A support frame assembly mounted to a narrow track vehicle to enhance stability during turns is provided. The support frame assembly includes a pivot frame assembly coupled to the narrow track vehicle and having a horizontal beam connected to a vertical beam, the horizontal beam supporting the seat of the narrow track vehicle thereon, a fixed frame assembly coupled to the narrow track vehicle and having a horizontal beam pivotably mounted to the vertical beam of the pivot frame assembly, and a pair of struts coupled to the pivot frame assembly and fixed frame assembly. The pair of struts apply counteracting forces on the vertical beam of the pivot frame assembly in response to pivotal movement of the pivot frame assembly relative to the fixed frame assembly.

The present disclosure provides systems, methods, and devices for operating a vehicle, such as a self-balancing vehicle, using a steering member and/or a braking member. A resistance to movement of the steering member may be controllable based upon an operating state or change thereof of the vehicle. The braking member may control a resistance to motion of at least one of at least two wheels of the vehicle based upon an operating state or change thereof of the vehicle.

Methods of teaching and learning bicycle riding skills are disclosed, including training a student to ride a bicycle comprising positioning a student on a bicycle at the top of an inclined surface with a slope in a range of 8 to 15 degrees and a distance of at least 30 feet, wherein the student straddles the bicycle's seat such that the student's feet engage the inclined surface and the student's hands engage the bicycle's hand brakes. The student releases the brakes and lifts his/her feet from the inclined surface. Under angular momentum, the bicycle moves down the inclined surface while the student steers the bicycle. The bicycle is returned to the top of the inclined surface and the steps are repeated. The student also learns to pedal the bicycle using the inclined surface with similar repeatable steps. Other skills such as starting the bicycle with the pedals are taught.

A motorised scooter comprises a framework for supporting a rider; a ground engaging element connected to the framework for moving the rider; an engine connected to the ground engaging element for propelling the ground engaging element; and a brake further connected to the framework, the ground engaging element, the engine or a combination of any these for stopping the motorised scooter. A method for using the motorised scooter comprises a step of a first step of receiving a request to use at least one motorised scooter; a second step of notifying location of the at least one suitable motorised scooter; a third step of offering the at least one suitable motorised scooter; and a fourth step of getting back the at least one suitable motorised scooter.

A rear fork of a bicycle frame. The rear fork includes a base, a first arm, and a second arm. Each of the first arm and the second arm extend rearward from the base. At least one wheelie step is coupled to the rear fork. The wheelie step includes an extension rotatably coupled to and extending from one of the first arm and the second arm, and a foot step coupled to the extension. The extension is configured to rotate along an axis extending in a direction from the first arm to the second arm. A lock is configured to lock the extension to the one of the first arm and the second arm at different rotational positions along the axis.
