A riding machine with a single wheel, a seat on a post above it, and pedals fixed straight onto the wheel — no handlebars, no chain, no second wheel to hold you up. Staying on one takes real practice, because you must balance forwards and backwards as well as side to side, and you steer by twisting your body.

A riding machine with a single wheel這是一種只有一個輪子的騎乘工具, a seat on a post above it輪子上方一根柱子撐著座位, and pedals fixed straight onto the wheel踏板直接裝在輪子上 — no handlebars, no chain, no second wheel to hold you up沒有握把、沒有鏈條，也沒有第二個輪子讓你保持平衡。Staying on one takes real practice要騎得住需要真的練習, because you must balance forwards and backwards as well as side to side因為你得同時抓前後和左右的平衡, and you steer by twisting your body而且是靠扭動身體來轉向。

Most people meet unicycles at a circus, at a street performance, or in videos of people doing tricks; a few use them to get around, and there are mountain unicycles for rough ground. Note that the pedals turn with the wheel, so you cannot coast — stop pedalling and you fall.

Most people meet unicycles at a circus, at a street performance, or in videos of people doing tricks大部分人是在馬戲團、街頭表演，或特技影片裡看到獨輪車的; a few use them to get around也有少數人用它代步, and there are mountain unicycles for rough ground也有專門在崎嶇地形上用的登山獨輪車。Note要注意 that the pedals turn with the wheel踏板是跟輪子一起轉的, so you cannot coast所以你沒辦法滑行 — stop pedalling and you fall一停止踩踏就會摔。

As a verb, to unicycle means to ride one, though people usually say 'ride a unicycle' instead. The word carries a small flavour of showing off a difficult, useless-looking skill, which is why 'he can juggle and unicycle' sounds funny rather than impressive in an ordinary conversation.

As a verb作為動詞, to unicycle means to ride oneunicycle意思是騎獨輪車, though people usually say 'ride a unicycle' instead不過大家通常還是說'ride a unicycle'。The word carries a small flavour of showing off a difficult, useless-looking skill這個字帶有一點炫耀一項困難但看起來沒什麼用的技能的味道, which is why 'he can juggle and unicycle' sounds funny rather than impressive in an ordinary conversation這也是為什麼「他會雜耍又會騎獨輪車」在一般對話裡聽起來好笑，而不是厲害。
