INNOVATIVE FEATURES The new feature of this vehicle is its Auto-Mode operation of motor. In this mode of operation the microcontroller (Atmega32) automatically switches the motor between motor mode and generator mode automatically as per the requirement. This is achieved with the help of difference de-amplifier, a comparator, a microcontroller, and high power MOSFETs. What the circuit essentially does is measure the back-emf generated by motor to determine at what speed the vehicle is running. It then compares this speed with the speed required as set by the accelerator. If, the speed is more than needed (or set), then the microcontroller automatically automatically switches form motor mode to generator mode by the help of high power MOSFETs. In this generator mode the battery charge is replenished. Thus, energy is restored during down hills, slopes, slowing down the vehicle or braking. It also includes multiple gears and gearbox to increase the load carrying capacity of the vehicle even when driven by a small boy. It also includes an electrical accelerator to control the speed of vehicle when the motor is switched on. There are ar e many other switches for various purposes and this also includes mechanical disc brakes and electrical brakes for safety. Other features include shock absorbers, topple protection bar and comfortable seats. Hence, these features increase the efficiency of the vehicle and thus can be called an “EFFI-CYCLE”.
COMMERCIAL FEASIBILITY A moment of thought into the future will easily give the realization that this vehicle is the basic design of the vehicles that will be used in the future. According to our Cost Report this vehicle cost around Rs. 20,000. But when this vehicle will be manufactured industrially, industrially, the cost is expected e xpected to go down to at least Rs. 15,000. In contrast to the normal petroleum based vehicles (like motorcycles, cars) which are costly, and whose price is not expected to come down, this vehicle is a great alternative. Again the cost of operating this vehicle will be much less than with the normal vehicles. As the price of this vehicle is less, more people will be able to afford it, which means there can be a great market ahead (just like it happened in case of mobiles). People are nowadays becoming aware of the environmental concerns and hence such people will be strongly intended to buy these vehicles instead of the polluting ones. For small business persons this can be a fast and cheap way of transport and hence this may help in reducing the market price of market products. When added to it, a nicely designed body (like a pointed car), comfortable seats, high power motor and high battery capacity added, this vehicle can take up a major part of the market in automobiles.

Unique Selling Proposition (USP) “Get your money back in 3 years and start earning afterwards!!”

Most of the people across the world spend a lot of money in travelling from their homes to their workplace. They do this by scooters, motorcycles, and cars (mostly in foreign countries). Not only does this result in a lot of wastage of money but also results in air pollution and today it is in fact the major cause of air pollution due to automobiles. This also results in tr emendous dependence dependence on petroleumbased resources and hence is the t he reason for non-preventable rise in the prices of both petrol and diesel. When people drive cars to drive to their workplaces, they are surely wasting a lot of energy in driving those huge-sized vehicles to carry t hem to their destination. This vehicle can solve this problem to a great extent. First of all, it is a light weight vehicle weighing only XXXX kg. This is because it is made of aluminum alloy which is very light. Again, it can be driven mechanically, or if you are tired, then it can be driven electrically as well, without disturbing you with any noise or polluting the environment. No need to waste money in buying cycles and a vehicle. This vehicle itself acts as both a two-seated tricycle(more stable than bicycle) and as a two-seated vehicle. So, you can now not only save energy consumption but also your money. For students, this vehicle is great since this vehicle has a proper speed control and cannot be driven faster that XXXX km/hr which enhances their safety. They will be able to carry their bags simply by keeping it in the rear carrier. This vehicle can also act as an inspiration to them to make efficient and environment-friendly vehicles in future.
