A shock absorber includes a spring bearing that supports one end of the suspension spring which biases the shock absorber main body in an extension direction; a jack configured to change an axial position of the spring bearing; a ring-shaped adapter freely fitted to an outer periphery of the spring bearing; a restricting portion disposed between the spring bearing and the adapter, the restricting portion restricting a movement of the adapter in an axial direction with respect to the spring bearing; a rotation stop member mounted on the shock absorber main body to stop a rotation of the adapter; and a stroke sensor disposed between the adapter and the rotation stop member.

A tube-type electric driving device is provided. The tube-type electric driving device includes a support shaft tube, a motor, a reducer, a one-way clutch bearing, an input gear shaft, a shaft frame, a pedal shaft, a fixing assembly, a power steering component, and a Hall sensor. The motor is fixed in the support shaft tube. The reducer is disposed on the driving shaft of the motor. An inner ring of the one-way clutch bearing is mounted on the output shaft of the reducer, and an outer ring of the one-way clutch bearing is fixed in a fixing hole of an input gear shaft. The shaft frame is connected to the support shaft tube. The pedal shaft is rotatably inserted in the shaft frame. The fixing assembly and the power steering component can be disposed on the pedal shaft, and a Hall sensor is connected to the motor.

A stationary jumping and trick bike is disclosed. An example device includes a frame assembly having a handlebar on a forward portion of the frame assembly and a seat on the frame assembly. A leg member including a leaf spring is connected to the frame assembly by a bracket having a plurality of ports selectable for pivotably attaching the leg member to the frame assembly to adjust pitch and/or angle of attachment of the leg member. A plurality of tensioners are connected between the leg member and the frame assembly. A foot rest is provided on the frame assembly. A standing and/or seated user holding the handlebar on the frame assembly can practice jumps and tricks by lifting and landing a lower portion of the leg member on a solid surface.

A flow path control device according to one embodiment includes a first valve which transitions between a closed state where a first flow is closed and an open state where the first flow path is open by moving toward an space from the closed state. The first valve is formed with an axial through-hole that communicates with the first flow path and the space. A pressure-receiving area of the first valve against a jack chamber is smaller than that against the space. Further, a second valve is provided in the space on a second flow path so as to transition between a first state where the axial through-hole is closed and an inflow path oriented toward the space from the jack chamber is open and a second state where it is closed and the axial through-hole is open.

A bicycle folding mechanism includes a frame, a stem, and a front fork. The frame includes a front tube at an end thereof. The stem is inserted into the front tube. The stem is connected and pivotal relative to the frame. The stem has an end, which is adjacent to the frame, connected with a connecting seat. The front fork includes at least one connecting end and at least one front end on opposite ends. The at least one connecting end is connected and pivotal relative to the connecting seat such that the front fork is pivotal relative to the connecting seat. The front fork is pivotal between a deployed position in which the at least one front end is positioned away from the frame and a folded position in which the at least one front end is positioned adjacent to the frame.

Telescopic suspension device (10) attached to the hub (422) of a wheel (424) of the type comprising a first tube (12), a second tube (14) sliding relative to the first tube and a main spring (34) arranged inside said tubes, and further comprising a pretension adjustment stopper (18) of the spring (34) installed at the upper end (16) of said first tube. The suspension device comprises a pretension tracking system (39) of the spring, representative of the weight of the user, connected to the stopper (18).

A wheel mounting member having a damping structure may include a dropout in which an axle insertion groove is formed at one side of a lower portion thereof, wherein a guide slot may be formed in a predetermined direction at a predetermined distance from the axle insertion groove; a bracket in which a protrusion inserted into the guide slot is formed at a lateral surface thereof; and an elastic member that is inserted into the guide slot and elastically supports the protrusion, wherein the elastic member may absorb impact transmitted to the dropout.

The present disclosure relates to a damping cartridge system configured to be arranged in a leg of a vehicle front fork, the damping cartridge system comprising: an inner cartridge tube configured to be coupled to a first part of the vehicle front fork leg, a piston head coupled to a second part of the vehicle front fork leg configured to be moveable relative the first part of the front fork leg, the piston head configured to be moveable inside the inner cartridge tube between a first position and a second position, an outer cartridge tube sized and adapted to at least partly house the inner cartridge tube, the outer cartridge tube comprises a plurality of ridges and grooves arranged side-by-side along the axial direction of the outer cartridge tube, thereby forming a corrugated portion for distributing radial forces acting on the damping cartridge system.

Example bicycle suspension components are described herein. An example suspension component includes a first tube and a second tube configured in a telescopic arrangement and defining an interior space, and a damper in the interior space. The damper includes a damper body defining a chamber, a damper member in the chamber, and a shaft coupled to the damper member. The example suspension component also includes an isolator coupling the shaft to a bottom end of the second tube, the isolator including an elastomeric member to absorb vibrations.

A bicycle may include a front triangle and a rear suspension system that couples the front triangle to a rear wheel and is dampened by at least one shock absorber. The rear suspension system includes a six-bar linkage having two ternary links separated from each other by one or more binary links, such that the two ternary links do not share a common joint. One of the ternary links may comprise a chain stay. In some examples, the other ternary link may comprise the front triangle. In some examples, the other ternary link may comprise a rocker arm coupling a seat stay link to the shock absorber.
