This is an electric bike that I saw recently in Chennai. And there are very few bikes only have been introduced. The advantage of this bike over the normal bike is that it runs 50 kilometers for just 5 rupees of cost. As this bike runs on batteries the disadvantage is that it can run only that much distance in a day. By preferring this bike for a shorter distances we can save the environment from being polluted. I hope that in the future these disadvantages will be rectified and we get a electric bike that replaces the normal bike.
