So I had a quick look for one, and I wouldn't even say elaborate scooter, it's just a scooter. Yea it has bigger wheels which use actual tyres and tubes, but that's the only real difference.

The one I checked out was around 10kg, so not super light or anything(heavier than my bikes, but granted they cost significantly more). You aren't going to be more efficient than a bike, it is going to suck when you get to any climb.

These definitely aren't for me, or anyone in my area(too many hills), a bike is the significantly better option.
