Abstract: One variation of a system includes: a cam block mounted to a deck of a scooter and defining cam lobes arranged about a pivot feature and cam heels between the set of cam lobes; a pivot block pivotably coupled to the pivot feature and defining followers riding over the cam lobes; a pair of wheel uprights locating a pair of wheel assemblies; a first lateral link extending between and coupled to the pair of wheel uprights and pivotably coupled to the pivot block; a second lateral link extending between and coupled to the pair of wheel uprights, vertically offset from the first lateral link, and coupled to the pivot block between pair of wheel uprights; and a spring element driving the followers of the pivot block into cam heels to bias the second lateral link toward a neutral position.

Abstract: A tri-mode collapsible scooter includes: a deck; a stem; handlebars; a head tube; a neck hinge; a deck hinge; a wheelset; a neck control; and a deck control. The deck includes: a front deck section; a rear deck section; and a deck hinge interposed between the front deck section and the rear deck section. The neck control is configured to release the neck hinge for transition between an open neck position and a closed neck position. The deck control is configured to release the deck hinge for transition of the deck between an open deck position and a closed deck position. The deck hinge occupies the open deck position and the neck hinge occupies the open neck position in a ride mode; and the deck hinge occupies the closed deck position and the neck hinge occupies the closed neck position in a tow mode.
