Abstract: A hoverboard includes: a main body including a left main body and a right main body, where the left main body and the right main body are independently tiltable around a center axis of the main body; a left wheel and a right wheel attached to the left main body and the right main body, respectively; a first fender and a second fender attached to a top surface of the main body proximate to the left wheel and the right wheel, respectively; a carrying handle attached to a front side of the main body; at least two speakers at a bottom surface of the main body; a wireless communication circuit configured to be paired with a user device for streaming digital media; and a stereo control panel at the bottom surface of the main body and having a suite of buttons for controlling playback of the digital media.

Abstract: A foldable wagon configurable in a use configuration and a folded configuration includes a frame that is foldable. The frame includes: a front frame assembly; a rear frame assembly; a center linkage disposed laterally between the front frame assembly and the rear frame assembly; an upper pivot bracket; a lower pivot bracket; and a middle pivot bracket disposed vertically between the upper pivot bracket and the lower pivot bracket, where the middle pivot bracket is slidable along the center linkage, where the front frame assembly and the rear frame assembly are pivotally connected to the upper pivot bracket, the lower pivot bracket, and the middle pivot bracket.

Abstract: An electric roller skate system includes a pair of roller skates, where each of the pair of roller skates includes: a base configured to receive a foot of a rider, where the base comprises a front base and a rear base, where a distance between the front base and the rear base is adjustable; a front main body attached to the front base; a rear main body attached to the rear base; an ankle strap attached to the rear main body; two front wheels attached to a bottom of the front base; a rear wheel attached to a bottom of the rear base, where a cross-section of the rear wheel has a barrel shape; a battery; and an electric motor mechanically coupled to the rear wheel.
