Embodiment Construction
[0056] Now in conjunction with above-mentioned accompanying drawing, the technical solution of the present invention is further described:
[0057] exist Figure 1-Figure 2 The ones in the middle are the front view of the front part of the A2 exercise bike and the side view of the A2 exercise bike. As can be seen from the figure: the cyclist holds the handle (25) that is covered with plastic pipe with both hands while stepping on the pedal (5) to make the rear wheel (2) obtain forward thrust Rotate the hand gear (8), the hand gear (8) drives the ring drive chain (11), and the ring drive chain (11) drives the smaller transmission gear (21) installed at one end of the front wheel rotating shaft (20) to rotate counterclockwise. The small transmission gear (21) drives the front wheel (1) to also rotate counterclockwise, so that the lower edge of the front wheel has a tendency to slide backwards, and produces a backward static friction force on the ground, and at the same time, th...

The invention discloses a quick body-building bicycle and tricycle with manual pedals. A fork rod arranged above an inclined upper side of a front wheel and a rotating shaft of the front wheel are provided with a set of hand-rotating gear or a hand-rotating gear box or a hand push-pull gear rack as well as a transmission gear and a transmission chain thereof. A set of footstep plates, the transmission gear and transmission chain are installed in front of the rear wheel, or a set of footstep plates, the transmission gear and transmission chain are installed between the underneath of the fork rod above the inclined upper side of the front wheel and the rotating shaft of the front wheel, and one set of hand-rotating gear lever, the transmission gear and transmission chain are installed in front of the rear wheel. A rider pushes and presses the pedals with two feet so that the back wheel or the front wheel acquires the forward pushing force, and the hand-rotating gear or the hand-rotating gear box or the hand push-pull gear rack or the hand-rotating gear lever is rotated by using two arms so that the front wheel and the rear wheel can acquire forward pushing force. The body-building vehicle has the advantage of quickness of a locomotive vehicle, and a simple structure and energy conservation and environment protection of a bicycle, and overcomes the defect that the body is not exercised by riding the locomotive.
Description
technical field [0001] The invention relates to the field of mechanical parts installed on the fork lever and the rotating shaft of the front wheels of bicycles and tricycles, in particular to a manual pedal fast fitness bicycle and a manual pedal fast fitness tricycle. Background technique [0002] The serious defect of well-known current bicycle and tricycle is: only foot pedal and the larger transmission gear that is fixedly connected with it are installed under the vehicle seat, the less follow-up gear is installed on the rear wheel rotating shaft, with foot pedal A ring-shaped transmission chain is installed between the larger transmission gear fixedly connected and the smaller follow-up gear installed on the rear wheel shaft. The passenger can only step on the pedal with both feet to make the rear wheel get thrust, and the front wheel The handles on the wheels and forks only play a role in balance and steering. The front wheels cannot obtain thrust, so the maximum spe...
