...there are people who buy them, so the people who sell them keep on making them.

I would not advise buying a bicycle from an online business, because all of the initial assembly and maintenance falls directly on your shoulders. There are a couple of big ones, like Bikes Direct, that apparently sell a lot of bicycles, and advertise fantastic deals all the time. But I think you ought to try learning the maintenance and repair using your current bicycle, before you jump into something like that.

A lot of the local shops here won't work on those bikes for you, if you end up not being able to get the bike to work well.
