A wheel for a bicycle, or other human powerable vehicle, has a hub that includes: (a) an axle for attachment to a bicycle frame; (b) a set of bearings that connect the axle to a rotating sleeve; and (c) at least three connection points fixedly connected to the rotating sleeve. The connection points are used to detachably attach an annular module to the hub using attachment elements that each comprise conical frustum surfaces. The attachment elements are configured to axially press a portion of the hub to a portion of the annular module, as well as radially aligning the hub to the annular module. The annular module also has a set of spoke attachment points configured for tensioned spokes that connect the annular module to a wheel rim. The spoke attachment points are in a circular configuration on two parallel offset planes that are perpendicular to the axis of rotation of the rim.

An air deflector that is at least partially disposable within a tubeless tire of a bicycle wheel includes a body. The body includes at least one wall defining an air input end and an air output end of the body. The body is attachable to a valve of the tubeless tire at the air input end, such that when air is introduced into the body via the valve, at least some of the air is deflectable by one or more walls of the at least one wall out of the body at the air output end.

A wheel is assembled and fitted with a frame of the scooter, and includes a bearing support, a hub, at least one bearing and a hollow area. The bearing support includes an inner surface facing towards a rotation center of the wheel. Each bearing includes an outer ring and an inner ring, the outer ring is fixedly connected to the hub, and the inner ring and the frame are fixedly connected to the bearing support, respectively. The hollow area is surrounded by the inner surface.

A non-pneumatic tire includes an inner cylinder (6) that is attachable to an axle (15a), an outer cylinder (4) that surrounds the inner cylinder from the outside in the radial direction of the tire, and an elastically deformable connection member (3) that connects the inner cylinder and the outer cylinder to each other. A light-emitting part or a reflecting part that reflects light is provided in at least one portion of the inner cylinder, the outer cylinder, and the connection member.

The present invention provides a non-pneumatic tire including an inner tube (6) attachable to an axle (15a), an outer tube (4) configured to surround the inner tube from an outer side in a tire radial direction, and an elastically deformable connecting member (3) configured to connect the inner tube and the outer tube to each other, the non-pneumatic tire including at least one of a detection section configured to detect occurrences of scratching, damage, or deterioration in the non-pneumatic tire; and a reporting section (33) configured to report occurrences of scratching, damage, or deterioration in the non-pneumatic tire.

A wheel for a vehicle is provided. The wheel has a first rim support member having a first hub portion rotatably mounted on an axle, and a second rim support member having a second hub portion releasably rotatably mounted on the axle, the second rim support member being releasably secured to the first rim support member along a region spaced from the axle. A rim portion extends from at least one of the first rim support member and the second rim support member and is configured to support a tyre thereon. A flywheel is positioned between the first rim support member and the second rim support member and has a flywheel hub portion releasably rotatably mounted on the axle between the first hub portion and the second hub portion.

A wheel for a human-powered vehicle is provided. The wheel has a flywheel rotatable about a flywheel rotation axis. A flywheel drive is positioned to engage the flywheel to control rotation thereof. A control unit is coupled to the flywheel drive and configured to determine a target rotation speed for the flywheel based at least partially on user input received via an electronic user interface and motion data received from at least one sensor, and direct the flywheel drive to rotate the flywheel at the target rotation speed.

A disc brake device and a bicycle. The disc brake device comprises a bicycle frame, a mounting shaft, a wheel, and a brake disc; fork pieces is fixedly connected to a frame body; the mounting shaft is fixedly connected to the fork pieces; a hub is movably connected to the mounting shaft; spokes are provided between the hub and a rim; the brake disc is fixedly connected to the hub; the brake disc and the wheel can rotate together with respect to the mounting shaft; the brake disc has an inner surface disposed facing the spokes and an outer surface disposed facing a fork piece; a first distance, in the axial direction of the mounting shaft, between the edge of the inner surface of the brake disc farthest from the hub in the radial direction of the mounting shaft and each spoke is less than or equal to 10 mm.

Kart tracks are provided that can include a magnetic support material below a polymeric coating. Karts are provided that can include processing circuitry operatively coupled to at least one motion sensor and at least one kart control assembly. Methods for controlling passenger operated amusement karts are also provided. Karts are also provided that can include at least one lateral interchangeable battery assembly. Methods for providing power to a passenger operated amusement kart are also provided. Karts are also provided that can include an articulating chassis. Methods for traversing passenger operated amusement kart tracks are also provided. Kart wheel assemblies are also provided. Methods for engaging a passenger operated amusement kart to a track are provided.
