That is an absolute valid concern and unfortunately, most reviews would not even exist or only half the models tested, if you were to write a second “that went wrong”, if you cannot distribute the scooters and have them ridden (if you do not have to return them after your initial review).
My Gotrax´ stem is a bit tilted, but still works. I actually did abuse that thing with respect to its slow 14-15 mph topspeed, minimum 1000 km on it and have yet to wear down the second pair of (this time solid) tyres. So, i was lucky. And i am aware that it is way more bothersome and annoying if a really expensive one breaks down, especially with higher quality in mind.
I draw the parallel to computers: the PSU (power supply unit) is what keeps the thing running, the most important part, but even there, only slightly the “max powaaa” is reported (not showing if max combined, 12V or if it is a 30 year old design with 3.3+ and 5V+ a major thing or if it even lives up to the specs, see burning gigabyte PSUs).
Anyways: Yes, long term is important and quality is mentioned by the peeps here, but it is not a sexy factor to sell. “but this one has 10% higher range” vs. “but it has a higher quality”. Myself i fall into the specs trap once in a while, this is why i tell everyone to not just buy a scooter off Amazon if there is not at least a trustworthy review available. Long-term would be even better. If not only longterm, maybe revisiting after 1000 km, if feasible. I see how my range dwindled a bit, bit that is mostly tyres and now i think the battery is starting to degrade a bit, also, but within reason and usage and not catastrophically.
