I get that derestricting an ebike voids the warranty and may contravene local laws; but if the bike has been sold in entirety to the consumer (not leased/rented/hired etc), I fail to understand how Bosch can legally prevent a bike from working through throwing a 504 error meaning a dealer visit is required or a bizarre workaround involving riding the bike without motor support or connecting it to a power drill.
It may exist, but I've never heard of where Bosch have an acceptable use policy for ebike motors (except the warranty policy which only legally applies to the warranty/support of said bike not the ride-ability) which the rider has to agree to prior to getting on the bike.
If the bike is wholly owned by the consumer post purchase, surely the legal liabilities of riding an derestricted ebike are that of the owner not Bosch; so the owner just accepts that:
1. Any legal proceedings/police intervention etc are nothing to do with Bosch.
2. The warranty on the motor is null and void and through software/dealer/other Bosch will keep a record of said modifications.
I'm no legal expert but the whole disabling the bike approach is bonkers in my mind. If country has a law where Bosch are legally held accountable, then surely this approach should be limited to said country rather than worldwide.
Take the car industry, you can remap engines to unleash the power that the standard map holds back. In the UK it voids the warranty on the car, usually flags a report with the central systems (in VW case its the TD1 flag for example), and you legally have to inform the insurance company of said modification to remain legally compliant. But car manufacturers don't suddenly cut out the car mid journey and leave you stranded.
