In the sense filed here, an e-bike is a small motorbike whose power comes from electricity, not petrol. You ride it as you would a motorbike; the e- tells you the engine is electric. In British English, bike often already means a motorbike, which is why a learner’s dictionary can file the word this way.

In the sense filed here在這裡收的這個義項裡，an e-bike is e-bike 是 a small motorbike一種小型摩托車，whose power comes from electricity動力來自電，not petrol不是汽油。You ride it你騎它 as you would a motorbike就像騎摩托車那樣；the e-這個 e- tells you告訴你 the engine is electric引擎是電動的。In British English在英式英文裡，bike bike often already means本來就常指 a motorbike摩托車，which is why這就是為什麼 a learner’s dictionary學習型字典 can file the word this way會把這個字這樣歸檔。

Though actually, the street and the shops do not fully match that tidy label. In a lot of everyday English — product boxes, news, cycling talk — e-bike much more often means an electric bicycle: it still has pedals, and a motor helps you. An electric motorbike or scooter is then called an electric motorcycle, e-scooter, or, in Taiwan, 電動機車.

Though actually不過老實說，the street and the shops街上和店裡 that tidy label跟那個整齊的標籤 do not fully match對不太齊。In a lot of everyday English在很多日常英文裡——product boxes產品的包裝盒、news新聞、cycling talk自行車圈的談話——e-bike much more often means e-bike 更常指 an electric bicycle電動輔助自行車：it它 still has pedals仍然有踏板，and a motor helps you馬達幫你出力。An electric motorbike or scooter電動的摩托車或速克達，is then called這時會叫 an electric motorcycle、e-scooter，or, in Taiwan或者在台灣叫 電動機車。

If you meet the word under “motorbike” in a dictionary, that is the meaning they filed; if you meet it in a shop, look at the picture — pedals or not — before you decide.

If you meet the word如果你遇到這個字 in a dictionary是在字典裡 under “motorbike”的 “motorbike” 底下，that is the meaning they filed那就是他們歸檔的那個意思；if you meet it in a shop如果是在店裡遇到，look at the picture先看看圖——pedals or not有踏板還是沒有——before you decide再決定。
