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).

A portable Double Folding bicycle comprising a front wheel, a frame assembly and a rear wheel, the frame assembly comprises a handlebar, a front frame, a crossbar assembly, a rear frame and a saddle, the handlebar is detachably connected to the upper end of the front frame; and the crossbar assembly comprises a front crossbar, a middle crossbar and a rear crossbar, the rear end of the front crossbar is connected to the front end of the middle crossbar through a first folder, the rear end of the middle crossbar is connected to the front end of the rear crossbar through a second folder, and the saddle is detachably connected to the rear crossbar, with the inclination angle of the first folder being 58-62, and the inclination angle of the second folder being 89-94. The present invention facilitates the bicycle dragging and improves the overall usability of the bicycle.

A bicycle control apparatus is basically provided with a controller. The controller includes a processor, a memory, and an I/O interface. The controller is arranged to communicate with an assist mechanism of a bicycle. The assist mechanism includes an assist motor arranged to impart a supplemental drive force to the bicycle to supplement a manual drive force of the bicycle. The controller is programmed to alternately set a first control state or a second control state. The controller controls the assist motor such that an output state of the assist motor with respect to a manual drive force of the bicycle is different in the first control state than in the second control state.

The invention relates to a control device for controlling an engine driven transport apparatus. The control device comprises a fitness apparatus having a base part and at least one movable part movable with respect to the base part for enabling a user to perform a physical exercise. The control device further comprises a sensor device for sensing a degree of physical exercise. The control device is arranged for controlling engine power of an engine of the transport apparatus at least partly based on the sensed degree of physical exercise. The fitness apparatus comprises a flywheel rotatably connected to the base part. The fitness apparatus is arranged for setting the flywheel into motion by means of at least one of the one or multiple movable parts. The sensor device is arranged to sense the degree of performed physical exercise at least partly by sensing a degree of motion of the flywheel.

A vehicle with a front wheel and a front wheel of a vehicle is provided. The front wheel is drivable by a first drive arrangement, and a rear wheel of the vehicle is drivable by a second drive arrangement. The first drive arrangement may be integrated into the front wheel, and includes an electric motor for selectively rotatably driving the front wheel, a reduction gear between the electric motor and the front wheel, and an actuable coupling for selectively coupling or decoupling the electric motor to the reduction gear.

A method, system, apparatus, and/or device for propelling a non-motorized vehicle forward. The method, system, apparatus, and/or device may include a frame, a first wheel, a second wheel, a motor, a controller, and a bracket. The frame may attach to the first wheel, the second wheel, and the motor. The first wheel may attach to a first side of the frame and rotate about an axis. The second wheel may attach to a second side of the frame and rotate about the axis. The motor may connect to the first wheel, where the motor is configured to rotate the first wheel to propel the apparatus forward. The controller may control a speed at which the motor rotates the first wheel. The bracket may attach to a front of the first frame and connect to a non-motorized vehicle.

A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.
