Who wins eBike Hill Climb Challenge? RadCity 5 Plus, Ride1Up 700, Aventon 500 or Ecotric Leopard

I torture test 4 eBikes to determine who has the best hill climbing capability. Motor watts plus torque should be a good proxy but does that translate to the real world? Only one of these bikes will be the winner. All of these bikes were purchased, I have no affiliation with the manufacturers nor any financial interest whatsoever. Why did I do this test? I wanted a bike that can handle my commute that contains a hillacious incline. I've seen every YouTube video made and with the exception of EBR very few have an objective hill climb comparison. The published specs are inconsistent at best and even worse, due to supply chain issues (at least I'll assume that for the sake of being positive) manufacturers are swapping parts without changing their published specs. Not trivial parts, but motors, shifters and more. See for yourself which one of these bikes is the best.
