I had to replace the touch screen on my Flash v.1. Customer support helped me diagnose the problem and I ordered a new display that arrived in 2 business days as promised. They provided a link to an installation video that was one of the most well done tutorials, I’ve ever used. Removal of the old one and installation of the new was without a problem. They included a special torch tool that I wouldn’t have had, and a new speaker in case the one attached to the display was damaged. I couldn’t have been happier when it was done and a touch of my finger brought the code entry screen back like new. Without the display I couldn’t manually operate the bike. I was able to ride the bike using the phone app prior to fixing it. I’m 73 years old and very pleased with my bike and the support I’ve received from the company. I’ve had my bike since the beginning of their production and it’s been very reliable and great fun to ride.
