首(shou)先我(wo)們(men)看(kan)(kan)外觀，就是(shi)看(kan)(kan)車子的(de)(de)(de)(de)塑料(liao)件，拍打一(yi)(yi)下(xia)塑料(liao)外殼，如(ru)果聲(sheng)音渾厚的(de)(de)(de)(de)話，證明(ming)外殼厚，會耐用一(yi)(yi)些(xie)的(de)(de)(de)(de)。然后看(kan)(kan)一(yi)(yi)下(xia)外觀的(de)(de)(de)(de)烤(kao)漆，是(shi)不(bu)(bu)是(shi)均(jun)勻，如(ru)果顏色很淡(dan)，可(ke)能(neng)(neng)車子就是(shi)庫存(cun)貨，放(fang)了(le)好長時(shi)間的(de)(de)(de)(de)。接下(xia)來我(wo)們(men)可(ke)以(yi)看(kan)(kan)一(yi)(yi)下(xia)外殼的(de)(de)(de)(de)拼(pin)接是(shi)不(bu)(bu)是(shi)有縫隙，螺絲什么的(de)(de)(de)(de)有沒有擰緊，這(zhe)也是(shi)考(kao)量做工的(de)(de)(de)(de)一(yi)(yi)個(ge)標準。外觀看(kan)(kan)完(wan)，我(wo)們(men)可(ke)以(yi)看(kan)(kan)一(yi)(yi)下(xia)車子里面的(de)(de)(de)(de)大架(jia)是(shi)否有焊接不(bu)(bu)均(jun)勻和脫漆的(de)(de)(de)(de)現象，如(ru)果脫漆嚴重，則有可(ke)能(neng)(neng)是(shi)翻新車。

   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。
