Hello All , I'm new to the forum and just got a new Qlink 200 as they are called in the US . I've got about 250 km on this bike and have enjoyed it alot so far but have one problem to run by you guys. The front brake seems to be chattering or vibrating a bit on one place on the disc . This happens when rolling along- not when the brake is applied . The braking is fine with no pulsing or any other problems. I thought it needed to be broke in or run in to seat itself but it's not getting any better so far . Has anyone had this problem ,or does anyone have any suggestions ? Thanks
