    There are so many positive things about this bike: It folds and it is easy to fold even for a small woman. It fits in my car so I can get to nearby bike trails. It is comfortable to ride. I did take it to a local bike shop and I was even more impressed when they told me they, too, were impressed and it only needed tightening. Well made and sturdy. Love this bike!
