I just bought a mantis x pro ebike from rawrr at a dealer pre assembled and I am having an issue where every time that I pull either of the brakes the display cuts out. If I pull the brake lever very short it reboots itself and turns back on but still has the issue but If i pull it for more than one second the display remains off until the bike is rebooted. The issue only happens after I have drove the bike about 20ft out of my garage and the bike only has 35 miles on it. If anyone has advice it would be much appreciated I just deleted and reposted this so I could add the video.
