There’s a new outdoor sport called snow biking for extreme sports athletes. Imagine a cross between a dirt bike and a snowmobile. Unlike snowmobiles, snow bikes are generally much lighter, and the narrow body is easier to ride. They were invented during World War II. However, the trend in snow biking didn’t take off until 2009, when a group of motocross bikers in the US began fitting dirt bikes with skis and snowmobile treads.
有一項適合極限運動員的新戶外運動稱為雪地單車。想像一下越野摩托車和雪上摩托車的結合體。與雪上摩托車不同，雪地單車一般要輕得多，狹窄的車身更容易騎乘。它們是在第二次世界大戰期間被發明的。然而，雪地單車的風潮直到 2009 年才開始興起，當時美國的一群越野摩托車騎士開始在越野摩托車上安裝滑雪板和雪上摩托履帶。
