This bike is great! Got it and set it up in under an hour. Installation is straight forward. The person who rated this one star, Im pretty sure you were installing the left pedal the WRONG way. At first I went to install the left pedal and had the same problem as you! Then found out that the left pedal is threaded COUNTER-clockwise and the right pedal is threaded clockwise like normal. Make sure your turn the nut for the left pedal to the LEFT not right. Bike has great resistance and extremely quiet.

I'm a runner, but a pinched nerve in my neck had me unable to run for awhile. So, in order to stay active I decided to purchase a stationary bike. I've never owned a stationary bike and after reading previous reviews I decided upon purchasing this one.
