Abstract - Today, million people rely on automobile
performance; however, there is an increase in range and speed with the new developments towards the E-bike. In 2007 E-bikes were increased by 10 to 30 percent of all two wheeled vehicles in major cities. In countries with dominant gasoline two-wheeler mode split, replacing those vehicles with electric bicycle could improve air quality and reduce greenhouse gases.
as their primary means of transportation. Compared to other modes of transportation, cars are the most efficient and convenient means of transportation. Unfortunately, most cars use fossil fuels and are very expensive to maintain in the current situation. So, E-cycle that looks a lot like a regular bike, with an external electric motor instead of pedaling power. In some cases, pressing the accelerator pedal will start the engine, compared to regular cycles, it is far effective for transportation. Electric bicycles are usually an alternative to both traditional bicycles and cars. This project aims to Fabricate an Electric Bicycle, which can be used for commercial purpose without muscular power. Here, the Ecycle is fabricated with the help of converter to boost the voltage from the battery.
2. PROPOSED WORK In general electric cycles comes with two 12V batteries which drives 24V dc motor, here we have been implementing this using a converter to replace a single 12V battery to reduce the weight of the bicycle. So here SEPIC(single ended primary inductor-converter)is used to boost the voltage of a single 12V battery to give sufficient power to drive the motor.

1. INTRODUCTION Due to the rapidly dwindling resources of petrol, diesel, and natural gas, the energy crisis is one of the primary worries in today's globe. In addition, environmental degradation is an additional component that contributes to resource depletion, which is a concerning warning. So, hereby our project provides a good solution for these problems. [1] Electric cycle, which is very efficient mode of transportation that comes with more advantages compared to traditional cycles and other motor vehicles. There are many types of bicycle available in market such as normal cycle that people need to peddle for it to move, motorized bicycle that uses fuel as its prime power and electric bicycle that can be sufficient for an hour, because of some weakness in the existence system, electric cycles came into picture.[2] Though there are electric cars and bikes available in the market, unfortunately electric cars tend to be expensive, mainly due to the cost of battery assembly. A four seater electric car being used to transport a single person is also wasteful of energy and also they requires parking spaces, costly, requires insurance and also need high maintenance.[3]
