A two wheeled vehicle is propelled by the feet of a rider and hand-grasped poles when pushing against the ground. A forward wheel on a forward member and a rear wheel on a rearward member align along a longitudinal axis. The forward member rotates about a vertical steering axis. A saddle supports the rider. A torso brace allows the rider to balance and steer the device.

A supplemental drive mechanism for a bicycle or other manually compelled pedal vehicle providing a reciprocating handlebar assembly, a cable drive, a transmission assembly, and a supplemental drive assembly, wherein a forced reciprocating movement of the handlebar by a push-pull motion of a rider by the upper body, by and through the transmission, results in a singular direction rotational movement of a supplemental chain sprocket incorporated into the rear wheel drive of the bicycle in addition to a rotational pedal movement the rider by the lower body as applied to the pedals of the bicycle in a forward direction.

An all limb powered and steered front wheel drive land vehicle comprises a seat (133), a front wheel (115), a rear wheel (155), a front drive component (66) and a frame (1) wherein; the seat (133) and a rear wheel (155) are mounted on a rear portion of the frame (1); wherein the front wheel (115) and front drive component (66) are mounted on a front portion of the frame (1); wherein the front drive component (66) comprises a drive mechanism (61) for driving the front wheel (115) and a connecting rod (23)comprising two hand grips for driving the drive mechanism (61) and a lever (31) comprising two foot pegs for driving the connecting rod (23) and a fulcrum (105) mounting the lever (31) to the frame (1). Employing all four limbs of a comfortably seated rider for power and steering, this high performance bicycle converts into a tricycle by removing the rear wheel (155) and replacing it with an axle (192) and a left rear wheel (190) and a right rear wheel (191).

An electric bike comprises a front wheel, a rear wheel, a seat for a rider to sit on, a frame that supports the front wheel, the rear wheel and the seat, a driving device that provides moving energy to the electric bike and a braking device that reduces the speed of the electric bike. The driving device comprises one or more electric motors. The electric bike further comprises a pedal assembly that receives muscle power from the rider. The pedal assembly comprises a pedal axis and two pedals fixed to the pedal axis. The torque from the pedal assembly is not mechanically transferred to the front wheel or the rear wheel.

A gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) having a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by planet disk (B) which contacts the periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. A first freewheel (V1) is situated between the shaft (H) and flywheel (A) and a second freewheel (V2) is situated between the shaft (H) and centric disc (C).

Invention relates to the type of two wheel velocipede where the propulsion to the rear wheel is achieved by the use of riders legs/feet and propulsion to the front wheel is achieved by the use of riders arms and upper body on cranks that travel in circular motion using a single chain as a means to transfer force to the front wheel. An innovative step is the chest and upper body support pad which enables the rider to relieve strain of the back muscles and provide a surface against which to pull the handlebars.
