This is a rally nice piece of equipment. What I like about it is you can watch TV & pedal mindlessly. It is quiet and before your know it you have done a good bit of exercise. The actual machine is made nice but the instructions include some errors. You can tell a non English speaking person wrote them. There is nothing to assemble. I recently had knee surgery & this is a perfect way to get extra exercise on the knees & legs. I have lots of other exerercise equipment that is bigger & more expensive but I actually use this mini bike almost every day for at least 1 hour while I am watching TV.
