An assembly for a motorcycle is disclosed which can adjust rake angle and trail on a motorcycle. The assembly includes an inner housing which engages with an outer housing. The outer housing attaches to the frame of a motorcycle. The assembly also includes a pair of forks capable of supporting an axle on which a front wheel is mounted. The assembly further includes a pair of brackets, each secured the pair of forks. Each of the pair of brackets including a pie shaped portion having a first edge secured to one of the pair of forks, and each of the pair of brackets having at least three spaced apart grooves formed therein for receiving the axle. The rake angle and trail of the motorcycle can be changed by adjusting the position of the inner housing to the outer housing and by positioning the axle across the pair of brackets.

Examples of the present disclosure relate to a bicycle configured to easily and efficiently adapt for riders of different sizes while providing both balance bike and pedal bike functionality. An exemplary bicycle is a children's bicycle designed and developed to grow with a child. An exemplary bicycle is configured to enable utility adjustments to a front assembly, among other components, which creates a setup that comfortably accommodates either smaller riders or larger-sized riders. The bicycle is adjustable with minimal effort and without tools, enabling re-configuration on the fly. Further disclosed is an exemplary training wheel device that is attachable to an exemplary bicycle. An exemplary training wheel device extends functionality of the bicycle and assist with training a young child to ride the bicycle.

A motorized scooter that may be reversibly converted into a push-cart, which may be powered or non-powered. Converting to a push-cart may include shortening a wheel base and/or tilting a steering column backward and/or extending a steering handle backward.

A tricycle has a forward oriented fork member (20) supported for rotation about a steering axis (14) of the tricycle, a handle bar (50) mounted to the fork member, a cargo unit (24) supported by the fork member, and a pair of transversally spaced linkages (30), wherein each linkage at a proximal end is linked to the fork member and at a distal end supports a respective front wheel (16) of the tricycle. The cargo unit and the linkages are shiftable between respective forward and backward end positions to thereby transform the tricycle to a wheel cart and vice versa.
