Unless your going to do a lot of downhill racing then there isn't much point in buying one as you have to get up the hill first before you can come down and as light weight is not an issue with downhill bikes, they are very heavy to get up hill with out the use of a tow rope or a ski lift.

除非你要做很多的下坡比赛则没有太大的意义之一，在购买你必须能够上山的第一个，然后才能来到这里，重量轻，是不是一个问题，与速降自行车，他们都十分繁重起床山丘出使用拖车绳或滑雪升降机。

Based on the equations, the position and attitude of micro flying robot with flapping wings can be controlled.For the rigid structure wing, a double rocker mechanism typical of two DOFs is designed, which is actuated by two PZTs. The mechanism can actuate the rigid wing to realize two DOFs movements. This mechanism has many characteristics, simple instructure, light in weight, reliable in movement, large in range, easy in drive and convenience in control.
