Disagree, unless you are an incompetent and cannot service your own bike for minor issues. Owning an e-bike implies some level of ability to use common hand tools and knowledge of how to maintain and fix simple things. If you can't do that you probably shouldn't be purchasing an ebike.
The cheapest ebike at the local shops near me were 2-3x what I paid for my entry-level Chinese ebike. Maybe I got lucky but in the 2000 miles I've had it (since last July), it's been flawless. I swapped out the tires, tweaked the settings to my liking, changed the saddle, added a riser, and a few other mods. It's not rocket science.
I did take my wife's 26" rear wheel from her Schwinn trike to a LBS to true up the spokes. They charged $35, which I thought was WAY overpriced.
