An electronically controlled suspension system for a bicycle includes at least one spring element between first and second parts the bicycle, both parts being movably interconnected. At least one parameter of the spring element is modified. At least one actuator influences the spring element to modify the at least one parameter. An electronic module produces a control signal for the at least one actuator. A control device is influenced by the control signal produced by the electronic module. The control device is connected to at least one of the electronic module and the actuator through a radio signal. A corresponding method controls the suspension system for the bicycle and a computer program executes the method.

A rear swing arm structure for an electric scooter includes a pedal rear portion, a telescopic shock-absorbing unit, two swing arm units, and connecting rods. The swing arm unit is pivotally connected to the pedal rear portion, with the first connecting rod linking the telescopic shock absorber and the second connecting rod connecting the swing arm unit and the first rod. When the rear wheel encounters vibration, the swing distance of the first connecting rod adjusts to match the rear wheel's movement. This automatic adjustment balances shock absorption and buffering, preventing the system from being too hard or soft. This design improves comfort, reduces tail swinging and slipping, and enhances grip during turns, resulting in smoother control and increased safety on various road surfaces.

A control device includes a reference unit, a correction unit, and a target setting unit. The correction unit sets a reference correction current serving as a reference in determining the correction current to 0 in an extremely low velocity range of a change velocity of a stroke amount, sets the reference correction current to a predetermined steady-state value in a medium and high velocity range of the change velocity, and sets the reference correction current to a value equal to or larger than 0 and equal to or smaller than the steady-state value in a low velocity range of the change velocity.

Transportation vehicles, suspension systems and related methods are provided herein. A three wheeled vehicle can include a frame having first and second sides and front and rear ends and a steerable front wheel secured to the front end of the frame. The vehicle can also include a first trailing wheel arm with a first rear wheel and a second trailing wheel arm with a second rear wheel. The vehicle can include a horizontal linkage having first and second ends and a midsection therebetween. The horizontal linkage can be pivotably connected to a pintle on the frame at the midsection with the horizontal linkage linked to an underside of the first trailing wheel arm between the first wheel and the central suspension joint and linked to an underside of the second trailing wheel arm between the second wheel and the central suspension joint.

A bicycle shock absorber and methods for differentiating between rider-induced forces and terrain-induced forces includes a first fluid chamber having fluid contained therein, a piston for compressing the fluid within the fluid chamber, a second fluid chamber coupled to the first fluid chamber by a fluid communication hose, and an inertial valve disposed within the second fluid chamber. The inertial valve opens in response to terrain-induced forces and provides communication of fluid compressed by the piston from the first fluid chamber to the second fluid chamber. The inertial valve does not open in response to rider-induced forces.

A traveling vehicle includes: a vehicle body frame, a pair of right and left front crawler traveling devices, a pair of right and left rear crawler traveling devices, a front suspension device that suspends the pair of right and left front crawler traveling devices on the vehicle body frame, and a rear suspension device that suspends the pair of right and left rear crawler traveling devices on the vehicle body frame. The front suspension device integrally suspends the pair of right and left front crawler traveling devices on the vehicle body frame and allows the pair of right and left front crawler traveling devices to be swingable in the vertical direction with respect to the vehicle body frame.

A brake caliper arrangement structure for a saddled vehicle, wherein a brake caliper for braking and a brake caliper for parking are provided on a swing arm. At least one or other of the brake caliper for braking and the brake caliper for parking is arranged in front of a rear axle being the axle of the rear wheel, when viewed from a side, at a position on a vehicle widthwise inside of the swing arm and overlapping the swing arm.
