On the flip side, we bought my other half a used (out of warranty) Levo a couple of years ago and it’s been fine. Granted, it doesn’t get ridden through the winter in horrific conditions but she’s had no problems with it.
The motors aren’t some impenetrable wizardry – they use belts, gears and bearings – and are assembled by normal humans. If they can be built by people, they can be repaired. Batteries can be taken apart and repacked if absolutely necessary. Depending on how technically-minded you are, of course, YMMV..
