I’ve been following this thread for a couple years now and have myself been trying to figure this out. I’m a fan of using stock components, mostly because I enjoy a good challenge. I’ve of course replace the controller with a third-party one, which is not a challenge. But getting the stock controller to work as personal, has proved to be difficult. I’m surprised nobody has noticed this yet, and also, I’m pretty sure the PCB that has the speaker and lights attached to it as well as a Bluetooth module is actually more than that. If you notice the PCB has the word key on it. With two contacts. With a Orange and gray wire. If you follow the orange and gray wire they go nowhere it seems. But, they change color in the cable somewhere. I hooked up a multimeter to it set to Measure resistance. Something fascinating happened. For a split second when you first connect the two to the meter, a random voltage shows up. For example, 0.194 Ω or 0.398 Ω. I’m pretty sure this is some sort of a random number generator to create some sort of verification code that is provided by the app or something to unlock the bike. I’m also surprised nobody has looked into the SIM card and the phone number that only supports texting over the Jersey telecom network. I’d be curious to put the Sim card into a phone and then try and rent a bike and see what kind of message comes through. And then see if it somehow corresponds with this Key number that is generated in the speaker PCB. Anyways, just some of my observations and I’m surprised there’s 36 pages in the thread and nobody’s mentioned any of these yet.
