      someone tries to convert the streets of a city into their private retail space without paying anything for it?

      If I run a bike shop and pay rent and/or taxes on the property, so anyone can come look at the bikes but if they want to use one, they have to pay, that's a normal retail situation. I'm entitled to control what happens with my bikes within my private space.

      What happens, though, if I just start locking the bikes up to lampposts and advertising that anyone can call a phone number to pay to unlock them? Am I not trying to convert the public lampposts into private retail space without paying any rent or tax? Who is taking what from whom? 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%.

      BTW, the public bicycle concept AFAIK started in Holland, with the Witte Fietsen ("white bicycles" in Dutch) project. 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.

      The dial-a-bike thing seems like a pale imitation. Witte Fietsen didn't need to be hacked.

      • The "someone" in this case is the city or some such municipal body, so they own the streets, so what they do with them is their business, so all your talk of "private retail space without paying anything for it" is just a complete red herring.

        Regardless of that, a weak lock isn't an excuse to commit what's clearly a crime, taking something that's not yours to take without paying the proper price for it. A weak front door lock doesn't give you the right to enter someone's house, watch their TV and take a na

        Ah, so without having to think about whether you're stealing from a fellow citizen, you blame it on an unspecified, undefined "philosophy". Ridiculous.

        You can't compare the taking you're doing with the Dutch bicycles, because those were intended to be free - here, you're just committing robbery from your neighbor. Everybody leaves bikes locked to public property, everywhere. You just aren't willing to admit that you like being a thief, and only because your victim doesn't get to see or catch you. Because if you did, you'd start stealing from little old ladies, and you'd probably like it too. You have no shame.

        Saying that bikes locked to public property are abandoned is absurd - when you park a car on a public street, and lock the doors, you must be abondoning that fine set of wheels [www.inet.hr], I guess, right? Let me know where you live, and I will come rid the street of your trash!

        For the record, Witte Fietsen didn't work because nobody wanted to take responsibility for fixing or replacing broken parts, plus people like you stole the bicycles and painted them other colors.
        • when you park a car on a public street, and lock the doors, you must be abondoning that fine set of wheels, I guess, right?

          Well, in my town, we have an ordinance that allows the town to tow your car if you park it on the street overnight. They don't usually enforce this until about a week has passed, but the point is still made. I'd imagine the company isn't taking the bikes back to their warehouse every night for storage.

Just because the apples are over priced does that give you the right to steal them. Free market means you also have the right not to buy not to steal.

      It's a "mod" if you do it to YOUR OWN PROPERTY, not if you steal and break into other people's.

      First they stole a bike (one that wasn't locked properly), dismantled it to reverse engineer the mechanism, (in the process depriving the owners of several months' rent the bike might have earned) then went around and opened up over 100 other bikes to reprogram them with their backdoor, and justified this by saying that they thought the work they'd done was worth the cost of several bikes.

      Would this get the same "cool hack", "fun" kind of rating if they'd done it to a similar scheme with cars? Somehow stealing bikes isn't really stealing; I've noticed this in movies where the hero appropriates a parked bike when in a hurry, dumping it on the street when he arrives without a second thought. Cyclists' blood boils when this kind of thing is done to their property; again if you tried it with cars you could easily be killed, and the owner would get a slap on the wrist.

    I found it refreshing that although it was possible, quite a bit of work had to go into hacking the bikes in the first place. The only way to circumvent the system was to physically get inside it and reprogram the firmware. This is solid engineering IMHO.

    Now, if they're really recalled over winter for a once-over, I wonder how much harder they will be to get into when the snow melts and they reappear? Will the Call-A-Bikes become more impenetrable, as Darwinian geek theory dictates they'll need for survival?

    On the flip side, I must also applaud the hackers for not simply vandalising the bikes, but modifying them to return to service once the "free ride" was over. (Perhaps misguided) - theft all the same, but at least free of physical destruction.

    The problem I have with that is that with how often bikes are stolen, vandalised and the initial cost of purchasing them the 6cent per minute might seem costly but appears to be closer to just covering the costs of the service. This is no Robin Hood Hackjob to have those bikes available for free, it's just a way of inching the concept closer to being abandoned by the company. And with by now 10% hacked and this ongoing without publicity for a while they can't honestly claim that it's just for pointing out a security flaw in the system.

      Add in that almost nobody will know the entry code for a free ride, that 9 out of 10 bikes are untouched, the main cost to the 'victim' is the cost of reflashing the hacked bikes. And that wont take too long.

    One of the reasons, I surmise, that this rent-a-bike concept may not work here in the US is because of local mandatory helmet laws [bhsi.org]. I don't know about the European laws. However, I can see why in Europe, helmet use is less of a concern---less cars on the street, more pedestrians, more public transportation-friendly, shorter distances needed to travel from point A to point B. But here in the US, with the SUVs sharing the streets, helmets are a must. And to implement a rent-a-bike system would also mean co-implementation of rent-a-helmet program. But that adds the difficulty of renting the right helmet size, and putting on a helmet that a previous (sweaty) biker was using. So how is the use of helmets handled in Europe anyway?
