Electric Bike With Recycling Of Wasted Power is a new technological bike that is run by batteries as usual a commonly used electric bike do. But the difference in this “Electric Bike With Recycling Of Wasted Power” design is that this bike will recycle the wastage power on bike and reused it for next powering. We are building a electric bike which is powered by batteries to run its back wheel using powerful motor. And we also fit an electricity generator on front wheel to recycle wastage of power in braking system. This system can also be used conserve energy due to stored potential energy like when you are running down from hilly road or down from fly-over bridge.

Regenerative braking –
A lot of people inquire about regenerative braking. Hybrid car manufacturers often tout the ability to reclaim electrical energy when the car is going downhill. I don't know how much energy they are getting back in a car, but on a little electric bicycle, it is almost certainly never worth the added trouble, expense, and operational hassles. You would be much better off with a freewheeling setup. Let me explain how I've come to this conclusion.

B. BATTERY –
There is no question that the battery is the single thing, the one and only, overriding thing, that is holding back the development and mass proliferation of electric vehicles. At this point in time most of us are still stuck with using lead acid batteries. I am now using B&B 16 Ah batteries, made in China. Originally I used Hawker Odyssey batteries model PC545, 12 lbs. each, which are basically the same as the Hawker Genesis G13EP. All of the batteries I have used are deep-cycling, AGM (Absorbed Glass Matt) sealed lead acid batteries (SLA) and are about the best quality lead acid battery available.
SPEED CONTROLLER -
A speed controller or motor controller is essential in applying the voltage and power that is delivered to the motor from the batteries. All decent electric vehicles need a motor controller of some kind. On a bike with a very small motor it might be possible to just have an on-off arrangement, and I suppose there are other less expensive and much cruder ways to control speed but I feel that a decent controller is absolutely necessary with a powerful motor like this. The controller is a rather expensive electronic black box with no moving parts. A modern PWM or 'pulse width modulation'' controller is very reliable as long as it's current limit is not exceeded.

higher voltage system :36 or even 48 volts would be a lot better and keep the current draw down. I started with a 12 V system for simplicity's sake but the power was low and the current draw was high.
solar cell battery charger : They sell these to RV owners. Actually there's no reason why you couldn't throw a solar cell on your roof and charge the batteries all day. Imagine - this is real-world fully solar powered transportation, double today.
two-speed transmission : One speed for the hill and the other for the flat. Electric motors have such great torque throughout the RPM range that more than two speeds just isn't necessary unless the motor is severely underpowered. The obvious thing to me would be a hub motor with two or three speeds built in.
hub motor : the "hub motor" is the obvious solution for electric bikes, as used on Lee Iacocca's E-bike and the Wavecrest (which seems to have died and resurrected as the E+) and others. Heinzmann of Germany seems to still be making a variety of hub motors, as are other companies. Try Heinzmann's site www.estelle.de for some pretty interesting ideas - I guess they are now selling bikes, complete kits, motors, batteries and controllers. However, at this point they are still only about 300 watts = 1/3 HP which is about 1/3 of what they ought to be. Also, Heinzmann motors tend to be a little noisy and expensive.A hub wheel motor replaces the normal wheel hub and obviously needs no other transmission, chain, or belt which is a huge simplification - although of course this can also be a slight drawback in that the gear ratio can't be changed.
lithium ion battery : Certainl y the lithium battery has the greatest potential of all the next-generation chemistries. It has the most energy per pound and is well proven in smaller applications like cell phones and laptops.
