The main idea behind this project is to develop a hub-less or spoke-less wheel. This bicycle overcomes some drawbacks of the bicycle being used nowadays such as heavy design due to the presence of spokes, power consumption issues, space issues. The advantages associated with this bicycle are light weight due to the absence of hubs or spokes, additional space in the wheel due to the absence of spokes, aesthetic look to the design and lowered center of gravity. The bicycle runs with a “rack and pinion system” connected to the rear-wheel. The paddle gear is connected to the pinion whereas the pinion meshes with the internal teeth of the rear-wheel rim. This bicycle can be used to overcome the above mentioned issues and it's a great innovation in the design of the conventional bicycle which gives the operator a fresh feel while using it and it's awesome and very aesthetic when it comes to the appearance of the bicycle.

Such problems result in an increase in toxicity in the atmosphere, traffic issues, global warming and other environmental hazards. In this era of mass-fuel consumption, a bicycle can be a relief to the environment and can reduce the load and burden on petroleum and diesel reserves. In order to overcome the drawbacks of the bicycle being used nowadays, we, a group of Mechanical Engineers have come up with an ideology of a spoke-less bicycle, which we have named as “I-bicycle”. Modification in the design of the conventionally used bicycle is possible. The basic idea is to design a bicycle with a spoke-less rear wheel, using a “pinion and rack mechanism”. Idea is that the constraints that occur on a wheel are at ground level, on the outer periphery. A wheel without x axis enables to support the vehicle at the lowest point. The center of gravity is lowered for better grip. This design reduces the weight as well as it reduces human effort. The concept is to develop a spoke-less or hub-less wheeled bicycle. The benefits desired of this bicycle is to reduce the material used in the bicycle, to reduce the weight of the bicycle as there is absence of hubs or spokes, to provide increased safety while riding and to provide some space to the user so that he can accompany a storage box or can even install an electric motor if required. In addition to this, the development of a hub-less wheeled bicycle results in a reduction in effort applied by the driver while riding the bicycle.
