Hey all. I just wanted to get some quick advice. Is this JC Penney 3-speed worth buying? I'm basically just looking for a "back-up" bike to ride back & forth to the train station (1 mile daily) this winter, and I'd add a rack to occassionally haul groceries (less than a mile). Is this decent enough. I don't want to spend more than necessary, I have a brand new Trek hybrid that serves as my "main" bike.
