No idea where it is from, spotted in Switzerland

I often see people here mentioning the problem of poor traction, which I also experienced. My first attempt was to use 3D-printed wheels, but they wore out very quickly because quite a bit of force is exerted on the tires (when turning). Then I saw somewhere that someone had solved the problem for me using spikes from car tires, so I tried that too. After over a year of use, I can highly recommend this affordable solution. Virtually no wear, even on gravel paths and garden pavers. Charging still works without any optimizations.
