You have actually fallen into the classic trap of chasing massive raw spec numbers because your previous budget bikes couldn't handle hills, but a dual-hub setup is actually the exact opposite of what you need. Hub motors operate completely independent of your mechanical gears, meaning if you try to dead-start a 220lb rider up a steep grade from 0mph, a hub motor operates at peak inefficiency and essentially turns all that battery power into heat rather than forward motion. If your genuine goal is to effortlessly launch up a steep hill from a dead stop, you absolutely must abandon hub motors entirely and buy a **Mid-Drive** electric mountain bike. A mid-drive motor directly leverages your physical rear gear cassette; if you shift down into first gear, an 85Nm mid-drive will completely obliterate a 150Nm hub motor on a hill climb because it is mechanically multiplying its torque through your gears. A traditional mid-drive hardtail mountain bike (running standard 29-inch tires instead of sluggish, heavy fat tires) is the undisputed king of "all-around" bikes because it rolls incredibly fast on pavement, absorbs bumps beautifully, and gives you raw, tractor-like pulling power from a dead stop on any hill!
