My favorite sport is riding a bicycle, the bicycle is small terrestrial vehicles, people ride on the bike , and the feet pedal as a driving force, the bicycle can be an environmentally friendly transport tool to ride instead of walk trip! More and more people use the bicycle as a fitness equipment to practice and to go on a journey! The bicycle itself is a sport!-------------------------------------------------------------------------------------------------------------------你认可我的回答么~~~如有不懂,可以追问~~~^.^
