✔ 最佳答案
應該係大碌快D,省力D因為大碌的圓周比細碌大,所以前進的距離較大
如果用同一個速度,用大碌單車要踏腳踏的次數較細碌單車小
踏腳踏的次數小了,自然比較快,省力
PS.最重要的是我之前試過了,細碌單車用多很多力,但換了大碌單車
後,解鬆多了

大碌
because the circumference of the wheels are longer than 細碌
when you ride it(大碌),the distance that you travel is longer than細碌
so riding 大碌 is faster than 細碌

詳細:
既然你個碌大d,即係你踏一下,你travel既distance比細碌多,
既然大碌踏少d =>去到目的地
細碌要踏多d=> 先可以去到目的地
咁當然, 踏大碌係省力過細碌
