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 prone bicycle comprising a frame (1), a front wheel (2), a rear wheel (3), a drive mechanism (4) for driving the rear wheel (3), and a pedal mechanism (5) for driving the drive mechanism (4), in which, the front wheel (2) and rear wheel (3) are mounted on the front portion and rear portion of the frame (1), wherein: a forearm support member (6) is mounted at the frame (1) front portion, and a dynamic knee support member (7) having synchronous movement with the pedal mechanism (5) is mounted between the pedal mechanism (5) and the frame (1). Designed with multi-point dynamic and static supports, this prone bicycle improves riding comfort and efficiency and is combined with crawling fitness function.

A dual-drive prone bicycle comprises a frame (1), a front wheel (2), a rear wheel (3), a front drive component (4) and a rear drive component (5), wherein: the front wheel (2) and the rear wheel (3) are arranged at the front portion and rear portion of the frame (1); the rear drive component (5) comprises a rear wheel drive mechanism (51) for driving the rear wheel (3) and a treadle mechanism (52) for driving the rear wheel transmission mechanism (51); and a dynamic knee support member (53) having synchronous movement with the treadle mechanism (52) is provided between the treadle mechanism (52) and the frame (1). Designed with multi-point dynamic supports, this dual-drive prone bicycle improves riding comfort and efficiency and is combined with crawling fitness function.

The present invention disclose a continuously variable reciprocating prime mover. The feature of this continuously variable reciprocating prime mover is that the reciprocating rotatory motion of the legs is modified into the reciprocating linear flexion and extension of the legs, by which one leg is flexed while the other leg is stretching, the combined force of the legs can be multiplied by the force. After each linear motion stroke is completed, the reverse linear motion stroke is repeated, and the driving direction remains unchanged. At any moment of the full stroke of the reciprocating linear flexion and extension of the legs, both can generate 2 times of the instantaneous power equivalent to the maximum moment point of the circular rotation.

The invention relates to a vehicle, in particular a lightweight vehicle. The vehicle can be converted from a driving configuration to a seating configuration by reducing the distance between a front wheel structure and a rear wheel structure.

Vehicle includes a frame, a seat arranged on the frame, a wheel rotatably mounted on the frame, an elongate directional slider, a pedal on the directional slider that slides between first and second positions, a main drive chain connected to the first wheel, a main drive sprocket that rotates the main drive chain and thus the first wheel, a flywheel that rotates the main drive sprocket, and an energy generating system that converts sliding of the pedal on the directional slider into rotational force to rotate the flywheel. The energy generating system may include a first electrical coil assembly connected to the pedal, a second electrical coil assembly in connection with the directional slider and that cooperates with the first electrical coil assembly to cause generation of electricity, and an electrical motor that is powered by the generated electricity and is coupled to the flywheel to rotate the flywheel.

Transmission system for a manually powered vehicle includes a pedal, an overrunning clutch system having a drum, and a power link coupled at its ends to the pedal and drum. The drum has a circular portion and a fin extending radially outward from the circular portion. The power link passes over the fin and at least a part of the circular portion and has a free portion between the fin and pedal. Movement of the pedal causes movement of the power link and rotation of the drum. A transmission member is coupled to the clutch system and a rotatable drive sprocket connected to a wheel of the vehicle. Rotation of the drum causes movement of the transmission member and rotation of the drive sprocket leading to wheel rotation. Rotation of the drum in the direction opposite to the second direction does not cause movement of the transmission member.

The present invention relates to a recumbent vehicle (10), more particularly, it relates to a recreational electrically (38, 40, 42) and/or pedal-powered recumbent vehicle (10), specifically suited for use as a golf cart (100). The recumbent vehicle (10) includes a chassis (12), two front wheels (14A, 14B), a rear wheel (16), a reclined seat (18), a footrest (20) located forwardly of the rotary axis of the front wheel and an unobstructed load bay (22) between the chassis (12), the rear wheel (16) and a backrest of the reclined seat (18).

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 steering system may include a seat assembly, a frame assembly and a wheel. The frame assembly may include a steering tube that is rotatably disposed within a head tube with a cam at a top end and a pair of forks at a bottom end to which is coupled an axle of the wheel. An arm may be disposed on and rotatably coupled to the seat assembly, and rotatably coupled to a left armrest and right armrest. A steering rod may be coupled to the cam and to one of the arms, the left armrest or the right armrest, such that forward movement of one of the armrests causes the steering rod to be translated forward and the cam to rotate in one direction, and backward movement of the same armrest causes the steering rod to be translated backward and the cam to rotate in an opposite direction.
