Described herein are systems and apparatuses for securing and locking a ride-able board to a fixed object. In general, a ride-able board may optionally include a planar body configured for moving across a solid surface and for carrying a rider. In general, a ride-able board may include a planar body mounted to a steering apparatus and any number of wheels. In a preferred embodiment, the security device containing a shackle and housing comprising an open cavity is used to secure the board to any fixed object. In a preferred embodiment, the housing cavity slides over the steering apparatus and has two openings for each end of the shackle. The lock secures the shackle in place and prevents the removal of the board from the fixed object. The housing working in conjunction with the u-shackle prevents removal of the locking device from the board.

In one aspect, a modular board exercise system includes a skateboard. The skateboard includes a deck. The deck includes a plurality of hookable portions, and a pair of skateboard trucks coupled with a bottom side of the deck. The skateboard truck includes a pair of skateboard wheels. The system includes a plurality of resistance bands includes an elastic resistance band, a handle coupled with the distal end of the elastic resistance band, and a connecter clip coupled with the proximate end of the elastic resistance band. The connecter clip is attachable to one of the hookable portions. The system includes a stopper base. The stopper base includes a flat pad having a pair of grooves configured to hold each pair of skateboard wheels in a fixed position.

Apparatus and systems are provided that enhance the use of a one wheel skateboard. Some of the apparatus described provide lateral surfaces that engage outer portions of a user's feet. Other apparatus facilitate the engagement of common snowboard bindings to a one wheel skateboard, thereby widening the spectrum of tricks that can be performed.

The invention discloses a torque strengthening device for land surfboard adapters, comprising an upper connecting plate and a lower connecting plate, wherein a number of tension springs are connected between the upper connecting plate and the lower connecting plate; the upper connecting plate and the lower connecting plate are provided with the same number of evenly arranged spring connecting blocks on the side facing the tension springs; the number of the tension springs is twice the number of the spring connecting blocks on the upper connecting plate, and each of the spring connecting blocks is provided with two spring connecting holes; the spring connecting blocks of the upper connecting plate and the spring connecting blocks on the lower connecting plate are alternately arranged. The invention can replace tension springs with different torques to obtain different surfing feelings.

Devices and methods of transport are disclosed. Various embodiments include structural aspects related to steering and changing the direction of conveyances including features which utilize leaning or shifting of weight as part of turning.

A truck assembly having a truck hanger with a flange and a pivot pin extension that may be inserted into a pivot cup of a mounting plate with a well with a pair of complementary fasteners aligning and securing a pair of bushings with a first portion of one bushing disposed within the well to restrain lateral movement of the first bushing when the hanger is tilted relative to the mounting plate whereby deformation of a bore of the bushing relative to one of the fasteners passing therethrough is reduced or eliminated while a second section assists in restoring the hanger back to an untilted orientation relative to the mounting plate.

A multi-wheel truck that minimizes wheel interactions with discontinuous and uneven surfaces. The truck provides a suspension system that absorbs impact force caused by uneven surfaces and a unique attack angle that allows obstacles to be traversed when approached from a wide range of angles.

A personal transportation apparatus (10) in the form of a motorised board (12) including a chassis (14) arranged to support a first foot support portion (16) and a second foot support portion (18) spaced apart from the first foot support portion (16), a first ground engaging arrangement (20) located proximate the first foot support portion (16), and a second ground engaging arrangement (22) located proximate the second foot support portion (18), the first and second ground engaging arrangements (20), (22) being adapted to at least one of slide, rotate and move over a ground surface. At least one of the first and second ground engaging arrangements (20, 22) may include a motive track assembly (24a, 24b) having a roller arrangement (26a, 26b) to rotatably support an endless track (28a, 28b), the roller arrangement (26a, 26b) including a motorised roller (30a, 30b) housing a motor internally of the motorised roller (30a, 30b) so as to drive the endless track (28a, 28b).

The detachable skateboard assembly includes a base part configured for detachable attachment to a board and an upper part configured for detachable attachment to the base part. The upper part is coupled to the base part in such a way that they can pivot relative to each other about a first pivoting axis. The detachable skateboard assembly further includes a wheel unit configured for attachment to the upper part and an elastomeric element arranged between the base part and the upper part such that the elastomeric element is compressed by the pivoting movement between the upper part and the base part. The elastomer element exerts a force tending to make the upper part and base part to recover a neutral position corresponding to the rectilinear displacement of the skateboard.

A skateboard truck includes a metal bolt called a kingpin and a threaded fastener, called a hex nut, which when combined hold the two main components of a truck together: the baseplate, which is mounted to the bottom surface of the skateboard deck; and the turning part of the truck called the hanger, which is mounted onto the baseplate by means of the kingpin, and affixed tightly into the baseplate by means of a threaded hex nut. Two bushings placed along the shaft of the kingpin and on either side of a flange protruding from the hanger hold the hanger in place by the tightening of the kingpin into the threaded shaft nut fastener. The kingpin is oriented such that a threaded portion of the kingpin (on an end opposite a bolt head portion) is generally facing towards a bottom surface of the skateboard deck.
