A rugged and compact articulated wheel with at least two hubs, and wheeled vehicles that include one or more of such articulated wheels.

The invention relates to a device for energy recovery in bicycles with a mid-mounted motor drive unit and at least one rear wheel, comprising a first component that is connected to an element of the rear wheel hub or the rear wheel, such that a rotation of the rear wheel is transmitted to the first component, regardless of the direction of rotation, an energy-transmission device interacting with the first component, a recuperation element that interacts with the energy-transmission device, and a generator that interacts with the recuperation element to recover the rotational energy of the rotational movement of the rear wheel.

A freehub of a bicycle contains: a body fitted and rotating on a rotary shaft. A receiving sleeve is connected with the body and fitted on the rotary shaft, and the receiving sleeve includes an accommodation holder configured to accommodate a freewheel. A ratchet assembly is mounted between the body and the receiving sleeve, the ratchet assembly includes multiple chutes, and a central axis of a respective chute is not parallel to a central axis of the rotary shaft. A toothed ring is fitted between the fixing element and the body. The ratchet assembly includes multiple teeth, multiple engagement elements, and multiple resilient elements. A respective resilient element abuts against the respective chute and a respective engagement element, such that the respective engagement element is urged by the respective resilient element to linearly move toward the respective tooth so as to engage with the respective tooth.

A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.

An intelligent automatic processing apparatus for spoke holes of bicycle rims is revealed. The apparatus includes a seat pivotally connected to a machine body and provided with a rotary base. A rim is clamped and fixed by clamping jaws on the rotary base and a control unit drives an incline unit to incline the seat connected at an angle desired for control of slopes of holes being drilled. The control unit also drives a rotary indexing power source to rotate the rotary base at different angles according to the numbers and positions of spoke holes desired. Thus a drilling assembly drills the spoke holes on the rim. Thereby the spoke holes with various angles can be drilled on different positions of the rim by the control unit which adjusts positions and inclination angles of the rim accurately. Therefore, the drilling of the spoke holes is more convenient.

An eccentric wheel adjustment device includes a hub (1), an adjustment disk (2) and a release structure (3). The hub (1) has an axle portion (10) eccentrically arranged and an inner ring portion (11) formed around the axle portion (10). The adjustment disk (2) has a disk seat (20) for the hub (1) being pivotally disposed thereon and a positioning member (21) for positioning the hub (1) on the disk seat (20). The positioning member (21) has an outer ring portion (210) for aligning the inner ring portion (11) of the hub (1) in the outer ring portion (210). The release structure (3) includes a limiting block (30) and a switch member (31) driving the limiting block (30) to act so as to drive the limiting block (30) to straddle between the hub (1) and the adjustment disk (2) or to move back to the inner ring portion (11).

A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim, a first sidewall, and a second sidewall spaced apart form the first sidewall. The first sidewall and the second sidewall extend radially outward from the radially inner portion. The radially inner portion includes a stack of strips of material. The stack of strips includes a plurality of strips and a hole through the plurality of strips. The plurality of strips are nonparallel to each other. The plurality of strips are positioned about the hole through the plurality of strips.

A driving mechanism of a bicycle free-coaster hub includes a driving assembly, a clutch assembly, an epicyclic gear assembly, a resisting member, and forward drag and reverse drag members. The clutch assembly includes an output clutch unit disposed inner the hub and an input clutch unit disposed with the driving assembly to form a clutching or engaging state with the output clutch unit. The epicyclic gear assembly includes a sun gear coupled with the input clutch unit, a ring gear mounted on the hub, a planet gear carrier having a plurality of planet gears engaged with the ring gear and the gear portion of the sun gear. The resisting member is disposed between the sun gear and the hub axle. The forward drag member is disposed between the ring gear and the sun gear. The reverse drag member is disposed between the planet gear carrier and the hub axel.

A rim assembly for a bicycle wheel includes a rim, a first protruding tire retaining feature attached to a first surface of the rim, and a second protruding tire retaining feature attached to a second surface of the rim. The first surface is a surface of a first tire retaining wall of a radially outer tire engaging portion of the rim, and the second surface is a surface of a second tire retaining wall of the radially outer tire engaging portion. The second surface faces the first surface. The first protruding tire retaining feature and the second protruding tire retaining feature are made of a first material, and the first tire retaining wall and the second tire retaining wall are made of a second material. The second material is different than the first material.

A valve stem support apparatus for supporting a valve stem while attached to a pump includes a bracket having a bracket top side, a bracket right side and a bracket left side. The bracket top side has a valve aperture extending therethrough. The valve aperture slidingly receives a valve stem of a tire of a bicycle. Each of the bracket left side and the bracket right side has a screw aperture extending therethrough. A receiving distance between the bracket right side and the bracket left side is wider than a rim of the bicycle. A pair of thumb screws is coupled to the bracket. The pair of thumb screws is threadingly engaged with the screw apertures of the bracket left side and the bracket right side to engage the rim of the bicycle and secure the bracket.
