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 (无线的) power-assist electric bicycle”.

   The almost entirely wire-free ebike has no brake or gear cables (刹车与齿轮) ，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.

 障碍句分析

All the necessary wiring and electronics that do exist,are tucked away inside the bike's front wheel.所有确实存 在的必要线路与电子设备都藏在了前车轮中。

that do exist是定语从句，修饰先行词wiring and electronics,意为“确实存在的”；are tucked away意为“被藏 起来”，是一般现在时态的被动语态，结构:am/is/are +动词的过去分词。
