I was going to say scoots are fairly light, but then I decided to make sure.  The closest I got was one reference for travel scoots:  Travel scooters are easy to lift into the trunk, with the heaviest piece on some models weighing as little as 22 pounds.  Every other mention of weight is a reference to the user's weight. (3-wheel scoots for up to 350 lb., 4-wheels for up to 500 lb. Source: SpinLife)
