I purchased this bike for my wife's birthday last year so we could ride together. She's a very small, tiny-boned woman of five-feet tall. We went from shop to shop and tried many different bikes, some very expensive, others ridiculously inexpensive. This bike really stood out amongst the others because of fit, features, and value.
A few comments based on our experience.
First, you get what you pay for. If you're looking for a bike you can beat on and ride excessively, you might want to look for a higher-quality, more expensive brand. This is a very good bike for the casual rider. When assembled properly, it rides very well on or off the road and is very comfortable for long periods of time. If you're a more serious rider, you'll probably want to upgrade the brakes or gears or look towards a different bike altogether. While the brakes and gears work fine, they aren't the highest quality. Also, the bike is a tad heavy, but for the price, it's fine.
Second, if you have no experience assembling bikes, or if you've only assembled a bike a few times, plunk down $25 to $40 and have a professional assemble it properly. There are alignment issues that can make or break a successful and enjoyable final assembly. I think a lot of the comments from others about wobbly wheels and sticky brakes are probably because attention wasn't paid towards proper assembly and alignment. We had our bike professionally assembled and it's been just fine! No wobbly wheels and no sticky brakes.
There's nothing wrong with this bike in its class. It's not designed to be the top of its class, but when looked at in terms of value, it's a fine bike that should last for many years, if properly maintained.
We're happy with the purchase for different reasons. For her, she's happy to have a bike. For me, it's nice to have my best gal by my side once again! :-)
