I really hate bicycle repair work. My son's bike was broken. One of the pedals had broken of.
And that seems a simple fix. Screw out the remaining axle nub and screw in a replacement.
But it was stuck. I used penetration oil. And heat. Couldn't get it lose.
Oh, well. I have another VanMoof for parts. I'll replace the complete crank and front cog.
Couldn't get it lose. Again. Bought a crank puller. Still no dice.
Fuck it. I have long covid. This is costing me to much energy. I'll take it to a bicycle repair shop.
There is one in walking distance.
They are to busy, please make an appointment on the website.
I can't figure where on the website.
Just write a mail.
No reaction.
I am calling them and when it says press 2 to make an appointment.
I press 2.
The connection gets cut.
Fuck it. I just drill out the axle. It's a pain. But I did it before, well sort of
Two days later I have a hole where the axle used to be. But the aluminium aloy has completely melted into the groove of the crank. No way I am getting that to an usable state.
Fuck it. Admitting defeat I combine the wheels, tires and mudgards with the other frame.
I hate VanMoof.
Know to find someone that can replace those cranks on the frame. So I can have two whole bikes again

Gestern Gespräch mit einem Freund über #vanmoof, #eautos , #SecondSight (https://www.chip.de/news/Augenimplantate-funktionieren-nicht-mehr-Pleite-des-Herstellers_184110188.html) geführt. Er: „Für Pleiten/ Ende des Supports müsste der Code öffentlich zugänglich und nutzbar werden.“ 😉 Jep. Plötzlich sorgten die Begriffe #linux #opensource und #signal nicht mehr für Schnappatmung
My latest blog post: I'm presenting at the 2025 Open Hardware Summit
https://mikecoats.com/presenting-at-ohs-2025-cta/
I'm excited to announce that in one month's time I'm presenting at @oshwassociation's Open Hardware Summit 2025. My talk's titled "VanSpoof and F**dG3ar: Reverse engineering proprietary bike components to prevent e-waste" and covers everything involved in designing replacement, open source, parts to repair VanMoof e-bikes.

My latest blog post: Selling Products on Tindie

I'm now selling my electronics kits on Tindie! I've listed my Spy! Break! Inject! and VanSpoof projects as assembled products, kits and bare PCBs.

W00t! Got my #vanMoof #MCP server working in #n8n. Here an example of me asking what my fastest rides was last week.
My latest blog post: VanSpoof v1.0
https://mikecoats.com/van-spoof-v1-0/
I'm happy to announce the v1.0 release of VanSpoof. My VanMoof X3 now starts up, without an e-shifter connected, and does not show an Error 44 status! The bike thinks it's connected to a working, functional, e-shifter!

@luebbermann finde diese integrieren Lichter auch problematisch.
Vielleicht schick, aber propreitär: kein Standard sondern Hersteller spezifisch. Gut Licht kann man immernoch durch ein einfaches Licht ersetzen, aber gilt das auch für alle anderen Teile oder macht man sich da Hersteller abhängig?
Bin seit meinem #vanMoof da ein gebranntes Kind.
Based on my vanMoof REST API reverse-engineering efforts I've created a (Model Context Protocol) #MVP server for #vanMoof.
Anyone interested?
I hope to find some time soon for a public release soon...
Here already the link to the api info.

My latest blog post: VanSpoof - Prototype 2 - Shrunken PCBs
https://mikecoats.com/van-spoof-prototype-2-hardware/
The VanSpoof PCB has to be no bigger than 31.5 mm by 21.5 mm to fit. Unfortunately, Molex's SMD footprints are quite wide so the board needed a fair bit of layout work to make everything fit.

Sitze nun hier in der Sonne an der Weser und beobachte Radler.
Spätestens jedes Dritte Rad hat eine laute Kette..
das #vanmoof Duo kämpfte sich den Deich hoch.
Habe nun interessante Räder und Helme gesehen.
Könnt‘ hier den ganzen Tag sitzen.
My latest blog post: Low Tech Prototyping
https://mikecoats.com/low-tech-prototyping/
My existing prototypes are too big to fit on the bike, so I turn to one of my favourite low tech prototyping methods; 1:1 scale models in card and fibreboard!
My latest blog post: VanSpoof – A-Muntzing We Will Go
https://mikecoats.com/van-spoof-muntzing/
With my first few VanSpoof prototypes assembled, I had noticed that the L78L05 was sometimes getting a little hot. Instead of knuckling down and calculating more suitable component values, I turned to the tried and tested method of Muntzing to get my power draw down.

Ich hab grad nen A5 Gepäckträger bei #VanMoof bestellt, das letzte Mal als ich das gemacht habe sind sie kurz darauf insolvent gegangen. Schaunmermal….
My latest blog post: VanSpoof - Prototype 2 - Echo Firmware
https://mikecoats.com/van-spoof-prototype-2-firmware-1/
In part 1 and part 2 of building my first VanSpoof prototype, I managed to flash the microcontroller on the PCB with a blinky demo. This time round, let's see about sending and receiving some serial data.

Last time, we built a prototype PCB. This time, let’s take it to blinky!

My latest blog post: VanSpoof - Prototype 1 - Hardware
https://mikecoats.com/van-spoof-prototype-1-part-1/
Let's look at building a prototype PCB for my VanSpoof project. I really want to get better at soldering SMD components, so I'm going to try to use as few through-hole parts as I can get away with.

https://mikecoats.com/vanmoof-eshifter-reverse-engineering-part-2/
Now we've tapped in to the wiring of a VanMoof e-shifter, let's work out the baud rate and format of the data being transmitted and which format of messages are being exchanged between it and the bike.
