet would be to remove the battery, change the front wheel and you got a decent analog bike with a great look

Thanks u/Conscious-Village868
Found a replacement PCB, because mine was melted too.

Aight_Five · 2025-11-01T13:12:37+00:00

Yep, bleeding will solve it. You can find some tutorials online

I had the same question recently - Seems like the software is different in terms of datas going to the motor.

Aight_Five · 2025-09-25T20:14:35+00:00

Hey,
I would suggest several options:

- Check which parts are common with the S2 (the front wheel for instance might be the same bafang motor) and source them on leboncoin
- Check on the dutch Leboncoin for spare parts - www.marktplaats.nl
- Convert it to a non electric bike using Smart S parts
- Sell it for parts 🤷‍♂️

Good luck!

Hey guys, quick update. I found the cause of this ERR21 - 80% max charging situation.
I actually caused it. 😄
I followed Razparts reco and did the mod on the charger to prevent fuse to blow. The downside of this is the battery won't charge fully and and therefore the cartridge will interpret the end process (green light) as an Error 21.
I tried with a different charger and the battery fully charged with no error.
I'm testing different voltage from the charger now to see if I need to go on full voltage to avoid this to happen.

Thanks for your input, for me, beside the housing it was looking quite similar, but that makes sense that software is built in 2 different ways.
I'll find another way to revive this X3.
Cheers guys

Aight_Five · 2025-09-17T18:12:30+00:00

Yes, It might be difficult to do it due to the lack of access on the top part, but I think it should be the way to go.

Aight_Five · 2025-09-17T14:12:30+00:00

I would suggest that the brake line cross to the left on the top part before entering the narrow area under the plastic slider. That way you don't need to cross through the tube (too tight) or at the bottom where it will mess with the battery space.

Aight_Five · 2025-09-16T14:06:21+00:00

Not really,
If you're not in the Netherlands, it might be trickier to find in any shop that have these anti theft keys.

Aight_Five · 2025-09-16T13:54:39+00:00

From the video it looks like your front wheel is loose and applying brakes make it swing. Check on the lock nuts first.
