One year, two Australians，Adam and Stephen，decided to go to Jamboree(童子军大会)by bike．It was in Sweden，about 20，000 kilometers from their home in Adelaide! They didn't take normal bikes；they took bikes with three wheels instead．These are more comfortable and easier to ride up hills．
They took everything they needed．They had a tent each，things to cook with，clothes，maps，computers and phones，and things to repair the bikes．They also took their passports (护照)because they planned to travel through 22 different countries．
The journey began in Australia but it didn't go well．After just a few days，Adam's bike broke．He left Stephen and went back home by coach (长途汽车)．He got a new wheel for his bike，then bought a plane ticket and flew to Perth．In Perth, he took a train to a town called Merridien．After he got off the train，he put his bike together and rode to meet Stephen．
After that，they flew to Johannesburg and then they began their bike ride though Africa. They slept in tents by the road，and in some places they saw a lot of wild(野生的)animals .One night, they could hear lions ,and another night , an elephant walked past their tents．
In Europe, they rode up some very high mountains．And the most wonderful thing， they thought，was that they saw snow for the first time in their lives．
In every country，along the way，Adam and Stephen met a lot of interesting people and had lots of interesting people and had lots of adventures(奇遇)．The journey took 269 days．
