I am curious as well. As a big fan of manual kick scooters, this quality/ability is important to me. Do they all pretty much require the walk of shame for anything beyond a few hundred feet? Or can some actually be propelled manually for a mile or more without exerting great effort or suffering considerable discomfort? Many electric bicycles have the benefit of offering some level of exercise, do some scooters as well?
Many of the budget oriented, lower end breed of electric scooters would probably be best suited to this task. I would think that most intermediate level and higher electric scooters do not accommodate themselves well to this, if for no other reason than that the typical platform height of 7 to 12 inches or so forces unduly flexing of the onboard knee. Also, internal resistance from the motors could be a factor. And then there is the actual weight of the scooter. Imagine trying to do this on one of the Wolfs. Scooters such as the Ox, with one motor, reasonable weight, and an adjustable suspension able to lower the platform, might be candidates here.
