    Citi Bikes have GPS trackers. The police should be able to identify
    the shooter from the credit card used to pay for the bike rental.

    As I understand it, the currently preferred NYC method is to
    remove and swap the square-block optical code stickers.

    Thief stands astride one bike until, a few feet away, random
    customer scans the other bike. Thief rides away before
    customer gets a clue.

    I assume there are other methods because rental e-bikes used
    by criminals is not rare.

    Are they docked or dockless? The dockless bikes folks just ride them, and
    can hear the clicking from the brake, tends to be more that they get left
    in awkward spots and are remarkably awkward to move!

    The problems were with the Gen 1 stick on labels:

    In Aug 2021, we had:
    "Scam uses swapped stickers to steal ride-share bicycles:" <https://apnews.com/article/lifestyle-nyc-state-wire-34d4ecd5dcd3821ddd6e9a308834a16b>

    At some unknown year, the QR code was (laser?) printed on the Gen 2
    display: <https://www.reddit.com/r/NYCbike/comments/14vcwmp/2nd_gen_citibike_ebikes_have_the_bike_id_on/>
    The serial number is also on the stem.

    Probably in frustration, the free ride thieves have resorted to
    defacing the code, which doesn't give them a free ride, but does force
    the customer to type in the bicycle serial number on the app. Of
    course, they could deface all the places where the serial number might
    appear, but that still doesn't give them a free ride.

    "Why Are Citi Bike’s Electric Bikes Always Broken?" (July, 2023) <https://www.curbed.com/2023/07/citi-bikes-electric-bikes-lyft-broken-maintenance-batteries.html>
    "The QR code issues have also been halved, a spokesperson said, with
    measures like displaying the bike number on the console, which allows
    people to manually take out bikes on the app."

    Ah very much like London’s “Boris Bikes” which I’ve used once, but for me
    there is way too much london to get though before I get to a docking
    station, and generally prefer to take my own bike or get the train as both
    are more convenient.

    Do very rarely see a stolen bike, hand painted or dumped. I suspect they
    are more difficult to steal than the lime and other dockless bikes that are frequently being used with the lock engaged hence the clicking letting
    folks know that sir is a cad!

    How does dumping the Divvy bike in the lake give someone a free ride?
    That's about as useful as defacing the QR code or serial number. I
    haven't seen any mention in the alarmist press on the use of RFID tags
    commonly used to track the bicycles through the manufacturing process.
    However, there are a fair number of hints found with a Google search: <https://www.google.com/search?q=bike%20share%20RFID%20chip&udm=14>
    "RFID ON THE MOVE" <https://nabsa.net/wp-content/uploads/2017/09/RFID-on-the-Move-Guide-to-User-Authentication-and-Access-Control-for-Bike-Sharing.pdf>

    Somehow, I'm not alarmed by the possibility of being poisoned by a
    submerged eBike. Lake Michigan is a fresh water lake, so there will
    be less corrosion damage. Corrosion damage plus water incursion into
    the battery will not start a fire because the lake water will cool the
    battery to well below the point where thermal runaway becomes a
    problem.

    Sealed eBike LiIon battery packs do not seem to be rated for "Ingress Protection", so I can't guess their level of waterproofing: <https://en.wikipedia.org/wiki/IP_code>
    The typical 18650 cell does have a pressure relief valve, which is
    small enough to pass gasses, but block water. Maybe in deep water,
    but not near shore as in the video.

    The NBC YouTube video clip lacks any kind of relevant numbers, such as
    the number of Divvy bikes recovered from Lake Michigan. I also tried
    to find what might be contaminating the water and what constitutes a
    hazard. I gave up after 15 mins. It's much like radioactive
    contamination from Fukushima, where the concentration is so low that
    laboratory measurement is very difficult. I'm fairly sure that
    ingesting an 18650 cell isn't particularly healthy. I'll wait for the inevitable litigation and the obligatory "Do Not Eat" sticker on the
    batteries and battery packs.

    If Divvy kept a record of rented that bike just before it morphed into
    a submersible vehicle, they could find the evil bicycle thieves.
