An exercise apparatus and a method thereof relate to the technical fields of physical exercise, training instruments, life cultivation and health preservation, leisure and entertainment, teaching appliances, smart home and the like. Through reverse thinking, by changing a shape, a structure, a function, a control method or/and a using method of an electric scooter, the electric scooter is switched to the fields of physical exercise or/and learning and education. By means of technical characteristics in an attempt to avoid by the technical staff, unexpected technical effects are achieved, and a new purpose of the electric scooter is achieved. The exercise apparatus carries a user to perform automatic round-trip movement, the user correspondingly adjusts physical and mental states to prevent from falling and the exercise apparatus is helpful for improving abilities of balancing, coordination, relaxation, flexibility, concentration and contingency of the user.

A rack to hold skateboards, longboards, scooters, motorcycle helmets, purses, umbrellas and other implements or accessories. The rack is adapted to be mounted on a wall or surface. The rack is formed of a lip extending from a rear support. The lip is formed of a series of rounded protrusions. Items to be held by the rack can be received over the protrusions. In one embodiment, each protrusion is angled at a predetermined angle from the front. This helps keep a received skateboard, scooter or other accessory at an appropriate angle such that the wheels or surface of the accessory will remain off an affixed wall to avoid damage to wall. The rack can also include a locking mechanism for locking adjacent protrusions. The rack is designed for safety by having rounded edges on all areas that protrude from the wall.

A backpack has a folding durable panel attached to the back side thereof. The panel is configured to wrap around a middle portion of a skateboard deck, such that the trucks and wheels positioned away from the back of the wearer. The skateboard is secured to the backpack by an attachment means attached to the ends of the fabric panel.

Wireless signal light systems for vehicles, including wireless illuminated gear and clothing, are provided. In an example system, a wireless transmitter is communicatively coupled to a motorcycle or other vehicle. Receivers in illuminated articles, such as helmet, backpack, jacket, vest, race suit, gloves, boots, and other gear receive signaling information from the transmitter, such as left and right turn signaling and braking of the motorcycle or vehicle. Colored LEDs or other lighting in the illuminated articles mirror the signaling of the motorcycle or vehicle. Left and right gloves and boots may have respective left and right LED turn signal indicators. A pushbutton on each illuminated article synchs the article with the signaling system of the vehicle. The illuminated articles and can sense an emergency through position or by separation from the vehicle and activate emergency flashers, sound, and emergency contacts through a phone. The system batteries also have hazard protection.

A skateboard tool having a fastener-engaging piece and a nut-engaging piece which work cooperatively to unscrew multiple fasteners simultaneously. The fastener-engaging piece has a handle and a body. The handle is rigidly connected to a shaft which extends into the body and is rotatably connected with a set of interconnected gears. The handle and shaft are rotatable with respect to the body. The body also includes a plurality of fastener-engaging bits that are rotatably driven by the gears. The handle and shaft are rotated, which in turn rotates the gears and rotates the fastener-engaging bits. There is also provided a wrench for engaging, and rotatably locking, nuts secured to the fasteners that are rotated by the fastener-engaging bits. The wrench has an elongated U-shaped body having a pair of legs and a connector base piece. Each of the legs includes at least one nut-receiving socket.

A skateboard carrying device is disclosed that is a multipurpose storage and transportation device for skateboards. The skateboard carrying device comprises a body component that is configured in a plurality of straps worn around the torso and back of a user, like a backpack. Specifically, two nylon straps are applied to a user as a waist strap, with a third strap being secured up over a user's shoulder. Additionally, four additional straps are secured to the third strap to secure a skateboard thereto. The straps can be secured via hook and loop fasteners or a buckle, etc. Users can carry their skateboard like a backpack to keep their arms and hands-free while traveling and transporting a skateboard.

A skateboard tool system (100) may comprise a first arm (200), a second arm (300), a third arm (400) attached to a body (500) with each arm forming an overall T shape and each arm having a distal end attached to a useful implement. To gain mechanical advantage, the body (500) may contain or be integrated with a rethreading tool (540). The centralized location of the re-threading tool in combination with the T shape allows for a superior purchase or grip while rotating the re-threading tool. The body may define various voids to comport with a unique L shaped screw driver (600), the screw driver having a shorter (605) and a longer (607) longitudinal member giving additional leverage in rotating a Phillip head screw driver (610). A cutting blade is retained within the body for ease of access and safety.
