A device comprises: a handlebar having a longitudinal axis; a seat coupled to the handle bar; a line coupled to the seat; and a brake coupled to the line, wherein the handlebar is rotatable about the longitudinal axis such that the seat moves and thereby controls the brake via the line.

An operating device for a human-powered vehicle comprises a base member, an operating member, an accommodating structure, and a second electric power source. The operating member is movably coupled to the base member. The accommodating structure is configured to accommodate a first electric power source. The second electric power source is electrically connected so as to supply electricity to a wireless communicator. The second electric power source is separate from the first electric power source.

A brake system for a vehicle such as a bicycle is disclosed. The brake system may comprise an improved master cylinder assembly configured (e.g. manufactured/produced, assembled, etc.) so that a setting and/or adjustment of the brake stroke and/or lever action/actuation can be provided by any one independent mechanism (e.g. without any other adjustment mechanism) or by a combination of adjustment mechanisms (e.g. in a combination with one or more adjustment mechanism); operation of a mechanism for setting and/or adjusting the brake stroke may comprise a feature configured to engage a pushrod (e.g. by direct action on the pushrod or a feature of the pushrod or by indirect action through a link, adjuster, etc. configured to engage the pushrod). The master cylinder assembly may be configured to be set and/or adjusted/tuned within the indicated range to provide an intended performance and/or “feel” for the operator at the brake lever.

A snow vehicle having a combined brake and clutch handle is herein disclosed. Further, the snow vehicle can include a controller for managing operation of the snow vehicle, including shifting and engine management regiments, which can be selected by the operator depending upon operator preferences. Additionally, the snow vehicle can include an engine cooling heat exchanger for cooling liquid which is circulated through the engine.

An improved master cylinder for use with a hydraulic clutch or hydraulic brake system. The master cylinder has a master cylinder body defining a bore. A piston is configured to slide in the bore when an actuation lever is compressed by a user. Sliding of the piston as a result of the depression of the lever causes the piston to depress a spring and to increase hydraulic pressure in the hydraulic line leading to the brake or clutch. A spring is configured to return the piston when pressure is released from the actuation lever. The master cylinder body in some embodiments is configured for lateral position adjustment relative to a mounting bracket. In some embodiments the master cylinder has a reservoir. The reservoir can be oriented at a tilted angle relative to the body of the master cylinder. In further embodiments the master cylinder has an outlet nut that is configured for attachment to the hydraulic line. The outlet nut is configured such that removal of the outlet nut allows for access to the bore, including the spring and piston.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

Method for controlling a car, in particular a sports car, provided with a relative power train, relative braking devices and relative steering means, the method being based on a joystick comprising a lever, arranged in the car to identify a forward tilt and a backward tilt parallel to a longitudinal development of the car for interacting with said power train and with said braking devices, and two side tilts to the left and to the right for interacting with said steering means so as to determine a trajectory of the car, wherein the method, according to a first operating condition, comprises a first step of respectively associating said forward tilt and said backward tilt with a proportional forward and backward acceleration of the car.

A passenger side driving instructor brake controller can include a telescoping shaft including a first end and a second end, and a brake lever connector disposed at the first end of a telescoping shaft and adapted to be secured to a brake lever of a motor vehicle disposed within a driver-side front floorboard area of the motor vehicle. A tubular main body bent near its mid-section, the tubular main body configured to adjustably accept the second end of the telescoping shaft therein and secure the telescoping shaft with locking hardware at a fixed position within the tubular main body to enable the main body to traverse over a main console of the motor vehicle where the tubular main body is bent at its mid-section and also to extend into a passenger compartment area of the motor vehicle wherein the tubular main body can terminate at a handle area.

A lever device for hydraulically actuating the brake or clutch of a vehicle equipped with a handlebar may have a pump assembly with a pump body connected to the handlebar of a vehicle. The pump body may have a cavity, a piston operatively associated with the pump body so as to be adapted to slide inside the cavity along a direction of thrust (X-X). The lever device may have a control lever assembly rotatably associated with the pump body so as to rotate about a pivot axis (Y-Y), the control lever assembly may have at least one control level. The piston defines a stroke free play between an end position and a first operating position. The lever device may have a stroke free play adjustment device which is adapted to adjust the distance along the direction of thrust (X-X) between the end position and the first operating position.
