根據相關標(biao)準規(gui)定，電(dian)動自(zi)行(xing)車(che)(che)的最(zui)高車(che)(che)速，不(bu)能超(chao)(chao)過最(zui)高設(she)計(ji)車(che)(che)速，且(qie)不(bu)超(chao)(chao)過25km/h。本次(ci)(ci)(ci)電(dian)動自(zi)行(xing)車(che)(che)抽(chou)查有2批(pi)(pi)次(ci)(ci)(ci)的產品(pin)該項目不(bu)合(he)格，分別(bie)來自(zi)丹尼騎(qi)和(he)優速。其中1批(pi)(pi)次(ci)(ci)(ci)的實測值(zhi)25.4km/h，超(chao)(chao)標(biao)準值(zhi)0.4 km/h；另1批(pi)(pi)次(ci)(ci)(ci)的實測值(zhi)23.0km/h，并未(wei)超(chao)(chao)標(biao)準值(zhi)，但(dan)企業明示的最(zui)高設(she)計(ji)車(che)(che)速為18km/h，因實測值(zhi)超(chao)(chao)最(zui)高設(she)計(ji)車(che)(che)速被判為不(bu)合(he)格。

另外，本(ben)次(ci)(ci)抽(chou)檢的(de)三批次(ci)(ci)樣品照明不(bu)合(he)格，分(fen)別來自優速、愛(ai)瑪和賽箭(jian)。其中有一批次(ci)(ci)前燈不(bu)合(he)格，2批次(ci)(ci)后燈不(bu)合(he)格，均為亮度值達不(bu)到標準要求(qiu)。

在電(dian)(dian)動(dong)自(zi)行車蓄電(dian)(dian)池(chi)(chi)充電(dian)(dian)器(qi)不合(he)格項目上(shang)，兩款天能電(dian)(dian)池(chi)(chi)專用(yong)充電(dian)(dian)器(qi)樣(yang)品(pin)和(he)一款綠亮電(dian)(dian)動(dong)車專用(yong)充電(dian)(dian)器(qi)樣(yang)品(pin)不達標。

上(shang)海市市場監(jian)管局提醒，電(dian)(dian)動自行車(che)如果使用輸入、輸出線及插(cha)(cha)頭不(bu)合格的產品時，有(you)直接插(cha)(cha)在220V交流電(dian)(dian)上(shang)使用的風險，一旦(dan)出現這種情(qing)況，就有(you)可能產生觸電(dian)(dian)、起火等安全隱患。

對此(ci)，上海市市場監管局建(jian)議，電動自行車要根據自身的(de)(de)使用需求(qiu)選擇(ze)，并不是續行里(li)程越長越好；要選擇(ze)已取得(de)3C認證且(qie)常見的(de)(de)好口碑品(pin)牌，也要挑(tiao)選經營時間長信譽好的(de)(de)商家(jia)，可以確保售后(hou)服務得(de)到保證；不要追求(qiu)大功(gong)率和高(gao)車速。

同時(shi)，在(zai)給電(dian)(dian)(dian)(dian)動自(zi)行(xing)車充(chong)電(dian)(dian)(dian)(dian)時(shi)，謹防雨淋、高溫(wen)、陽光直射；不要(yao)在(zai)樓(lou)道內給電(dian)(dian)(dian)(dian)動自(zi)行(xing)車充(chong)電(dian)(dian)(dian)(dian)，不要(yao)飛(fei)線(xian)充(chong)電(dian)(dian)(dian)(dian)，盡量(liang)避(bi)免充(chong)電(dian)(dian)(dian)(dian)時(shi)間過(guo)長等情況；盡量(liang)避(bi)免電(dian)(dian)(dian)(dian)動自(zi)行(xing)車蓄電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)器顛簸；當充(chong)電(dian)(dian)(dian)(dian)器在(zai)充(chong)電(dian)(dian)(dian)(dian)時(shi)，嚴禁在(zai)表面用(yong)其(qi)他物品覆蓋。
