The former is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium (water, air, road surface, etc.). The latter is the force exerted on a body by the air (or some other gas) in which the body is immersed, and is due to the relative motion between the body and the gas. Aerodynamic force arises from two causes: the normal force due to the pressure on the surface of the body and the shear force due to the viscosity of the gas, also known as skin friction. To be protected to the risk of injury the best solution is to fabricate the personal mobility which leads to the proper vehicle stability with its tilting wheel and cabinet cover body and also requires less traffic space as compared to the 4-wheelers with less fuel consumption.

The traffic conditions are bad and will be worst in the upcoming years. The big nasty part of our daily life is the commute and since the countries (like INDIA) are massively overcrowded and the vehicles are moving like molasses– they are just too big for the congested traffic. For the individual who like to drive the vehicles without affecting the traffic one can choose the VIPRA Bike Tilting Wheel Mechanism which inhibits the advantages of a 4 wheelers and eliminates the drawbacks of the 2 wheelers. According to Ali Behnood And Fred L Mannering Paper; A wide range of variables potentially affecting injury severities was considered including Driver - contributing factors, Location and Time of day, Crash-specific factors, Driver attributes, Road way characteristics, Environmental conditions, and Vehicle characteristics. To this they also considered the temporal stability behavior for individual parameters: 1. Driver’s gender 2. Physical condition of the driver. 3. Driver attribute 4. Roadway characteristics 5. Environmental conditions 6. Vehicle characteristic 7. Type of the vehicles 8. Vehicle occupancy With addition to these Aerodynamic Drag also plays an important role in vehicle stability. [1] II. Objective Of Fabrication To make the vehicle more potent and accessible than the normal 2-wheelers some innovations are done and they are as follows:  Tilting wheel increases the stability of the vehicle.  To decrease the aerodynamic drag of normal 2-wheeler cabinet system is introduced.  Comfort full drive of the vehicle over the long distances.  Seat belt makes it safer as compared to normal 2-wheelers. Types of Mechanism Used In Fabrication As the 2 wheeler have stability problem with their speed, since at slower speed there is the major problem with controlling the two wheelers with gear shifting and applying brakes due to which two wheeler stability decreases or say control over vehicle decreases there comes the two wheeler with tilting mechanism.
