Tri-Power Exercising device allows a rider to simultaneously, or on demand, exercise virtually all muscle groups in his lower and upper body. The device includes a bicycle frame, pedals, forearm bars, sliding seat, computer and electronic display recommending energy modulation amounts from various muscle groups to optimize physical performance on any given trek. Because riders can exercise virtually all muscle groups at once, they reduce their exercising time, continuously builds muscle tissue throughout their whole body, and exercises their cardiovascular and respiratory systems completely. Riders operate the device by rotating legs on the pedals, rotationally oscillating the forearm bars up and down with their arms and shoulders, and then use core muscles to pull and push the seat back and forth on the slider. Inverted racks, pinion gears, and one-way bearings turn this linear power from the oscillating forearm bars and sliding seat into torque that rotates the crank axle.

A child vehicle includes a power mechanism having a motor, at least one wheel selectively operatively coupled to the motor, and a propulsion switch coupled to the power mechanism and having a first position and a second position. The first position is from a user-initiated force. The propulsion switch automatically moves to the second position upon disengagement of the force. In the first position, the child vehicle is in the first operational mode and the wheel is being driven by the motor. In the second position, the child vehicle is in the second operational mode and the wheel is allowed to rotate substantially free from drag or resistance due to the motor. A method is also disclosed.

The present invention relates to a bicycle driving apparatus with a novel structure which allows a bicycle to move forward by alternately pushing each of both pedals in one direction. Since a user repeatedly presses down a left pedal (113) and a right pedal (114) to move a bicycle forward, the bicycle driving apparatus according to the present invention has an advantage of more convenience of use than a conventional bicycle driving apparatus in which the left pedal (113) and the right pedal (114) should rotate.

The herein invention presents new technologies for superior performance in bicycles, other human powered vehicles, and other mechanical systems; based on Wide Range Linear to Exponential CVT technology, Energy Saving Geometries, Short Stroke Independent Pedaling, and Reduced Friction Ball Bearings. Said new technologies are superior to prior art technologies in that they enable greater efficiency in the application of power and markedly reduce energy consumption, resulting in higher top speeds as well as much greater hill climbing power.

In an aspect, a self-balancing two-wheeled vehicle is provided, having a body, and first and second wheels rotatably coupled to the body. The second wheel has at least one lateral roller rotatable about an axis that is one of oblique and orthogonal to a rotation axis of the second wheel. At least one motor is coupled to the second wheel to control rotation of the second wheel and the at least one lateral roller. At least one sensor is coupled to the body to generate orientation data therefor. A control module is coupled to the at least one motor to control operation thereof at least partially based on the orientation data generated by the at least one sensor.

Vehicle (110) including a frame (114), a seat mounted to the frame (114), wheels (116, 118) rotatably mounted on the frame (114), and drive mechanisms (112) for causing rotation of one wheel (116). Each drive mechanism (112) includes an arm (132) pivotally attached to the frame (114) at one end, a weight (136) and attached pedal (138) at an opposite end of the arm (132), and a guide member (142) including a bump (150) and that moves in conjunction with movement of the weight (136). The guide member (142) has a first end region at which it is pivotally attached to the frame (114) and a second, opposite end region which is free. A roller (140) attached to the arm (132) moves along the guide member (142) during pivotal movement of the arm (132) to cause pivoting of the guide member (142) as the roller (140) engages with the bump (150). An energy transfer system (148) converts pivotal movement of the guide member (142) into motive power to rotate the wheel (116).
