Glad I found this site. This is Mark, I'm 54 years old and currently living in bicycle heaven, Arizona. I haven't riden a bike since 2000 and would like to get back into the sport. I'm not sure what type of bike to get at this point. Can't see myself doing any competition, but I can see myself using a bike in daily commuting, light grocercy shopping, weekend rides with friends, and hopefully work into some touring. The Schwinn World Street model looks like it might work, and I read some reviews on the Trek 520. Does anyone out there have any knowledge on these two bikes or possibly others I should look at? My budget won't allow me much past the $1000 to $1200 range.
