CCC Mods Rent-a-Bike To Allow Free Rides

Autoversicherung writes "Germany has an activated by phone bike rental system across all major cities. At 6 cent a minute quite pricey, germanys famous Chaos Computer Club thought a free ride every now and then couldnt hurt. Optimizing the original system in the process, modifying the blink code to be easier found and changing the logo. About 10% of Berlins bikes are patched already. A detailed description of how they did it, and how the system works."

Perhaps some philosopher could conclude that I've really just abandoned the bikes, and rather than hacking 10% of them, CCC might have done better to hack 100%.

Hippies scrounged up old bikes and parts during a transit strike, got them working and painted them white, and then just left them all over the place for people to use for free. Sort of a bicycle version of the GNU project. If you needed to get somewhere, you'd just find a white bike, ride it wherever you were going, and leave it for someone else to find and use.

    This was several decades ago. Witte Fietsen actually worked as envisioned by the hippies, and was successful enough that local government decided to pick up the expenses. It is still active today in some parts of Holland, though in the big cities, sadly, the bikes get stolen too fast.

They did take a bike out of service for a few months, but they appear to have put all of the bikes back, and taken care not to disturb the system. Other than to enable a very small group of people to get occasional free rides on a small percentage of the bikes.

      Not to say that I'd encourage this sort of thing, but it really falls more into the category of a mostly-harmless prank, rather than real vandalism. It's entirely possible that Die Bahn even makes money off of it, since free riders who can't find a hack-a-bike will probably end up taking a call-a-bike quite frequently. If they didn't get the free rides they might have chosen to just ride their own bike. And Die Bahn certainly got some free penetration testing.
