A skateboard with hand brake comprises a skateboard, a handle and a hand brake.

A skateboard can be an ordinary skateboard or an electric motor skateboard.

The handlebar has an L shape.

The end of the lower part of the handle is fitted to the hanger of the front truck of the skateboard.

A hand brake comprises a brake lever, a brake cable and a brake module.

A brake lever is fitted to the upper part of the handle and a brake cable connects the brake lever to the brake module that is fitted underneath the deck.

What is new about this inventions is that it does not use the wheels for any stopping. The nature of the technical disclosure of my invention is that when a person of any weight were to put pressure of the back of a skateboard where are described brake is attached it will slow now and/or stop depending up weight and pressure. It will not get in the way of any skateboard tricks as it is sloped from 0 to 1 inch in height. If one puts all their weight on one foot at the back of the board it will stop and just a few feet regardless of weight of boarder. A Google search shows the US has 11 million skateboards who have an average of two boards. We can retrofit approximately 85% of the existing boards and hopefully save many hospital emergency calls and the average of 4.3 skateboard deaths per year. A google search shows an average 64,500 emergency skateboard visits per year.

An easy-wearing skate is provided, wherein the easy-wearing skate includes a boot having a chamber open upward, the boot further includes a fixed shell having a rear opening, and a movable shell rotatably connected to the fixed shell and configured to cover the rear opening, the movable shell is swingable away from the rear opening, a first tightening strap is connected to a side of the fixed shell, a locking device is connected to another side of the fixed shell, the first tightening strap is releasably locked by the locking device, and as the first tightening strap is released from the locking device, the movable shell can swing away relative to the fixed shell.

A wearable mobility device comprising a base for the placement of a shoe, the base including a heel-support section, a battery pack, a tail reflector, and a wireless receiver. The device including a first wheel having a wheel hub motor embedded therein, the motor rotatably connected to a first partial axial shaft connected to the base. The device including a second wheel having a wheel hub motor controller embedded therein, the motor controller rotatably connected to a second partial axial shaft connected to the base and operative to control a speed of rotation of the first wheel and the second wheel. The device also including a remote control for controlling the speed of rotation of the first wheel and the second wheel, the remote control operative to transmit one or more control signals to the wireless receiver, the wireless receiver being electrically coupled to the motor controller.

A roller board is a board that uses wheels, caster balls, and cleats to mimic the movement of a snowboard. The roller board includes a riding board, a front roller mechanism, and a rear roller mechanism. A user stands upon the riding board and is secured to the riding board. The front roller mechanism and the rear roller mechanism each include an inline-wheeled truck, left and right caster balls, and left and right elongated cleats. The inline-wheel truck allows the roller board to roll in a forward or rearward direction. The left and right caster balls allow a light left or right lean by the user to steer the riding board in either a left or right direction. The left and right elongated cleats allow a heavy left or right lean by the user to brake the riding board from a left or right side of the riding board.
