letting you know that they say warranty is on page 9, there is no warranty and no registration. The web site isn’t good either. I like the bike so I am praying no problems. Everything says see “your bike tech. if any problems. I couldn’t figure out how to turn bike on, ( it said switch on frame) I had to go to other bike brand and watch video. It is on Battery where indicator light is at. The instructions do not tell you how to use gears for pedaling and motor, if am going to have to play with it. So far motor only unless I turn off battery. ???
