Is there a bike that lasts after extended use?

[Luv2ride]

Does anyone know a brand of ebike which can really go the distance? I read reviews all the time, and my biggest issue with the ebike reviews, is that I can't find any reviews over long term use. I'm sure such a review exists out there somewhere, can someone please direct me?
For the most part, the reviews I read go like this: "Hey, here's this bike I just got it's brand new and rides great."
Or... "Hey, I've been riding this for a whole week and I love it".... Or even the occasional.... "I've had this thing for a few months, I've ridden it on Saturdays and it's awesome."
While these reviews do sometimes give useful information, I'm looking for a review of how the bikes (and their motors and electrical components) hold up after serious long term use.
I've been using an ebike as my primary form of transportation for nearly four years now. When I started doing this, I was living twenty miles away from my workplace with very steep hills in my path. I ride every day.
I've bought only the lower priced ebikes so far.
I realize that with ebikes just as with everything else, you get what you pay for. So Before I go and shell out a higher dollar amount, can anyone recommend from experience, a brand of bike or conversion kit which can handle every day use on and off road for at least two years before a motor or controller box needs to be replaced?
I'm not talking about batteries. I realize batteries will eventually need replaced. I'm cool with that.
I'm not looking for someone who has owned the bike for a couple of years and rides it 2 months out of the year. That does not count That's not really the same as using the bike for a couple of years.
I ride my bike all year, all months, every day. Do any reviews exist of extended use on an ebike?
Please help

I ride my Trek Super Commuter in Southern California year round for pleasure usually 4 to 5 days a week all of my miles are on paved roads.
I have not had any problems with the motor or controller.
This bike is not cheap but has been totally reliable!
