Abstract: A three wheeled scooter comprises a chassis having forward and aft ends with a front wheel non-pivotally mounted to the forward end and a pair of rear wheels coaxially mounted to the aft end. The chassis defines a longitudinal axis and includes a support assembly and a handle assembly extending upwardly from the support assembly. The rear wheels are configured to be angularly yawable relative to the longitudinal axis between a neutral position and a yawed position. Steering of the scooter is thereby effectuated by angular yawing of the rear wheels relative to the longitudinal axis such as by asymmetric loading of one of opposing sides of the support assembly.

Abstract: A scooter is disclosed which positions a center of gravity of a rider toward the front the scooter so that the rider can more easily perform a 180 degree turn trick. Since the rider is positioned closer to the front wheel, it becomes easier for the rider to flip over the handlebars. Fortunately, the scooter reduces a moment arm that defines a deceleration moment to reduce the likelihood that the rider will flip over the front handlebars.

Abstract: A truck assembly for a vehicle such as a skateboard or scooter may have a kingpin about which a hanger rotates. The hanger may be biased toward a caming surface having a depressed configuration by a spring, weight of the rider and also via a centrifugal force created during turning. This aids in dynamically stabilizing the truck assembly and the vehicle to which the truck assembly is mounted based on the particular rider and the maneuver being performed on the vehicle. The caming surface may have a regressive configuration such that the spring compresses at a different rate per degree of rotation of the hanger.

Abstract: A skate truck is disclosed which provides for a wide yaw angle for a hanger, minimal friction during yawing of the hanger, and a suspension that is dynamically stabilized based on a weight of a rider and a turn radius of a vehicle to which the skate truck is mounted. Additionally, a tension of the skate truck can be adjusted by preloading a spring which accommodates a wide weight ranger of riders. The truck may have a hanger supported between two bearings, namely, a sliding bearing system and a thrust bearing. The sliding bearings slide within grooves that define a pivot axis of the hanger. The grooves can also have various customized ramp profiles to provide a different feel during turning of the vehicle.
