The most important and, perhaps, rewarding innovation in the realm of electric bikes is self charging e-bikes. However, people are still apprehensive about its credentials.

So, here is a detailed guide which may prove helpful to those seeking answers to such questions:

1. Is there an electric bike that self-recharges?

The technology that makes self recharging possible is known as ‘Regenerative braking’. It is often referred to as the ‘holy grail’ of e-bikes because it signifies infinite battery life dream.

Though, it is possible technically, but its practical implications present an all together different scenario.

For e.g. you have to drive the bike for 200 miles just to just to recharge your battery for another 20 mile ride.

2. How long one has to ride in order to fully charge the battery?

Theoretically, if you ride down a hill, your battery will automatically be charged. And wont even require a wall outlet or a charger. However, it can charge 10% of the driving range. So, if you drive around 20 miles downhill, your bike will be charged for another 2 miles. This can be extremely frustrating considering the battery will last only 10% of the ride’s total mileage.

3. Is pedaling required to recharge the e-bike?

Unfortunately, yes. The pedal power has to be provided so that regenerative process can work. Some companies advertise this recharge period as exercise mode to retain customer base. If seen in positive light, this can help you workout and in turn recharge your battery.

As far as apprehensions of some people regarding fully self recharging battery are concerned, they are true up to some extent. There practically isn’t a battery that will be magically recharged.

However, you can have a bike that recharges its battery if you are willing to work out a little. Some of the battery is also recharged without working out, while you are riding it to your office that is.

An average conversion or electric bike kit has a typical rating of around 350 watts.

Considering this, if you pedal and generate around 80 W of energy, it would take nearly 6 to 10 times longer to regenerate the lost energy.

As inefficient as it may sound, an electric bike still has the potential to save significant money which otherwise will be wasted on fuel. Add environmental, physical and maintenance benefits to it and you have a winning combination.
