Have you ever thought about making a bicycle that you dream of? Some creative people have invented some special bicycles. Here are three of them.

Bambikes

Bambikes are produced in a company in Philippines. They are made of an unusual kind of bamboo and other materials like metal and a local plant. They are very strong. And they are a perfect combination (结合) of the greenest building material and common bicycles. By making bambikes, the company offers jobs to the local people. Besides, it provides money for some students in its community to pay for their study. To continue the production, the company plants more bamboo than it cuts.

The heaviest bicycle

A German cycling lover, Frank Dose, has recently made the world’s heaviest bicycle with big old wheels and lots of other waste materials. He created it just because he made a bet (打赌) with his friend. The bicycle weighed 1.08 tones. It broke the world record of its kind in weight. Frank said his bicycle was surprisingly easy to ride although it had a huge size and weighed a lot. He rode it in front of 5,000 people for over 100 meters to prove it.

Twisted (变形的) bicycles

Two brothers in France created a bike that looks strange to ride and twists in the middle. Riders can make tight turns (急转弯). The brothers say the bicycle is hard to ride so it can stop people from stealing it. In fact, it isn’t as hard to control as you think. It takes a day or two to get used to the crazy way of riding. It’s amazing. So far, there have been 30 of the bicycles, but they are not for sale yet.
