Many people wish to travel around the world，it seems like an impossible（不可能的） dream. 1 to a bamboo（竹子）bike，the dream isn't far away.
Matthias Kalla and his friend Sabine Metzger think of sending a bike around the world. They're both German students. They hope to collect 2 for a drinking water project by doing it.
"A person can go around the world，so why can't a bike?At last，we did the 3 thing with a bike，" says Kalla. Then they used a bamboo bike because bamboo is strong and 4 to environment.
The 5 behind the bamboo bike project is simple. If someone wants to6 the bike，he can get on www. bamboobike. com. And then he just need to write the route （路线） he wants to travel on this 7 . So all people who like this project will know where to get the bike.
Some people have already decided to 8 this activity. "We have a good network. Even though something goes 9 with the bike，it's sure to be back on the road soon," says Metzger.
Kalla and Metzger believe the bike is strong enough to finish the 10 .
