Technology has disrupted the automotive industry having long lasting, profound, complex relationship with the aspects of manufacturing, safety and the environment. Efficycle being one of the front runner of promoting eco-friendly mobility, this 3 wheeled configuration vehicle also need to align with these advancements and learn from it. An Efficycle is a Vehicle that places the rider in a laid-back reclining position. Most recumbent riders choose this type of design for ergonomic reasons: the rider's weight is distributed comfortably over a larger area, supported by back and buttocks. On a traditional vehicle, the body weight rests entirely on a small portion of the sitting bones, the feet, and the hands. Most recumbent models also have an aerodynamic advantage; the reclined, legs- forward position of the rider’s body presents a smaller frontal profile.

3. INTRODUCTION
 Our Efficycle has been designed in Tadpole
configuration because of the fact that two wheels in
front offer excellent overall braking and overall
excellent handling
 This is a mechanically and electrically driven
vehicle
 It does not pollute the environment since it uses a
simple DC motor.
 The vehicle in the hybrid mode (both paddling as
well as motor driven) could achieve a top speed of
52 km/h as per calculations.

6. Fabrication
 Fabrication is the creation of metal structures by cutting, bending, and
assembling processes. It is a value-added process involving the creation of
machines, parts, and structures from various raw materials.
 Fabrication Process:-
1. Cutting 3. Welding
2. Grinding
1. Cutting:-
We have cut the stainless steel pipe with the help of hand grinder, using
cutting wheel of 4 inches of dia and 1.5mm thickness.
2. Grinding:-
After cutting the pipes, they are grinded as per the pipe profile for easy joint
while welding.

7. 1.Welding:- Welding is a fabrication process that joins materials,usually metal or
thermoplastics ,by using high heat to melt the parts together and allowing them to cool.
o We are using electric arc welding with the help of stainless steel electrode that joint
the material each other.
o Diameter of electrode is 2mm and length is 300mm.
