Embodiments relate to a motorized skateboard. Embodiments allow users to utilize a power supply, such as a rechargeable battery pack, that is remote with respect to the skateboard. Embodiments can have the battery mounted on, under, partially or wholly enclosed within, and/or integral with the skateboard deck. Embodiments can have a removable and interchangeable motor mount, which attaches to the hanger to align the motor with the drive train. The drive wheel adaptor (hub) allows the user to modify standard skateboard wheels to use as drive wheels for the electric skateboard. The strength of the bond between the drive hub and the wheel enables the skateboard to utilize more torque without failure. Embodiments can allow users to have wiring connections at the front and/or back of the skateboard deck. Board-integrated wiring techniques can also be utilized. The electronics can be attached using brackets that fit the industry standard bolt pattern.

Electric vehicles, electric vehicle systems, and methods for controlling the electric vehicles or electric vehicle systems are described. In one implementation, an electric vehicle includes a main body for carrying a user, a plurality of electric wheels mounted on the main body, and a controller mounted on the main body. The main body includes a front main body and a rear main body removably connected to the front main body. The front main body can move independently when disconnected from the rear main body. In some embodiments, at least one of the plurality of electric wheels is mounted on the front main body. The controller is configured to send drive signals to the plurality of electric wheels according to input of the user. The plurality of electric wheels are configured to rotate according to the drive signals. The electric vehicles and the electric vehicle systems described in the present disclosure have a separable main body, advantageously allowing for short or medium distance transportation at low cost, flexibility in turning, and great potential for expanding their functionality.

Examples of the present disclosure are related to systems and methods for an attachment for a stroller, walker, wheelchair, ambulation device, or other transportation device. More particularly, embodiments relate to a wheeled board that is configured to be coupled to an axle and a support of the transportation device, wherein a lower clamp connected to the axle is positioned orthogonal to an upper clamp coupled to the support of the transportation device.

Methods and systems are provided for concave footpads for a personal transport device. In one example, the concave footpads may be coupled to the personal transport device, arranged between an operator's feet and an upper surface of the personal transport device, the upper surface including a pressure transducer.

A stand for a skateboard or other board that is capable of folding flat for shipping, storage, and store display of the stand, but that can be folded into a three-dimensional shape capable of holding a skateboard upright, either vertically or horizontally, for storage and/or for display of the skateboard.

A device that secures an object to the user's body, hands free, while carrying multiple types of bulky items is provided. The carrying device may include at least a pair of first straps and a second strap having a plurality of loops spaced apart along its length. Each strap terminates at opposing ends providing complementary and adjustable connectors, so that when each of the two first straps selectively engages one loop of the plurality the loops, many different types of bulky items may be secured to the body of user when the connectors are locked, thereby leaving the user hands free while transporting bulky objects.

This invention provides the novel application of securing a low friction polymer, such as, for example, UHMWPE as the exemplary embodiment, with a coefficient of friction of less than about 0.15, which has adjustable margins for length, height, and width, on the bottom of a skateboard, between the bottom of the skateboard and the wheels with the purpose of mitigating the problem of wheel bite in skateboarding. This piece may have a flat or shaped, concave surface, and can be attached to the skateboard with an adhesive, by embedding the material in the skateboard, or by other known methods.

A board mount system is provided for securely mounting an action sports accessory with a sports board by securing a base mount with the sports board, the base mount including an interlocking opening for rotatably attaching interchangeable adapters that are attached to or incorporated with the action sports accessory, such as a camera, gimbal, hook, shelf, handle or secure cover. The base mount may be secured physically or magnetically to the board via screws or magnets positioned at peripheral corners of the base mount within cylindrical housings which interface directly with a surface of the board, while a mount surface of the base mount is connected with a top portion of the cylindrical housings so that the mount surface is raised above the surface of the board to allow the adapters to securely fit into the interlocking opening or in a space between the mount surface and the board.

Systems, methods, and computer program products which facilitate the ability of a user to monitor and assess the location of and forces transferred to various joints, muscles, and limbs and their relative positions at each and every moment during normal daily activities, training loads of an exercise, or a competitive or high intensity athletic endeavors, in order to mitigate and reduce the risk of injury as well as to track fitness performance elements are disclosed. In an aspect, systems, methods, and computer program products are disclosed which utilize at least one sensor in order to capture a user's movement information during various tasks and exercises. This movement information may then be analyzed in order to determine quantifiable values for the user's likelihood of experiencing an injury and/or the user's overall fitness, generally. The systems, methods, and computer program products of the present disclosure may also be used to measure a user's neuromuscular efficiency and help the user make improvements thereto.
