A low travel rear wheel suspension system for a bike includes a seat tube, left and right side flexible chainstays each with its front end attached to the seat tube, left side and right side seatstay. In the area of the seat tube where it connects to the seatstays, the seat tube is split up into a seat tube posterior part and a seat tube anterior part, the seatstays connecting to the seat tube posterior part, and the seatstays not connecting directly to the seat tube anterior part. The seat tube posterior part and the seat tube anterior part connect to one another both above and below a seat tube cavity. The seat tube posterior part and the seat tube anterior part are configured to allow flex of the seat tube posterior part towards the seat tube anterior part, and thus allow vertical flex of the flexible chainstays.

A wireless active suspension system with at least one wireless sensor coupled with at least one unsprung mass of a vehicle is disclosed. The system also includes at least one damper comprising an active valve, the damper being part of a vehicle suspension. The system additionally includes, at least one controller, the at least one controller in wireless communication with the at least one wireless sensor and the at least one damper, wherein the at least one controller receives the sensor data from the at least one wireless sensor and communicates an adjustment command to the active valve to modify a damping characteristic of the at least one damper.

A bicycle includes a front wheel, a rear wheel, a frame comprising a main frame section and an articulated frame section, the articulated frame section comprising: a lower arm rotatably supported on a first axis by the main frame section, an upper frame link, the rotatably supported on a second axis by the main frame section, an upper arm rotatably connected to the upper frame link on a third axis, an upper butt joint rotatably connected to the upper frame link and the upper arm on the third axis, and a lower butt joint rotatably connected to the main frame portion and the lower arm on the first axis, and a shock absorber having a first end rotatably supported on a fourth axis by the main frame portion and a second end connected to a fifth axis from the upper butt joint and the lower butt joint ndung is held rotatable.

The present invention is generally directed to a swing arm configuration and, more specifically, a swing arm that is supported by a shaft of a motor, such as an electric motor of a motorcycle. The configuration includes a swing arm assembly that is supported by a shaft of a motor at one end and a rear axle at the other end. Advantageously, the shaft of the motor may be a structural component of an electric motorcycle and serve as the swing arm pivot as well as the drive shaft.

A bicycle is disclosed. In certain examples, the bicycle includes a head tube coupled to a top tube and a down tube, and a seat tube coupled to the top tube and the down tube. The bicycle is coupled to a rear suspension system in certain examples. The rear suspension includes an upper linkage member pivotally coupled at a first pivot point with the bicycle frame and pivotally coupled at a second pivot point with a rear suspension system. The rear suspension also includes a lower linkage member pivotally coupled at a first pivot point with the bicycle frame and pivotally coupled at a second pivot point with the rear suspension system, and where the lower linkage member includes a bottom bracket shell.

An electric tricycle including a frame having a front end coupled to a steering assembly, the steering assembly having a front wheel, and a rear end coupled to a rear wheel assembly, the rear wheel assembly having two rear wheels. At least two pedals rotatably coupled to the rear wheel assembly and configured to move in a reciprocating motion, the at least two pedals having an engaged configuration wherein the at least two pedals are engaged with the two rear wheels and configured to rotate the two rear wheels in a first direction, and a disengaged configuration wherein each of the at least two pedals is disengaged from the two rear wheels and aligned with another of the at least two pedals. An electric motor electrically coupled to a battery and configured to engage with the two rear wheels and to rotate the two rear wheels in the first direction.

A shock absorber includes a gas spring cylinder containing a piston moveable between an extended position and a compressed position within the gas spring cylinder. A mechanical actuator is arranged whereby a bleed port is automatically closed when the gas spring is compressed to a predetermined position corresponding to a desired sag setting. In one embodiment, the position corresponds to a predetermined sag setting whereby the gas spring is partially compressed. In another embodiment, a proper sag setting is determined through the use of a processor and sensor that in one instance measure a position of shock absorber components to dictate a proper sag setting and in another instance calculate a pressure corresponding to a preferred sag setting.

A rear suspension system for bicycles comprised of a bicycle main frame, upper link, lower link, swingarm, and rotatable idler member. The rear wheel follows a primarily rearwards and upwards axle path which is determined by the specific linkage geometry. The idler member is fixed to the bicycle main frame at one precise location. This idler member is positioned in such a way as to redirect drivetrain forces to create highly stable anti-squat characteristics at the statically loaded sag point in every gear combination.
