An innovative bicycle kit that cantransform the normal bicycle system intoe-bike just in seconds.1.7 -Kundan Giri -Rajiv Ranjan Kumar -Ratnesh Chandra Srivastava -Ruchika Singh
What is E-KIT The E-kit is a modified version of THE COPENHAGEN WHEEL in which we have tried to eliminate all its limitations. E-kit is a kit which will transform any random cycle into an electrified vehicle while keeping it cheap and simple. We are actually dealing with design parameters of making this installation faster, sturdy and efficient. The mechanism is basically a wheel which can be affixed to any bicycle at any moment on users demand, quickly.
Need of E-KIT It can easily transform any common man cycle into an electrically driven vehicle very easily. Controllable assistance that can help the unfits start cycling regularly. Make it easer to travel further, regularly and carry more. Gives extra help going up hills and cycling into headwinds. Accelerating to cruising speed in a fraction of the time/ effort. Costs a fraction of the price to buy and run compared to bikes.

What is Copenhagen Wheel? The Copenhagen wheel is a bicycle wheel that can easily retrofitted into any ordinary bike. It’s sleek red hub not only contains a motor, batteries and an internal gear system, but also includes environmental and location sensors which are powered by the batteries in the wheel and provide data for cycle related mobile application.
Working principle The Copenhagen Wheel uses a technology similar to The KERS (Kinetic Energy Recovery System), which has revolutionized Formula One racing over the past couple of years. When you brake, your kinetic energy is recuperated by the electric motor and then stored by batteries within the wheel. It also occurs in exercise mode - where riders are working a g a ins t the motor, thus giving themselves a workout and in turn recharging the batteries in the hub.
G o a l o f The Pro je c t To reduce the rotating mass from the hub of the Copenhagen wheel. All components should be placed in a single hub. The wheel must be easily retrofittable into any standard bicycle. The bike must harvest energy through braking and pedaling by choosing one of three modes:- i. off ii. Motor Assist iii. Pedal Assist (Regeneration/exercise mode) The weight should be no more than a ‘heavy bike’ when fitted into a regular bike.
Advantages Environment friendly. Easily adjustable to any bike. Doesn’t create extra load on ride. Can be controlled by mobile phone. Ensures rider’s health safety. Encourages people to use cycle as a transport.
Disadvantages Have to use a mobile phone to get full functionality. Not available worldwide, specially in third world country like us. Not cheap for people having low income. Not good for too much hilly areas.
Example Power Assistance From An Electric Bike. 100%Applied power 0% 0 mph 15 mph 9 mph Speed
Methodology1. CAD design-we will try to give the local population an alternative to the mainstream cycles. This is to be done by designing from scratch the kit on CAD software.2. Prototype analysis-a prototype will be built which will basically transform the ‘hero’ into a electrified vehicle while keeping it cheap and simple.
Requirements Motor Type: 24 volt, 400 watt continuous / 800 watt peak power Battery Type: Dual 12 volt, 10 amp/hour, rechargeable battery pack Recharge Time: 3-7 hrs (with outlet charger) Top Speed: 15 MPH
Future prospects Vehicle of future - Leading automobile companies are keeping their eyes on it. Versatile application - Can be install in bicycle as well as in rickshaw and in other vehicles. In mass production cost of manufacturing will drastically reduce.
Ford e-bike Ford unveiled its new e-bike as a study on urbanmobility solutions.
The new Smart e-bike It will sell for under €2,900 inEurope.
Conclusion The Copenhagen Wheel project began by asking the question: how can we improve the cycling experience in order to encourage more people to ride bikes. The same spirit rides in our hearts and surely it will fulfill the goal by attracting more people for safe cycling.
