This cycling bike had some good reviews on Amazon.com so I decided to try it. Great shipping with Amazon Prime and fantastically easy to assemble when it arrived. Rode for a day but could not overcome the uneasy feeling of the handle bars being loose and shakey. I shimmed them with paper by day two and even then there was movement. I also noticed that the seat rocked when seated. So at a standing pedal the handle bar issue irked me and made me feel unsteady on the bike and when seated the seat rocked, not a comfortable set of circumstances for me. I hated to return this bike because it had so many nice features but ultimately I needed a bike that made me feel rock solid, without wobbling and rocking back and forth. Amazon handled my return, so far, in a efficient way. I just watched the UPS driver pick up the bike for return, very easy and not stressful on my part. Am now in search of another bike.
