Unverified变速档位并非越多越好：市区平路通勤3-7速内变速已足够且免维护；只有需要爬坡或长距离骑行才需要8速以上外变速，外变速链条外露折叠时易蹭脏衣物89% similarUnverified内三速变速范围较窄，面对坡度较大的山地路段或城市连续爬坡时力不从心，平坦城市通勤表现更佳89% similarUnverified6速变速适合城市通勤丘陵起伏路段，若仅在平坦市区骑行，档位冗余；若需应对较大坡度长途则仍显不足84% similarUnverified城市通勤实际用不到超多档位，内变速3-7速或外变速7-9速已足够；21速以上多为营销噱头，档位重叠严重且链条易磨损，反而增加维护负担83% similarUnverified单程通勤＞8km或有明显爬坡路段，不建议买单速版折叠车，无变速上坡极累，应选内变速3速以上或外变速7速83% similar
