The present disclosure relates to the location of a disc brake caliper mounted to a trailing-link suspension fork. In one aspect, the disc brake caliper is attached to a sprung portion of the fork, hence adding zero mass and corresponding inertia to the un-sprung portion of the suspension system. Further, the disc brake caliper is positioned forward of the wheel axle and linkage member.

In an embodiment, there is provided a motorcycle comprising at least one front wheel, at least one rear wheel and a vehicle body, the vehicle body comprising a substantially open elongate duct extending longitudinally through a central portion of the vehicle body between an open inlet aperture arranged at a front portion of the vehicle body and an open outlet aperture arranged at a rear portion of the vehicle body.

A multi-bar suspension assembly for a cycle having improved stability includes a first arm having a first arm fixed pivot and a first arm shock pivot. The first arm includes a hollow internal portion having first end and a second end that are both wider than a narrow intermediate portion. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a first shock mount and a second shock mount. A wheel carrier has a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another, and a wheel mount that is adapted to be connected to a wheel. A control link has a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot.

A suspension assembly for a cycle includes a plurality of links pivotably connected to one another by a plurality of pivots. A rotation sensor measures an angular relationship between two links and a setpoint of the suspension assembly is adjusted based on the angular measurements.

A foldable electric scooter and a manufacture method of the same. The foldable electric scooter includes a main body assembly, a front fork assembly located at the front end of the main body assembly, a rear fork assembly located at the rear end of the main body assembly, a telescoping plate assembly located on top of the front fork assembly and a handlebar assembly located on top of the telescoping plate assembly. The foldable electric scooter has a double headset design that increases a rake angle for more steering stability while still keeping the steering upright for an upright holding of the handlebars. The foldable electric scooter is manufactured by stamping of flat plate material.

Front forks for bicycles are described herein. An example front fork includes an upper fork including a first leg and a second leg, a lower fork including a third leg disposed along the first leg and a fourth leg disposed along the second leg, a first set of links rotatably coupled between the first leg and the third leg, and a second set of links rotatably coupled between the second leg and the fourth leg. The first and second sets of links enable the lower fork to swing relative to the upper fork. The front fork also includes a steerer tube coupled to the front fork and a spring in the steerer tube. The spring is configured to bias the lower fork away from the steer tube.

A vehicle includes a front differential, a pair of constant-velocity joints, and a steering mechanism. The steering mechanism includes a pitman arm, a pair of tie rods, a pair of first link arms each connecting the pitman arm with a corresponding one of the pair of tie rods, and a pair of second link arms each connecting a corresponding one of the pair of first link arms with a body frame. In a plan view, at least a portion of each constant-velocity joint is located between first and second straight lines extending in a fore-aft direction and through first and second connectors extending between the tie rods and the first link arms. The first connector, the second connector, and at least a portion of each constant-velocity joint are located between third and fourth straight lines extending between the first and second link arms.
