Manuel DePaiva 5 The bike arrived quickly and all parts and hardware were in the box. The instruction booklet was in Japanese only, but my wife is Japanese so we had no problem. She read the instructions and I assembled it in just about 2 hours. The pictures in the instruction booklet were so well detailed showing where all parts and hardware went together. I think it could be assembled by someone who did not read Japanese. All the tools and hardware were numbered, in the package containing them, so it was easy to match things together. The bike is sturdy and rides quiet. The monitor works good. Only problem is that there is a connection cable for monitoring a pulse reading but no place to insert into the monitor. Not a big problem because the Distance, Speed and Timer functions all work.
