我买了一部连打气筒的自行车。

I bought a bike with its pump.

机车的周围放在空气筒，烟筒等等。

An air tank and a chimney that was removed to a circumference are left.

头盔由带特殊的运动传感器的小氦气筒组成。

The helmet is made of a small, helium gas cylinder with special motion sensors.

而且抽气筒还安有一个木制的把手用来防止手被烫伤。

And the pump has a wooden handle to prevent burns to the hands.
