根據相關標準(zhun)規(gui)定(ding)，電動自行車的(de)最(zui)高(gao)(gao)車速，不能超過(guo)最(zui)高(gao)(gao)設計車速，且不超過(guo)25km/h。本次(ci)(ci)電動自行車抽查(cha)有2批(pi)次(ci)(ci)的(de)產品該項目不合(he)格(ge)，分(fen)別來自丹(dan)尼騎和優速。其中1批(pi)次(ci)(ci)的(de)實測(ce)值(zhi)(zhi)25.4km/h，超標準(zhun)值(zhi)(zhi)0.4 km/h；另(ling)1批(pi)次(ci)(ci)的(de)實測(ce)值(zhi)(zhi)23.0km/h，并未超標準(zhun)值(zhi)(zhi)，但企業(ye)明示的(de)最(zui)高(gao)(gao)設計車速為(wei)18km/h，因實測(ce)值(zhi)(zhi)超最(zui)高(gao)(gao)設計車速被判(pan)為(wei)不合(he)格(ge)。

另外，本(ben)次(ci)抽檢的(de)三批次(ci)樣(yang)品照明不(bu)(bu)合(he)(he)格，分別來(lai)自優速(su)、愛瑪和賽(sai)箭。其中有一批次(ci)前(qian)燈不(bu)(bu)合(he)(he)格，2批次(ci)后燈不(bu)(bu)合(he)(he)格，均為亮度值達不(bu)(bu)到標準要求。

在(zai)電(dian)(dian)動自行車(che)蓄電(dian)(dian)池充電(dian)(dian)器不合格(ge)項目(mu)上，兩款天能(neng)電(dian)(dian)池專用充電(dian)(dian)器樣(yang)品和一款綠亮電(dian)(dian)動車(che)專用充電(dian)(dian)器樣(yang)品不達(da)標。

上海市市場監管局提醒，電動自(zi)行車如果使(shi)用輸(shu)(shu)入、輸(shu)(shu)出線(xian)及插頭不(bu)合(he)格的(de)(de)產品時，有(you)直(zhi)接(jie)插在220V交流電上使(shi)用的(de)(de)風險，一旦出現(xian)這種(zhong)情況，就有(you)可能產生觸電、起火(huo)等安全隱患。

對此，上海市市場監管局(ju)建議，電動自(zi)(zi)行(xing)車要(yao)根據自(zi)(zi)身的使用需求選擇，并不(bu)是續行(xing)里程越長(chang)越好；要(yao)選擇已取(qu)得3C認(ren)證且常(chang)見的好口碑品(pin)牌(pai)，也要(yao)挑(tiao)選經營(ying)時間(jian)長(chang)信譽(yu)好的商家，可以確(que)保(bao)售后服務得到(dao)保(bao)證；不(bu)要(yao)追求大功率(lv)和高車速。

同時，在(zai)(zai)(zai)給(gei)電(dian)(dian)(dian)(dian)(dian)動自(zi)行車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時，謹防雨(yu)淋、高(gao)溫、陽光直射；不要在(zai)(zai)(zai)樓道內給(gei)電(dian)(dian)(dian)(dian)(dian)動自(zi)行車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，不要飛線充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，盡(jin)量避免充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間(jian)過(guo)長等情(qing)況；盡(jin)量避免電(dian)(dian)(dian)(dian)(dian)動自(zi)行車蓄(xu)電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)顛(dian)簸；當充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)在(zai)(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時，嚴禁在(zai)(zai)(zai)表(biao)面用其他物品(pin)覆蓋。
