首先(xian)我們(men)看(kan)(kan)外(wai)觀(guan)(guan)(guan)，就是看(kan)(kan)車(che)(che)子(zi)的(de)(de)(de)(de)塑(su)料件，拍打一下(xia)塑(su)料外(wai)殼(ke)，如果聲音渾厚(hou)的(de)(de)(de)(de)話，證(zheng)明外(wai)殼(ke)厚(hou)，會耐用(yong)一些(xie)的(de)(de)(de)(de)。然(ran)后看(kan)(kan)一下(xia)外(wai)觀(guan)(guan)(guan)的(de)(de)(de)(de)烤(kao)漆，是不是均(jun)勻，如果顏(yan)色(se)很淡(dan)，可(ke)能車(che)(che)子(zi)就是庫存貨，放了好長時(shi)間的(de)(de)(de)(de)。接下(xia)來我們(men)可(ke)以看(kan)(kan)一下(xia)外(wai)殼(ke)的(de)(de)(de)(de)拼接是不是有(you)縫隙，螺絲什么的(de)(de)(de)(de)有(you)沒(mei)有(you)擰緊，這也是考量做(zuo)工的(de)(de)(de)(de)一個標(biao)準。外(wai)觀(guan)(guan)(guan)看(kan)(kan)完(wan)，我們(men)可(ke)以看(kan)(kan)一下(xia)車(che)(che)子(zi)里面的(de)(de)(de)(de)大架是否有(you)焊(han)接不均(jun)勻和脫漆的(de)(de)(de)(de)現象，如果脫漆嚴重，則有(you)可(ke)能是翻新(xin)車(che)(che)。

   看完外觀，就是電動車的四大件了，電池、電機、電池充電器、控制器。
