Vehicle including a frame, a seat, a wheel, a drive sprocket arranged on the wheel, a main drive sprocket, a transmission member coupling the drive sprockets, a pedal slider arranged in front of the seat and which swings forward and rearward, and a drive mechanism including an overrunning clutch system connected to the main drive sprocket. A power link is connected at a first end region to the pedal slider and at a second end region to the clutch system. Forward movement of the pedal slider causes movement of the power link and rotation of the clutch system which causes movement of the main drive sprocket and the wheel drive sprocket resulting in rotation of the wheel. A roller is arranged on the frame to guide the power link in a substantially horizontal plane in a portion between the roller and the pedal slider.

A novel cycle device including a transmission assembly (or assemblies) that significantly reduces torque interference with steering operations is provided. Such an assembly is provided in one or more of a modular, fixed or movable configuration according reduced complexity of implementation, improved efficiency of operation, and useful assembly modularity for manufacture and repair. Such a device may further include an improved means for selecting between direct and overdrive functions of a fixed transmission assembly. Additionally, a removable front transmission assembly comprising a steering fork with handlebars is also encompassed herein.

A cycle includes a fork and a first wheel is mounted to the fork. A steerer tube is connected to the fork. The steerer tube has a longitudinal axis. The cycle includes a pair of second wheels. A pair of downtubes is rotationally mounted to the steerer tube about the longitudinal axis. The pair of downtubes have a fixed inclination with respect to the longitudinal axis. Each one of the down tubes respectively connects one wheel of the pair of second wheels to the steerer tube for pivoting the pair of second wheels together and apart.

A motorized self-balancing vehicle is provided. The vehicle may include at least two wheels. The vehicle may include a self-balancing mechanism. The vehicle may include a manual-drive mechanism. The self-balancing mechanism may constantly update the self-balancing vehicle in order to maintain the balance of a rider of the vehicle, while the rider is engaged in human motion on the manual-drive mechanism. The human motion may include pedaling and/or stepping. The vehicle may include an electric motor. The vehicle may include only an electric motor. The vehicle may include only a manual-drive mechanism. The vehicle may include both the manual-drive mechanism and the electric motor. In the embodiment including the manual-drive mechanism and the electric motor, the power generated by the electronic motor may be combined with power generated by the manual-drive mechanism in order to move the vehicle.

A handlebar assembly is able to attach to a bicycle. The handlebar assembly provides a higher grasping point for a bicycle operator than the original handlebar, enabling the operator to lean back and assume a recumbent posture while riding. The handlebar assembly includes and attachment member, a handlebar member, and an extension vertically separating the two components. The attachment-member is able to affix about the existing tubular handlebar of the bicycle by means of a clamp.

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.

A pedal operated vehicle includes a frame and a drive wheel rotatably coupled to the frame. In addition, the vehicle includes a pedal assembly coupled to the frame and including a pedal sprocket. Further, the vehicle includes a transmission mounted to the frame. The transmission includes an input sprocket mounted to a rotatable first shaft and an output sprocket mounted to a rotatable second shaft. A first chain is disposed about the pedal sprocket and the input sprocket. The output sprocket is configured to drive the rotation of the drive wheel. Moreover, the transmission includes a first plurality of sprockets coupled to the rotatable first shaft and a second plurality of sprockets coupled to the rotatable second shaft. A second chain disposed about one sprocket of the first plurality of sprockets and one sprocket of the second plurality of sprockets.

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.

A self-balancing load-bearing device having a load platform or like structure that may move relative to the drive wheel or wheels under the force of gravity as the device operates. The load platform may be mounted with a pendulum based structure including curved support tracks or pendulum arms or a related structure. User input of control signals may be achieved with a joystick, foot pedal, remote control or other. Various embodiments and uses are disclosed.

A configurable cycle vehicle (10) has an adjustable frame (12) which is formed from a plurality of relatively configurable frame members (26, 28, 30, 32, 34), and which can be separately arranged in a first, upright riding condition, or alternatively in a second, recumbent riding condition. A method of conversion of a cycle vehicle between first and second riding conditions is also provided.
