Very clean line, would buy it again
Great attractive bar tape! Nice to the touch andvery comfortable❤️
Great product with super friendly staff. Definitely recommend to all
It works as wat is supposed to but loose on my most integrated bar but its suffice
Chain & cassette are super clean,,just as prescript to use, soak it for 2-3 mins; it would be better to use a toothbrush to brush through the chain & cassette. Thanks to the young staff who recommended.
你好！关于这个车灯，我的经验是：
对于山地车（MTB）骑行来说，我觉得这个灯是真的很好用。不过，如果是公路车，我个人就不推荐了。
完美整合： “我最喜欢的是它能完美地安装在 Quick Lock 手机支架的下方。Quick Lock 上面放着电话导航，而这盏灯就在电话下方，这样我的把横位置就非常整洁，一次性解决了手机和车灯的安装问题。
满足日常需求： 对于山地车来说，因为主要是在马路上保持能见度，提醒别人前面有车过来，这个灯的亮度是完全足够的。山地车在马路上速度一般也不会太快，所以它作为日常安全警示灯非常到位。不占空间： “这种整合式的安装方式，特别适合把横（车把）空间有限的山地车。
我不推荐给公路车的原因是：公路车速度快得多，如果晚上骑行或者需要照亮路面，它可能在亮度上会不够用，需要一个更强大、专用的照明大灯。这个灯的定位更偏向于警示/辅助照明。
