A vehicle includes a front wheel assembly, a handle assembly, a frame assembly and a rear wheel assembly, the front wheel assembly is connected to the handle assembly, one end of the frame assembly is connected to the handle assembly, the other end of the frame assembly is connected to the rear wheel assembly, the front wheel assembly is provided with a shock-absorbing device, and/or the rear wheel assembly is provided with a shock-absorbing assembly to reduce the vibration of the vehicle.

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 system and method for a rider with an improved rider-controlled recreation vehicle. A recreational vehicle with a platform medium, for example a wide fabric strap rider platform (versus a hard surface like metal, wood or the like) supported only at the ends. Advantages may include that it provides shock absorption, more road feel, different performance characteristics, and more comfort than a traditional hard platform. The platform may also be adjusted for more or less tension for different riding surfaces and conditions and the strapping can easily be replaced with natural wear or to personalize the look with custom graphic designs.

A bike frame includes including a seat tube (10) configured to receive 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). Each seat stay (12a, 12b) has a perpendicular cross-sectional profile that is elongated in a direction parallel to the plane of symmetry. 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.

The present invention provides a transformable bicycle. The transformable bicycle including: a pair of front fork members which are connected to a front wheel, and which are arranged with the front wheel interposed therebetween; a head tube which is connected a fork support bar; a frame which is coupled to the head tube, and which is connected such that the head tube is rotatable around a bolt pin; a fastening device which is connected to the head tube; another fastening device which is installed with the fastening device and a spring interposed therebetween; a fastening device handle which allows the front fork members to be folded toward the frame in such a manner that the fastening device handle rotates the head tube connected to the fastening devices around the bolt pin by pulling the fastening devices during rotation around pins; a seat; and a rear wheel.

A platform having a suspension system may include a platform with a column or parallel columns of any cross section shape rigidly protruding from one side of the platform, a base having a pipe for each column to slide along the inside of the pipe, at least one leaf spring between the base and the platform for absorbing shocks. The relative positions of these parts are kept by sliders, slider guides and position limiters so that the platform can move only in one dimension generally parallel to the pipe. Various embodiments are disclosed for using as foot platforms in one or two-wheeled self-balancing vehicles. These embodiments are simple, compact and light modules to be adapted easily in such vehicles, without affecting the balancing and steering. Some embodiments enable users to change leaf springs and adjust damping. Embodiments of foldable platform are also disclosed.

The present disclosure relates to terrain-tracking or vehicle suspension systems that include travel at least one of the front or the rear of the vehicle. Various embodiments include a suspension above the vehicle (upper suspension). Embodiments include a suspension or travel in at least one of the upper vehicle (rear and/or front), middle vehicle (rear and/or front), or below vehicle (rear and/or front). Various embodiments included a combination thereof.

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.

A vehicle includes a front wheel assembly, a handle assembly, a frame assembly and a rear wheel assembly, the front wheel assembly is connected to the handle assembly, one end of the frame assembly is connected to the handle assembly, the other end of the frame assembly is connected to the rear wheel assembly, the front wheel assembly is provided with a shock-absorbing device, and/or the rear wheel assembly is provided with a shock-absorbing assembly to reduce the vibration of the vehicle.

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.
