A powered two-wheel vehicle includes a chassis extending between a rotatable front fork and a fixed rear fork. A deck is attached to the chassis to enclose a compartment. A front wheel is rotatably attached to the front fork and a rear wheel is rotatably attached to the rear fork via a hub motor. The steering assembly includes a head tube supported above and in front of the deck by a pair of arched frame tubes, a steering tube rotatably connected to the head tube, and a rotational damper connected between the head tube and the steering tube.

A wheeled board device with forward and rearward in-line wheel structures attached to a user platform. The forward wheel may have a forward tilt axle or be otherwise direction-biased to permit lean-based turning. The rear wheel may be singular or comprise two tires or the like and be motorized or not. The wheels are preferably large to more readily handle surface irregularities. A self-balancing wheelie mode is disclosed in one embodiment. Other embodiments include placement of the forward tilt axle within or without the envelope of the front wheel. The user platform is below the top of the rear wheel and preferably near the axis of the rear wheel, among other features.

An electric skateboard (100), belonging to the field of transportation means, comprises a remote control (101), a board body (102), a front wheel (103), a rear wheel (104), and a battery built in the board body (102), wherein the front wheel (103) and the rear wheel (104) are respectively rotationally provided at two ends of the board body (102), a hub motor for driving the rear wheel (104) is provided inside the rear wheel (104), the hub motor is connected with the battery, and the hub motor is further wirelessly connected with the remote control (101). The electric skateboard (100) controls the operation of the skateboard by a wireless remote control (101), omitting a pressure sensor and a mounting groove, and it has a simple structure, a low manufacturing cost, strong reliability, and strong integrity, and can resist water.

A motorized skateboard comprising a board and a plurality of wheels attached with the board is presented. At least one of the wheels includes an electric motor contained within the wheel to propel the skateboard when activated. In one case, the motorized skateboard comprises two wheels and where the wheels are pivotally attached with the board to assist in board turning. The wheels may also be shaped so that they are convex to assist in board turning. There may also be a tread disposed over and between the wheels such that the tread moves as the wheels rotate.

In an aspect, a tire for use with a single wheel, self-balancing vehicle is provided. The tire has a tire body with a tread configured for engagement with a ground surface. The tread has a lateral profile having a central region, a first lateral region tapering towards a first lateral side of the tire, and a second lateral region tapering towards a second lateral side of the tire. The lateral profile is substantially free of discontinuity. The tread has a non-directional tread groove arrangement that is asymmetrical about a central circumference line of the tire. The tire has a hardness selected to substantially prevent deformation of the first profile and the second profile during riding by a rider.

An electric vehicle includes a carrier, a free-wheel unit, a foot-wheel unit, a driving unit, a first angle-detecting unit and a micro processing unit. The carrier is for supporting a user. The free-wheel unit is disposed at one end of the carrier. The foot-wheel unit is disposed at the other end of the carrier. The driving unit is disposed at the free-wheel unit or the foot-wheel unit, and is for providing a power to the electric vehicle. The first angle-detecting unit is disposed at the free-wheel unit or the carrier, and is for detecting a swinging status between the free-wheel unit and the carrier so as to provide a swinging signal. The micro processing unit is signally connected to the driving unit and the first angle-detecting unit. When the swinging signal achieves a predetermined condition determined by the micro processing unit, the driving unit is turned on.

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.

An adjustable wheel mobility vehicle can have a support structure for supporting a rider, a modular conveying feature with a wheel, and an attachment that physically and tightly secures the modular conveying feature to the support structure in at least two different positions. A tool-free mechanism can allow a user to free the modular conveying feature from the support structure for movement to another position. A system for adjusting a skateboard wheel position can include a wheel support structure having multiple wheel attachment positions, and a wheel assembly comprising a skateboard wheel and a base. The wheel can swivel with respect to the base and the base can join to the wheel support structure. The base and wheel support structure can tightly join to prevent rotation of the base with respect to the wheel support structure and that tightly retain the base in a first attachment position. A release feature can allow a user to easily loosen the base and reposition it in a second attachment position.

A platform that does not have any trucks coupled thereto and configured for a rider to ride thereon; a mount coupled to the platform, wherein the mount is configured to freely rotate 360 degrees about a first axis relative to the platform; a motor coupled to the mount and configured to operate at a rotational speed; a roller coupled to the motor such that the motor can drive the roller about a second axis distinct from the first axis relative to the platform; a power source coupled to the platform and powering the motor; a controller powered by the power source; and an IMU coupled to the platform or the mount and powered by the power source, wherein the IMU obtains a reading while the roller is rolling as the rider rides on the platform and sends the reading to the controller such that the controller adjusts the rotational speed.

A mobilized cooler device comprising a fork hanger assembly is disclosed herein. Cooler devices according to the present disclosure can comprise a platform, an attached cooler body and fork hangers connecting cog-hub assemblies to the platform. Fork hangers can be positioned such that a portion of a first fork hanger adjacent to a first end of the platform is attached to a first end of a cog-hub assembly and a second portion of the first fork hanger adjacent to a second end of the platform that is opposite the first end of the platform is attached to a second end of the cog-hub assembly. Additional fork hangers can be similarly configured. The cooler device can further incorporate additional features, including a treading positioned between the fork hangers and at least partially surrounding the cog-hub assemblies, various cog-hub assemblies and shapes, and motors incorporated into the cog-hub assemblies.
