Embodiments of the present disclosure include a wireless remote control or remote control application for controlling the lighting of an electronic personal transportation vehicle. Embodiments can solve problems related to sharing electronic personal transportation vehicles by uniquely identifying a user, and allowing that user to control the lighting of the electronic personal transportation vehicle. In this manner, other users can control the lighting at different times, depending on the specific person that is using the electronic personal transportation vehicle at any given time.

This technical solution relates to the field of Personal Mobility Devices (PMD) equipped with a Wheel Lighting System. A personal mobility device (PMD) containing wheels made of a substance containing photoluminophore, a wheel lighting system that contains at least one source of UV-light connected to a battery, a controlling device which activates the source of UV-light, wherein at least one source of UV-light is installed in such a way that enables the illumination of at least a part of the wheel.

A portable energy-saving and environment-friendly electric vehicle is light in weight, small in volume, convenient in electricity charging, and can be disassembled for portability in a backpack. The backpack is further furnished with a crank-handle generator to enable manpower electricity generation and working out simultaneously. This energy-saving and environment-friendly electric vehicle is mainly comprised of two adjustable skateboards and a support rod for adjusting speed and connecting a battery set. The battery set can be conveniently replaced roadside or at other locations. In a situation of power loss, manpower can be used to charge the battery set. Thus, the situation of power loss fully disabling the electric vehicle can be met. In addition, the battery set associated with the generator is reliable for charging mobile phones and computers.

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 caster board can include a front platform, a rear platform, and at least two neck sections extending between the front platform and the rear platform. The neck sections can serve as a torsion element allowing twisting of the front platform relative to the rear platform. An aperture between the neck sections can be configured to receive an insert. The insert can alter a structural characteristic of the caster board, such as the torsional stiffness of the caster board.

An apparatus for illuminating a rotating element of the apparatus with as few as a single light source and a method for assembling such apparatus are disclosed herein. The apparatus comprises a center, a clear substrate element that may rotate about the center, and a light source for evenly illuminating the clear substrate element. The light source is configured to emit light toward the clear substrate element at an angle, which is predetermined based on one or more attributes of the clear substrate element, such as the geometry and the index of refraction.

A marking device that is supported by a personal mobility vehicle, such as a scooter, is movable from a first position, in which the marking device does not contact the riding surface, and a second position, in which the marking device contacts the riding surface. The marking device includes an attachment portion and a marking portion that creates markings on the riding surface as a result of frictional contact with the riding surface. The marking device can also include an actuation portion which is accessible to the user and allows the user to move the marking device to the second position. In one arrangement, the marking device includes an elastic marking member which is configured to bend in order to maintain contact with the riding surface.
