Background Art

In a general, a bicycle is a two-wheeled vehicle in which a pair of wheels are rotated and moved by the human power and the power kicked by the human

feet is transferred to a rear wheel, via a pedal, a crank, and a chain.

A rate of a speed change is made to be changed according to a running condition and thereby the running speed may be adjusted. Such bicycle must have a plural of saddles on its frame itself to constitute a high-occupancy cycle and also a driving part must be provided with in such bicycle as much as predetermined numbers according to a number of saddles. In such high-occupancy bicycle, the installation of a plural of chains to be driven in such bicycle must inevitably accompany with a big power because a plural of sprockets to be driven in case of a two-occupancy functions as a load resulting from being engaged with one chain and therefore the human big power must be required to running in such bicycle.

In addition, its frame itself must be manufactured as a high-occupancy and so it is to increase a layout, a production equipment, and a manufacture cost according to the production of a bicycle for a special use.

Therefore, it has been suggested that a development is required with a high-occupancy cycle capable of individually adhering with the coupling of a plural of one-occupancy cycles.

Moreover, a structure that a frame itself at a bicycle may be coupled to a ricksha must be changed in case of coupling the ricksha to the bicycle and the coupling of a connection part to a rotation sphere to be rotated is made to be used so that a position change may be adopted according to a weight of the ricksha and a bicycle steering and therefore it is uneconomic to specially manufacture a bicycle for a ricksha.

At this time, a bicycle changed in its structure muse be used only for a ricksha because the bicycle may be not suitable for using a bicycle itself in the state of removing a ricksha and therefore, it is low to have a use efficiency resulting from reducing a universal scope of its use.
