They look indeed hard to service. Way too many screws, hidden cables, and propriety parts.
I’m currently looking for a non e-bike as my 2nd runner, and I compared their mountain ebikes with the treks and they look so much cleaner and easier to service.
Does your friend have a cheap e-bike?
Also, does it work at 3AM when bakers usually start working?

Silence since then.

Edit: I skimmed through the study and their premise is to combine 3 crystals and break the linearity of the cristals to get a better response and better responsivity over the whole bandwidth of the light spectrum. It seems to be stable at a wide range of temperatures.
Issue is, they broke (or combined ?) the cristals with a microscopic needle but that isn’t feasible for mass adoption, so they speculate that some rust process might be the best approach to try.
I’m no scientist and it’s likely very false what I stated, but I think the premise is that we need to find ways to create panels with broken up cristals to give them more power.
