Wattbike Atom Gen 1 - For Parts/Repair

I’ve a Gen1 Wattbike Atom with a blown main board. The board is going to cost me about €400-€500 so isn’t worth replacing (in my opinion). I mistakingly plugged in a 24v adapter and blew it. It’s probably repairable by somebody who is good with electronics. I’ve tested with a multimeter. The board isn’t physically damaged or burned but it’s not getting 12v past the red connector where the power plugs onto the board. ChatGPT tells me I’ve blown the diode. Alternatively, if anybody needs a bike for parts then it’s perfect. I’m open to offers for the full bike, I’m not interested in stripping it for parts.
