I realize the article is yours, but you responded as if you were talking about all pedal-assist electric bikes (as the comment you replied to undoubtedly was), not just your particular model.
Read again: the claim is that these bikes can be hacked. Believe me I tried and reverse engineering is not something that I have a moral block against or so.
Every s-pedelec that I'm aware of is legal to buy and drive on the roads here is locked down. The Bosch system is the one that I now have extensive experience with and the handshake between the controller, the motor and then battery is of a complexity level that I have not managed to crack it despite a serious effort in that direction. Time will tell if I will eventually manage to run my own firmware but right now I'm not hopeful that that will ever happen (I'd love to update the range computation algorithm).
Regular e-bikes (the 25 kph version) are hacked with abandon but even then you are no longer legal (here, in NL and many other european countries). The Bosch system (which has substantial market share in that domain) can be hacked but only at the sensor level, and it's clever enough that it tries to detect such trickery and if it does it will brick itself. The factory diagnostic software contains a field for 'cheat detected' and it's pretty sensitive (to the point that sometimes bikes that have not been modified get flagged).
If you get a supermarket Bafang or other bike, especially older models then you are likely going to be able to hack it, but there too you won't find any s-pedelecs.
The few brands that sell them are all pretty good at locking down their stuff. Build a bike from parts and it's a different story, but then you won't get a license plate, type approval or insurance and your bike won't be legal to drive on the roads.

"These bikes" as in pedelecs in general. Not just ones with Bosch parts, and not just the ones that are available legally as regular "pedelecs" rather than "s-pedelecs" in NL or the EU. In most cases you wouldn't even need to hack them; this is how they work from the store.
