It's a direct drive motor you picked there. It's going to drag when not powered, because the magnets will inhibit coasting. In fact, someone comments in the Amazon page that it's like riding uphill when there's no power. I suspect most people ride the 1000W motors like motorbikes at 30 mph and don't worry about pedaling. This motor will not go that fast, and it might not climb too well on its own on steeper hills so you will have to help with the pedals. Personally, I have never cared to try a DD motor because I know I'd never ride it much.

I think you're into this for the utility anyway and not for the sport of biking. As long as your battery holds out, the food gets delivered. Direct drive has no moving parts to break like a geared motor so it ought to run and run.
