我花了一个下午的时间在地面上安装了一个又大又重的地面固定装置，用一条非常长、非常重的摩托车链条把它们锁在一起。

I spent a recent afternoon installing a hefty ground anchor, to which my bikes are now attached with a very long, alarmingly heavy, motorbike chain.

但是，多数花费还是用在那条相当长的链条上，一些人可能不需要这些链条。

But a high proportion of this was spent on a particularly long chain, something people with a more sensible number of bikes won't need.

这条链条自身就有27,000英尺长。

The chain itself is 27,000 feet long.
