  1. What about the price of those electric bikes. Isn’t it still cheaper for bigger households to buy a car instead of electric bikes for each family member?

      The price of the electric bikes is around 400 dollars to 10000 dollars depending on what kind of e-bike you choose. Yeah, the price seems expensive. However, the e-bike does not require insurance (while compared with car), gas, and expensive parking. It is totally environmental friendly just as the normal bikes. The most important thing is, it is definitely good for your heath. In addition, due to the extra electric motor power, you can enjoy the speed without getting tired easily.
      I also found an video about a person’s feeling by riding e-bike. http://www.youtube.com/user/ElectricBikeReview
      Hope it is clear enough for you question.

  2. I wouldn’t go as far as to say that the bikes are totally environmentally friendly. You are still tasked with the fabrication of batteries and other parts that are energy consuming and not environmentally friendly, also when it comes to the recycling of these parts, especially batteries.

      Indeed, I agree with you. But e-bikes are more environmentally friendly than exhaust-spewing vehicles (as we all know, the greenhouse issue). In my new post, you can also look into the dark side of e-bikes, for example, the safety issue.
