Bosch motor alternative

[EddySW]

Dear all
My first post so hope it starts a good discussion. I was recommended your forum by another member...

I have a beautiful Riesse and Muller ebike with a Bosch motor. It's out of warranty and broken and I have the option to buy another Bosch motor for £600ish. I'm a bit / lot vexed about not being able to replace a torque sensor, a job that seems to me should be fairly simple - not a £600 job. With this vexed-ness (sp) I would love to consider keeping my bike but being free from Bosch. I see Bafang are now making motors that require frames to be built around the motor - like this: https://www.bafang-e.com/en/components/component/motor/mm-g530200.html . This seems to be a mounting bracket: https://www.bafang-e.com/en/components/component/accessoires/fp-g530.html

Has anyone thought about how these motors could be fitted to Bosch designed frames. It strikes me that as these bikes age there are going to be many more vexed bike owners like me with bikes out of waranty that with problems that currently require a new motor at £600ish.

Also in the light of warranties being invalidated as the latest Bosch software detects the use of "tampering" devices, there must be potential huge interest in fitting "open source" motors to Bosch designed frames. (please no discussion on ethics / law as many people, like me have fitted such devices just for off road fun).

I really appreciate any help working out if this is possible.

Can anyone help create an adapter?

Best

Can't your motor be repaired? FWIW, I've heard that all the OEM systems are proprietary, and haven't seen a situation in which another company makes a motor that will fit an OEM frame.

How long did you own the ebike before it died?
The problem with proprietary is you could end up with a two wheeled paperweight. Is it still a pedelable bike that can be ridden as is with the dead motor? Does it pedal without the drag of the motor? A conversion to add a normal bottom bracket might be an idea then go from there, keep it a pedal only bike or add a bottom bracket mounted mid drive. Probably makes more sense to count your losses and move on. I’d hate to have a store selling this stuff and have to tell my customers the unfortunate truth about getting there ebike fixed, think they’d be pissed this sort of thing wasn't mentioned before the sale. One word, repairability. Yes or no. I don’t mean chains or tubes here. A lot of things are just not built to last anymore, unfixable due to the manufacturing process or untrained service staff/replacement parts or whatever. One reason DIY has its advantages.
