We can build a QUAD-BIKE, and also we can design and fabricate it for an extremely low budget. It provides a platform for the undergraduate students to apply the principles of engineering science to expose their proficiency in the automotive world.The first main design goal is to keep the bike to maximum strength as possible. So, build the chassis and body out of AISI 4130 Alloy Steel. And for Steering Ackermann steering is a very important aspect of the steering system design. Applying this to Four-bar linkage steering.For to use the bike in All-Terrain the Quad-Bike needs to have a well designed and adjustable suspension system. A key component of the suspension design is the interface between the chassis and the suspension system. So,it is optimum require to use Double-Wishbone Suspension at Front and Mono-Suspension at Rear. Also for the power-train the best to use single front and reverse gear for easy shifting purpose rather than five to six gears which will complicate the driver to move on. For a Quad-Bike it is preferred to use two Disc brakes at front for two wheels and one disc brake on shaft also most commonly brakes use friction to convert kinetic energy into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic into potential energy in such stored forms as pressurized air or pressurized oil.Since the vehicle is an off-road vehicle it is better to choose tube less tyres for rear wheels and with bigger tyre threads. Less traction tyres provides high acceleration which is required for this QUAD vehicle.

Overall Quad-Bike gives a dignity, easy to move, solace to body for a farmer, and to every person to travel on any road.
