第一輛自行車
自行車的'歷史可以追溯到兩百多年前。1791年，西夫拉克伯爵在巴黎的一個公園裡向眾人展示並炫耀了自己的發明，一架被稱作“celeriferé”的雙輪車。它主要就是一個使用了很多年的兒童玩具的擴大版。西夫拉克的“celeriferé”有一個馬形狀的木框，兩端分別裝有一個輪子。坐上一個小座位便可以騎了，就像騎現在的自行車一樣，但雙腳要使勁蹬地——因為沒有腳踏板。操縱方向和剎車也是不太可能的，儘管有這些問題，這個發明在當時還是吸引了許多巴黎時尚的年輕人。很快他們便舉行了比賽，在街上到處騎。
當騎手嘗試最後衝刺時，受到一些小傷是很普遍的事情。控制那臺機器是很難的，改變行駛方向的唯一方法是拉起車前身，當前輪還在空中打轉時掉轉車頭。然而這種木製雙輪車並沒有流行很長時間，結合了沒有彈簧、沒有方向舵，以及遭遇不平整路段等問題，木製的雙輪車騎起來十分不舒服。儘管如此，這種木製的“celeriferé”還是現在自行車的始祖。
