Sturdy and build quality feels good. Is quiet and smooth. Build Instructions were easy enough as much of the bike is already built. Take away 1/2 a star only as I felt the Instructions on how to setup the User settings could be better. I chose this bike over the Reebok equivalent as Reeboks have quite a few negative reviews that it starts squeaking after prolonged use. Delivery was swift but was dumped on my front door step as I was out. Message I received was that delivery would be left with neighbour if not in. Another half star deducted for Delivery. Wife had to get neighbour to help her move it out the way to get into house.
