First, the good. Assembly was fairly easy, although I was worried that the electrical connectors weren't properly mated. They were, and everything worked when I plugged it in. The bike is sturdy, quiet and smooth. The engineering is good and the variety of programs available from the console is good. But I found the documentation poor. As is often the case they guide you through all the menus, which is unnecessary - they're obvious. What isn't obvious to a beginner like me is how I should choose a program, how often I should repeat it, and so on. There's no help offered for this. And as for the Motion app - words fail me. I bought a tablet specifically for the purpose, which meets the stated requirements. Bluetooth connects, but the app won't connect with the bike. Many have the same problem (see the reviews on the Play store) and DKN appear not to give a fig. I was hoping the app would make up for the deficiencies of the documentation, but I can't even run it. In summary: a well-made piece of kit, but let down by the documentation and app. I'm still very pleased with it overall.
