The vibration isolator can be operatively positioned with respect to the bicycle saddle. The vibration isolator being configured to exhibit a non-linear stiffness profile. The non-linear stiffness profile can include a region of quasi-zero stiffness. The vibration isolator including a plurality of spring members arranged in a stack.

A rear wheel suspension system for a bike, includes a seat tube, left and right side flexible chainstays, left and right side seatstays. A leaf spring interconnects the seatstays and the seat tube, wherein one end of the leaf spring is connected to the upper end area of said seatstays, the leaf spring extending upwardly from its point of connection to the upper end area of the seatstays to a point of connection to the seat tube of said bicycle. The leaf spring is arranged at a distance D to the seat tube in a direction perpendicular to top and bottom surfaces of the leaf spring to allow flex of the leaf spring towards the seat tube and thus vertical flex of said flexible chainstays.

A brake caliper for a bicycle includes a housing configured to be installed on the bicycle, the bicycle including a disc attached to a wheel of the bicycle. A brake pad is installed within the housing and is configured to move between a braking position and a non-braking position. The braking position is a location within the housing where the brake pad contacts the disc when the housing is installed on the bicycle. The non-braking position is a location within the housing where the brake pad is further from the disc than in the braking position. The caliper also includes a biasing member configured to bias the brake pad in a downstream direction within the housing with the brake pad is in the non-braking position, the downstream direction being parallel to a direction of rotation of the disc when a wheel of the bicycle is rotating to move the bicycle forward.

A wheel suspension system, comprising, a wheel rim, a plurality of adaptors equidistantly mounted on inner periphery of the wheel rim, a plurality of suspension curved elastic members having drafted ends configured to be circumferentially and linearly disposed into the adaptor along the wheel rim, and a multi-layered hub having a plurality of interlocked holders away from its centre towards the wheel rim for interlocking the elastic members at the centre. The wheel suspension system is cost effective for both users and manufacturers, user friendly, comfortable, easy to assemble or disassemble, comfortable and provides safety in cases of accidents.

The present disclosure provides a scooter including a wiring structure. The wiring structure is fixedly connected to the handle assembly, the frame assembly, and the front wheel assembly, respectively. The second tubular member sleeves a periphery of the first tubular member and an axis of the first tubular member coincides with an axis of the second tubular member. A first opening and a second opening are respectively provided on the first tubular member and the second tubular member, and the first opening is opposite to the second opening. One end of the third tubular member is fixedly connected to the second tubular member along the second opening. When the first tubular member is rotated relative to the second tubular member there is a gap. The scooter of the present disclosure has the advantage of smoothly guiding the wires without damaging the wires.

A bike frame includes including a seat tube (10) for receiving a seatpost (2), a front portion comprising a top tube (13) connecting the seat tube (10) to a head tube (16), the seat tube (10), the top tube (13). The head tube (16) extends in a plane of symmetry of the bike frame (1). A rear portion has two chain stays (11a, 11b) and two seat stays (12a, 12b) arranged symmetrically relative to the plane of symmetry of the bike frame (1). The two seat stays (12a, 12b) are independent of each other and the two seat stays (12a, 12b) have a preform that is curved along at least one arc in a plane passing through the two seat stays, so as to enable the two seat stays to move away from or closer to each other under the action of a vertical load.

A cycle crank assembly includes a crank spindle and a drivetrain connector configured to translate rotation of the crank spindle into rotation of a wheel. A crank arm includes a pedal interface configured to receive a pedal spindle of a cycle pedal. A slip connection is configured to allow the crank arm to rotate about the crank spindle. A resiliently deformable member is connected to the crank spindle and the crank arm proximate to the pedal interface. The resiliently deformable member translates rotation of the crank arm into rotation of the crank spindle. The resiliently deformable member deforms under load to store pedal energy provided by a rider to the cycle pedal and returns at least a portion of the pedal energy when not under load in a direction of the rotation.

A structural element of a cycle includes at least one tubular sheath provided with an outer wall delimiting, with an inner partition, at least one cavity in which a vibration damping system is accommodated. The sheath includes at least two internal cavities, each delimited between the inner partition and the outer wall, one of the internal cavities forming a housing in which the damping system is accommodated and attached.

A vehicle wheel suspension system includes two relatively movable portions and a resilient blade that includes two means for mechanical connection to both relatively movable portions, respectively. The blade has a flexural resilience at least 100 times greater than the tensile resilience, and is resiliently deformable between: a resting state in which the blade has an inwardly curved profile, and a maximally extended state in which the blade has an elongate profile, the length of which corresponds to that of the neutral fiber of the blade, while passing through intermediate extension states in which the blade has profiles that are less and less inwardly curved. The suspension system is deformable between an initial state in which the relatively movable portions are in a close configuration, and a compressed state in which the relatively movable portions are in a separated configuration and bias the blade.
