A folding mechanism for a scooter to transition the scooter from a use position to a folded position. The folding mechanism has an upper housing connected to a steering tube of the scooter, and a lower housing operably secured to a fork of the scooter and pivotally secured to the upper housing about a folding axle. A lever is pivotally attached to the folding axle and operates to move a locking clamp from an unlocked position to a locked position. The locking connects the upper housing and the lower housing in the locked position. Additionally, a locking sleeve engages the lever to prevent the lever from being moved from the locked position to the unlocked position when the locking sleeve is in its locked position.

A vehicle includes an engine, at least three wheels including a front wheel and a rear wheel, a fuel tank above the engine, a seat rearward of the fuel tank, a canister positioned lower than the fuel tank, and a vent hose to supply air therethrough into the canister to desorb the adsorbed fuel evaporative emission from the canister. An upstream end of the drain hose is connected to the vent hose. A downstream end of the drain hose is positioned lower than the canister.

A steering stop for bicycle handlebars includes a first stop element. The stop element can be connected to a steer tube of a bicycle fork in particular in a clamping manner and includes two stops. A second stop element can be fixed on the bicycle frame and cooperates with the first stop element. For passing lines therethrough, which originate for example at a brake and/or gearshift unit, the first stop element includes at least one recess.

An embodiment of the present disclosure may provide a drift scooter, including: handlebars operatively coupled to a front wheel and mounted from a scooter body; first and second legs extending from the scooter body; first and second castered rear wheels mounted from the respective first and second legs; and first and second foot platforms operatively coupled with the respective first and second castered rear wheels wherein the first and second foot platforms pivot. The first and second rear wheels are adjusted in response to pivoting of the respective first and second foot platforms.

A pump-action mobility and exercise device may include a pumping arm attached to a foot slide. As the pumping arm is actuated, the foot slide moves forward and rearward in response to the pumping action. The foot slide can also be moved by a user's foot movement. The foot slide may be connected to a drive mechanism that selectively engages a chain or belt that loops around a drive wheel arranged on an axle of the vehicle. When the drive mechanism catches and moves the belt or chain in a forward direction, the axle rotates in a forward direction to drive the vehicle forward. A reverse mechanism may also be provided that selectively causes the drive mechanism to catch and drive the belt or chain in an opposite direction.

The invention proceeds from a steering device for two- and three-wheeled vehicles, which ensures a rotationally fixed connection between handlebars and a handlebar stem and/or between a handlebar stem and a fork of the two- or three-wheeled vehicle, and a steering device for two- and three-wheeled vehicles having a stop. The steering device has a frame with a head tube (1), a fork (2) with a stem tube (3) and a handlebar stem (4) with handlebars (7). In addition, a stop can be provided for the handlebars (7), which consists of a base (12), which is connected in a rotationally fixed manner to the fork (2) of the two- or three-wheeled vehicle, with a recess (14) and a stop element (15), which is securely arranged in the bearing shell (11) and protrudes radially into the recess (14).

According to the invention, in each case one component of the rotationally fixed connection has a smooth cylindrical surface over its axial length, whilst the surface, which is in frictional operative connection with this smooth cylindrical surface in the mounted state, of the other component, which is arranged coaxially to that first-mentioned, is constructed as an n-sided polygon.

A vehicle including a single front wheel arranged on a center line extending in a front-rear direction, two rear wheels arranged on a left side and a right side of the center line, a steering part arranged above the front wheel, a placement part on which feet of an occupant are placed, a first member rotatably supporting the front wheel and supporting the front wheelin a steerable manner by the steering part, a second member arranged behind the first member to rotatably support the two rear wheels, and a connecting part connecting the first member and the second member swingably in a left-right direction about an axial line extending in the front-rear direction. The placement part is supported by the second member (20).

A bicycle handlebar assembly comprises a base bar, a v-shaped stem selectively removable from the base bar, and a bicycle fork assembly. Control cables from the bicycle may be routed from the base bar into hollow diverging stem members of the v-shaped stem. The bicycle fork assembly comprises an external-steerer fork having a load-bearing member and a preload tensioning rod. The preload tensioning rod fits within a head tube of the bicycle, and a hollow space around the preload tensioning rod accommodates control cables passing from the v-shaped stem into a hollow portion of the bicycle frame. The v-shaped stem is secured against the base bar by a pair of nut plates. In some examples, an engagement portion of an accessory such as an aerobar extension assembly is configured to secure the v-shaped stem and an aerobar extension against the base bar.
