In the end it will all be sorted.
But I must say that I won’t adopt the same philosophy next time I buy a bike. There are bikes for recreation and there are bikes for transportation. I’m in the second case, and I was counting on some reasonable metrics of efficiency as far as support goes. But I now realize that it’s up to me to store some parts in case of failures. So I think I’ll buy a second wheel. As for the brakes, I’ll swap them out next year because EU law is changing and the rear brake light is going to become mandatory.
If there is one point to take away from this thread it’s that you need to plan very carefully if you want to use an e-bike as a primary or secondary means of transportation. Overall the bike isn’t bad. It’s just a pity that it’s so difficult to keep running.
I’m coming to terms with the fact that my expectation of relying on others to provide maintenance and support simply isn’t realistic.
It is not. I don't know whether you've been bike commuting before this, but this is actually commonplace among bike commuters because, well because local bike shops aren't places that guarantee maintenance and support, especially on the road. By necessity, most bike commuters are relatively self-sufficient, going mostly to their LBS for parts and some convenience services. Many even bleed their own brakes. So when we receive product, we go over everything with a toothbrush and if there's anything we don't like, we simply do not take possession of the product. Taking possession of the product basically means you're going to be maintaining it going forward, generally on your own.
This could definitely and should definitely be improved going forward, but that's normal for LBSs today, and cyclist self-sufficiency is part of why they can continue to operate without much bad blood.
For my part, I have spare tubes, spare tires, spare entire wheels, and a slush fund for repair in case the braking system goes bad. It's exactly the same for when I was commuting using my road bike. Compared to using the car, the car is relatively more maintenance free, but that's primarily because I'm not doing check the oil and water every time I drive (which I should), and I don't do the basic engine check either (which I ideally also should, but my dealer assures me is not necessary).
Of course, I've also never been badly stranded on my bike. I can always pedal it somewhere, and I'm capable of fixing it on my own enough to limp to a bike shop or a bus line. I have been badly stranded with my car - the battery died in the middle of nowhere and I had to call up a towing service to get home. Pros and cons.
