I have actually 3 issued with the bike after the first 100km one was only a lose screw, the second makes problems with the battery connection I found a solution for now. And the last one is a problem with the rear wheel that stucks, but the support is great and very helpful, the first two issues was fixt in a day by my self with help of support, the last issue is a little frustrating because is difficult to troubleshoot from remote. The experience in the first days before the problems Beginn was great, Good Design Good looking frame quality and the electrical support is intuitiv and easy to use. Al the thing that I prefer. Hope i could enjoy the bike as soon es possible again.
