A cycle (10) having a drive mechanism (20) comprising input and output assemblies (22, 24), and a transmission system functionally connecting therebetween for transmitting motion from the input to the output assembly is disclosed. The input assembly (22) defines a drive axis (32) via which an input force is provided, and first and second drive points (30) spaced from the drive axis (32), and is configured to harness the input force to produce an angular motion of the drive points about the drive axis (32). The output assembly (24) defines a wheel axis (38) and first and second wheel points (36A, 36B) spaced therefrom, and is configured for being driven by the angular motion of the drive points to rotate the wheel points (36A, 36B) about the wheel axis (38). The transmission system comprises first and second transmission members (40A, 40B) pivotally articulated, at first ends, with respect to the first and second drive points and, at second ends, with respect to the first and second wheel points (36A, 36B).

A bicycle control device includes an electronic controller that controls a motor, which assists propulsion of a bicycle. The electronic controller is configured to decrease an output of the motor to less than or equal to a limit value upon determining a shifting device is performing a shifting action to change a transmission ratio of the bicycle. The electronic controller is further configured to change at least one of the limit value of the output of the motor and a time in which the output of the motor is decreased upon determining the shifting device is performing the shifting action in accordance with at least one of an actuation state of the shifting device in the shifting action and a parameter of the bicycle that is changed by the shifting action performed by the shifting device.

A drive assembly for a human-powered machine may include a front crankset spaced from a rear crankset, each rotatably coupled to a frame. Crank arms of the rear crankset are longer than crank arms of the front crankset. A left foot platform and a right foot platform each have a rear portion rotatably coupled to a distal end portion of the corresponding rear crank arm, and a front portion in sliding and rotating engagement with a distal end portion of the corresponding front crank arm. The front crankset and the rear crankset may be mechanically coupled to each other, such that the two cranksets turn together at the same rotational speed in terms of RPM. The two cranksets may also be operatively connected to the hub of a wheel

A bicycle control apparatus is basically provided with a manual drive force detecting device, a rotation state detection device and a controller. The manual drive force detecting device detects a manual drive force. The rotation state detection device detects a parameter relating to crankshaft rotation of a crankshaft. The controller is programmed to control at least one of a driving unit that generates an auxiliary drive force and an electric transmission unit so that the manual drive force and the parameter relating to the crankshaft rotation will be within a prescribed range.

The function of this invention is to provide exercisers with a safe and easy way to convert a legs-only exercising device, such as a stationary trainer or bicycle, with the capacity to exercise their upper and lower body muscle groups simultaneously or separately. This invention is portable and can be moved easily from one legs-only exercising device to another. Once they are mounted onto the handlebar or attachment bar of the legs-only device, it is now a full-body trainer. Exercisers mount the trainer, place their feet on the cycling pedals, place their elbows onto the elbow holders, grasp the hand grips, and now start their full body exercising activity. The degree of difficulty of their exercise trek is easily accommodated by allowing the rider to adjust the resistance for moving the forearm bars up and down for an upright bike, or back and forth for a recumbent trainer.
