I have a 2020 Mini, it'll scoot along up to 25 mph in high gear (I'm 185lbs). I get up to 35 miles per charge as well. The mechanics on it are pretty simple, and uses some off the shelf parts. It's similar to high end lipo powered rc vehicles, need to take care of the batteries, I like it for cruising on weekend mornings when the streets are desolated and park trails.
