An apparatus for automatically adjusting tension on retention member to hold multiple objects together. Examples include using retention apparatus to obtain optimal fit and use of a human wearable item such as article of footwear. Sensors may be used to sense changes in movement of the article of footwear, of the person wearing it, or of a third object such as a vehicle carrying the person. A retention member may surround at least a portion of the objects, and an actuator may be included that automatically rotates a rotating member such as a gear or pulley that may be coupled to the retention member. The rotating member may be configured to automatically adjust tension on the retention member many times per second based on control signals from control logic responsive to the sensors.

An apparatus comprising a platform; a plurality of trucks coupled to the platform; and a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation, wherein the roller assembly is configured for an elastic biasing, wherein the roller assembly is driven by a motor.

A pair of foot lift attachments for attachment to single-wheel motorized electric skateboards, and combinations thereof. The foot lift attachments include a right foot lift attachment and a left foot lift attachment, each having a first concave curved outer facing side wall configured to be engaged on a curved support surface of either of a fender covering the single wheel, or a curved support surface of a mounting bracket secured at each side of the opening for the single wheel, and each having a convex curved top end wall with a concave curved underside configured to laterally receive and overlap the medial side and a top portion of the skateboard rider's foot and footwear worn on the foot to enable the rider to lift the skateboard off the ground with their feet and perform freestyle skateboarding maneuvers and aerial moves and jumps.

A sport board system is provided, the system having a sport board deck having a bottom surface, a front end and a rear end, a rear wheel assembly fixed to the bottom surface adjacent the rear end, and a fixation structure for a wheel assembly at the front end. The fixation structure has a notch passing through a thickness of the sport board deck, fixation rails parallel to a length of the sport board deck, and a locking mechanism at an end of the notch. Also provided is a method for transforming a sport board system from a skateboard configuration to a scooter configuration.

Mobilized platforms are disclosed herein. The mobilized platforms can include a first fork hanger attached to a platform at a first platform end with a first cog-hub assembly attached thereto and a second fork hanger attached to the platform at a second platform end with a second cog-hub assembly attached thereto. The fork hangers can be attached to the cog-hub assemblies such that each fork hanger is attached to a cob-hub assembly at both a first cog-hub assembly end and a second cog- hub assembly end opposite said first cog-hub assembly end. The mobilized platforms can include additional features such as baseplates or transom plates. The cog-hub assemblies can also comprise wheel assemblies or connected cog-hub subassemblies. The mobilized platforms can also include a treading connected to the cog-hub assemblies.

A quick-release truck system includes a deck plate, a truck plate, and a locking mechanism for releasably locking the truck plate to the deck plate. The deck plate mounts to an underside of a deck of a rideable vehicle, and the truck plate mounts to, or is integrated into, an upper surface of a truck baseplate. The deck plate and the truck plate slidingly engage one another using vertically-staggered complementary coupling means. The coupling means may further be horizontally-staggered to create a tiered configuration. The coupling means include a combination of rails and grooves. Once fully engaged, the truck plate releasably locks to the deck plate. The deck plate and the truck plate may include cut-outs for weight reduction.

A skateboard that can be converted between a scooter and a skateboard has a bracket that is pivotably mounted on the footboard and can be pivoted between a first scooter position and a second skateboard position. The bracket is longer than the footboard by an amount, so that, in the skateboard position, the bracket forms a clearance between itself and the end of the footboard that is sufficiently large as to enable the skateboard to be gripped through said clearance and carried.

A skateboard deck lamp is presented. The skateboard deck lamp includes a deck comprising truck holes, a standing surface, an underside surface. The truck holes were originally intended to couple the deck to a wheel axle truck assembly. The skateboard deck lamp also includes a truck assembly coupled to the underside surface. The truck assembly includes a base plate and a central portion. The base plate includes openings aligned with the truck holes, and the central portion includes a socket for receiving a light source. The skateboard deck lamp also includes a power supply conduit coupled to the standing surface. The power supply conduit receives electricity from a power source. The skateboard deck lamp also includes a lamp wire coupled with the power supply conduit and the socket via at least one truck hole of the truck holes.
