i wondering if one of you never try it? to your opinion does an adult could run 15 miles/kilometres on this?
because it's the most smart self propelling scooter than i never seen,indeed i was walking at the side of a river in my area a few years ago ,and i seen a growned up adult man on this ,but i was probably more a TRIKKE scooter
it's one of the best invention than i seen since a very long time
