it took 10 years to work out how to recell a bosch bms and it can only be done if it is working and charging.
problem is they wont sell the parts not even the bearings to make them a throw away item they was never made to be repaired like shitmano not even peter will touch those things again.
when things use chips that need pairing to the device like apple crap even oem parts wont work without it.
lbs wants 50 quid to plug my bike in and im not allowed to buy the software not that you can do much with it anyway because it is just a dongle to connect to the bosch server.
get a Tesla and change every part with oem ones you can buy and try fit it ur self fkn no chance!
Again, I think all that will change as business, especially given competition in this growing market, will force companies like Bosch to offer spares, as they do already with their power tools, which is a gigantic market with equally huge degree of competition.
Theres something else thats about to change, though not bikey related but woodworking machinery orientated.
Currently, you can buy basic table saws from B&Q for under a hundred quid, and semi pro/trade ones for 450-800. But theres a company called Sawstop, which offers a saw with flesh sensing technology that makes it near impossible to amputate your fingers in a hand/blade accident.
Prior they were not available in the UK or Europe, but thats about to change, and they're going to offer a basic saw for 900 for the UK market.
This will force all the other makers - Bosch,Dewalt,Makita to follow suit, given many of their 'trade' saws are not far off that price, and the customer will be given the choice of buying Sawstop with its safety feature or saving a couple of hundred quid and risk amputating half their hand should an accident occur(which they do on a disturbingly regular basis)
If they don't, they risk losing their position in that market, and a massive downturn is sales, especially amongst the home hobby user right through to trade and even professions(other saws they will be offering at £1400-£3k(you might think thats a lot, but I paid £1200 for my saw, which is a higher end 'hobby' type) and given the choice will be snapping up a basic sawstop for home use as opposed to any other, no matter how good a deal it is.
Prior to selling here the only other company selling a saw with sawstop technology is Festool, which is owned by the same parent company as sawstop and that was going to be the one i was originally aiming to buy, which was £2100 for ther basic model.
So now it's F*** festool, im having a Sawstop, plus im saving £1200.
I see the same circumstances happening with ebikes, especially the higher end models built by the big companies. If someone is spending 3,4 or 5+ grand, and they're going to be better informed, they are going to choose the one which will given them what they want, and have options should it need to be repaired.
