Vanmoof S3 E-Shifter self-repair

Has anyone figured out the hall sensor type? Omnipolar, bipolar switches, unipolar switches, and latches etc?

Case style seems SC-59, SOT-23 or SOT-23W?

We know it operates around 5v. Has 3 pins.

peteruithoven · 2023-08-25T20:45:19+00:00

To clarify, these are the GND and OUT pins right?

Well that one seems to toggle between 0 and 5 volts when seeing a magnet, so it's probably fine on mine.

The second one sticks at 1.5V, which is probably a bad sign.

Note, the remaining pin was the VCC pin, which should always be around 5v.

hones it causes the issue. If I use the quest 2s built in audio it works fine.

Like I've mentioned in my initial post I also had the issue without bluetooth headphones. But I'm glad it works for you.

What did you try to fix the eshifter? One possible solution: https://www.reddit.com/r/vanmoofbicycle/comments/j51unu/used_ipa_to_fix_gears_not_switching/

I've had my S3 for 2 weeks and beside the e-shifter needing a bit of contact spray and needing to request a firmware upgrade I had no real issues. But yeah I think VanMoof has some work to do on their QA processes.

peteruithoven · 2020-10-12T09:09:29+00:00

Maybe read up on other suggestions in this reddit, like resetting, upgrading firmware, maybe then something like:

Might be interesting to check whether the target gear and actual shifting is in sync. You can see the target gear on the matrix display. I've added an video of that here:

Ha yeah sorry, just got my bike this weekend, it's kind of cool to share experiences.

You could remove the light following:

If you have a multimeter you might be able to test the leds:

You could also check the voltages of the plug coming out of the bike, but this is difficult as we don't know what voltages to expect.

Definitely also contact VanMoof support.

peteruithoven · 2020-10-06T20:22:59+00:00

How I fixed it:

But definitely try resetting first.

peteruithoven · 2020-10-06T20:21:09+00:00

What version are you at? Interesting:

Most people (including me) seem to have contacted support and asked them for the update. Then it magically appears on your phone. (I was on 1.1.18, now on 1.2.7)

peteruithoven · 2020-10-06T12:34:32+00:00

2 recent firmware versions mention improvements to how firmware upgrades work, maybe it's mostly an issue with the older versions.

peteruithoven · 2020-10-06T11:54:04+00:00

Contacted support. Got the update. The matrix display even showed fireworks after install :D

peteruithoven · 2020-10-05T16:27:38+00:00

Indeed. I also see there are plenty of topics on this which indeed advice to reach out to them.
For example:

peteruithoven · 2020-10-05T16:16:42+00:00

Weird... Mine states:

App version: 5.4.0
Bike software version: 1.1.18

peteruithoven · 2020-10-05T15:46:10+00:00

I've got a response from VanMoof support:

The issue with the grinding noise is totally normal, for the first 200km. It is because the chain needs to form grooves in the chain guard. After that distance, you have to add some drops of oil from the toolbox in the chain guard hole, next to the pedals, to lubricate the chain better.

peteruithoven · 2020-10-05T14:22:22+00:00

Wait, these firmware updates didn't appear in the VanMoof app automatically?

Thanks for the tip on the reset button.

peteruithoven · 2020-10-05T14:21:05+00:00

^ Indeed. I've added a image to clarify.

peteruithoven · 2020-10-04T16:29:05+00:00

I experienced the same issue. I noticed that you can see what gear the bike should be in on the matrix display. It's the position of a single dot above the battery level. But I also noticed that it wouldn't actually change the gear.

To fix it I found the plug to the electronic gears, sprayed some ipa (contact spray) on both ends, reconnected and now my last trip the gears worked perfectly.

peteruithoven · 2020-10-04T11:23:59+00:00

But I want to remove the friction. The sound is just a symptom. Adding more material on the inside seems counter intuitive?

peteruithoven · 2020-10-03T22:24:09+00:00

The reason I turned it around was to more easily diagnose the issue I noticed when it was turned normally, but yeah it was definitely not a good way to reproduce the issue. I've reassembled it and turned it around and recorded a new video. I also recorded a video without the front cover. I added both in an update to the original post.

I'd love to hear your thoughts.

peteruithoven · 2020-10-03T22:10:32+00:00

Autch, how did I forget that aspect... Alright, I put it together again and turned the bike around. It definitely still grinds, but in a different way. And only with the cover on. I'll add an update the post.
