如题,双12入了台8.5a的,抬起车轮空转就29,站上人27已到头,还是不逆风的情况下,有定速功能,充满电跑了15公里左右掉了一格电,跑的时候如果把油门推到头或上坡那个电量显示柱子会往下掉,即使满电的情况下,但停下来又回升到正常电量,这个正常么?
我到手这个前轮右侧只有两个螺丝固定~~其他的好像是漏了装,也不知道是不是我骑了一天就颠簸掉了……左侧断了一颗螺丝……可通是我撞到了……![](http://static.tieba.baidu.com/tb/editor/images/client/image_emoticon33.png)
好在这螺丝5金店有售,并买了螺丝胶固定好,接下来再观察观察会不会掉螺丝了
,另外想问问如何把速度提上去一点点……比方上到30公里时速……
