Question

   As we all know that there are still many electric bike riders in the world. When someone laughs at those who ride bikes instead of driving the car,it's really hard to laugh at anyone riding the sleek (光滑的) looking Shadow ebike,as what its makers’ saying,that is “ the world's first wireless (無線的) power-assist electric bicycle”.

   The almost entirely wire-free ebike has no brake or gear cables (剎車與齒輪) ，and no ugly wires in all parts of it. All the necessary wiring and electronics that do exist,are tucked away inside the bike's front wheel. That includes the motor,lithium polymer battery and the Daymak Drive controller,which wirelessly keeps the bike going.    If your cell phone is running out of juice,the wheel also has a USB port,a charging port,and an LED battery power display.

   The Shadow ebike is currently selling for $1,999,which is clearly an expensive way to bike to work—but hey,at least you know your cell phone will be charged.

 障礙句分析

All the necessary wiring and electronics that do exist,are tucked away inside the bike's front wheel.所有確實存 在的必要線路與電子設備都藏在了前車輪中。

that do exist是定語從句，修飾先行詞wiring and electronics,意為“確實存在的”；are tucked away意為“被藏 起來”，是一般現(xiàn)在時態(tài)的被動語態(tài)，結構:am/is/are +動詞的過去分詞。
