Riding a bicycle is definitely a green act as it produces zero emission and consumes no energy to get moving. Designer Ignacio Ojanguren Alvarez give the eco-friendly a new purpose with his wonderful project called the Bike Lamp. In order to light the lamp, someone should be riding and start peddling the bike. This design really shows sustainability, for as long as somebodyâ€™s riding the bike, the lamp will surely light up. Peddling the bike will definitely be a great exercise for everyone who wanted to be physically fit while contributing something to the environment in his or her own little way.
