首先我(wo)們看(kan)(kan)外(wai)(wai)觀(guan)，就是(shi)(shi)看(kan)(kan)車子(zi)的(de)(de)(de)塑料件，拍打一(yi)(yi)下(xia)塑料外(wai)(wai)殼(ke)，如(ru)果(guo)聲(sheng)音渾厚的(de)(de)(de)話(hua)，證明外(wai)(wai)殼(ke)厚，會耐(nai)用一(yi)(yi)些的(de)(de)(de)。然(ran)后看(kan)(kan)一(yi)(yi)下(xia)外(wai)(wai)觀(guan)的(de)(de)(de)烤漆，是(shi)(shi)不(bu)是(shi)(shi)均勻，如(ru)果(guo)顏(yan)色很淡，可能車子(zi)就是(shi)(shi)庫(ku)存貨，放了(le)好(hao)長(chang)時間的(de)(de)(de)。接(jie)下(xia)來我(wo)們可以看(kan)(kan)一(yi)(yi)下(xia)外(wai)(wai)殼(ke)的(de)(de)(de)拼接(jie)是(shi)(shi)不(bu)是(shi)(shi)有縫(feng)隙，螺絲什么的(de)(de)(de)有沒有擰(ning)緊，這也是(shi)(shi)考量做工(gong)的(de)(de)(de)一(yi)(yi)個標準。外(wai)(wai)觀(guan)看(kan)(kan)完，我(wo)們可以看(kan)(kan)一(yi)(yi)下(xia)車子(zi)里面的(de)(de)(de)大架是(shi)(shi)否有焊接(jie)不(bu)均勻和脫漆的(de)(de)(de)現象，如(ru)果(guo)脫漆嚴(yan)重，則有可能是(shi)(shi)翻(fan)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。
   電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)作為電(dian)(dian)(dian)動(dong)車(che)和四大(da)(da)件之首(shou)要配(pei)件，其(qi)重要位置(zhi)可(ke)想(xiang)而知(zhi)，我們買新車(che)的(de)(de)(de)時(shi)候可(ke)以(yi)看(kan)一(yi)下(xia)(xia)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)壓，一(yi)應定(ding)要和車(che)架相匹配(pei)，然后要是(shi)(shi)(shi)(shi)全新未開封的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，有(you)(you)些電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)是(shi)(shi)(shi)(shi)維(wei)護或者周轉的(de)(de)(de)，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)上(shang)(shang)面(mian)也(ye)會有(you)(you)維(wei)護或者周轉字樣(yang)。最好的(de)(de)(de)話(hua)是(shi)(shi)(shi)(shi)要原裝電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)或者大(da)(da)品(pin)牌電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，原裝電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)上(shang)(shang)面(mian)一(yi)般有(you)(you)電(dian)(dian)(dian)動(dong)車(che)的(de)(de)(de)標識的(de)(de)(de)。看(kan)完(wan)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)我們就(jiu)可(ke)以(yi)看(kan)一(yi)下(xia)(xia)電(dian)(dian)(dian)機，通電(dian)(dian)(dian)以(yi)后，我們可(ke)以(yi)騎(qi)行聽一(yi)下(xia)(xia)電(dian)(dian)(dian)機是(shi)(shi)(shi)(shi)否有(you)(you)噪(zao)音(yin)，另外可(ke)以(yi)看(kan)一(yi)下(xia)(xia)電(dian)(dian)(dian)機上(shang)(shang)面(mian)是(shi)(shi)(shi)(shi)不(bu)(bu)是(shi)(shi)(shi)(shi)有(you)(you)電(dian)(dian)(dian)動(dong)車(che)品(pin)牌的(de)(de)(de)字樣(yang)，一(yi)般正品(pin)電(dian)(dian)(dian)動(dong)車(che)都是(shi)(shi)(shi)(shi)自主研發(fa)(fa)的(de)(de)(de)電(dian)(dian)(dian)機，會有(you)(you)自己的(de)(de)(de)品(pin)牌標識。接下(xia)(xia)來(lai)就(jiu)是(shi)(shi)(shi)(shi)看(kan)電(dian)(dian)(dian)動(dong)車(che)的(de)(de)(de)核心部件控(kong)制(zhi)(zhi)器(qi)(qi)，好一(yi)點的(de)(de)(de)控(kong)制(zhi)(zhi)器(qi)(qi)一(yi)直(zhi)使用的(de)(de)(de)話(hua)不(bu)(bu)會發(fa)(fa)燙的(de)(de)(de)，控(kong)制(zhi)(zhi)器(qi)(qi)上(shang)(shang)面(mian)也(ye)會有(you)(you)原廠(chang)銘牌的(de)(de)(de)。還有(you)(you)正規大(da)(da)廠(chang)出來(lai)的(de)(de)(de)電(dian)(dian)(dian)動(dong)車(che)控(kong)制(zhi)(zhi)器(qi)(qi)線束很整齊的(de)(de)(de)。最后就(jiu)是(shi)(shi)(shi)(shi)充電(dian)(dian)(dian)器(qi)(qi)了，原裝充電(dian)(dian)(dian)器(qi)(qi)上(shang)(shang)面(mian)會有(you)(you)車(che)子(zi)品(pin)牌標識，也(ye)有(you)(you)國(guo)家的(de)(de)(de)質量認證標準。最主要就(jiu)是(shi)(shi)(shi)(shi)充電(dian)(dian)(dian)器(qi)(qi)不(bu)(bu)要拿錯(cuo)，一(yi)定(ding)要和電(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)電(dian)(dian)(dian)壓相同。
