I've been riding my bike for around 7 weeks now, pedaling around 20 to 25 miles a day, weather permitting, except for weekends. I have to stock up on nachos and beer sometime, after all. I've gotten pretty comfortable with it and haven't had any major problems. One minor spill, but that was just to satisfy the guy at the bike store who told me there are 2 kinds of riders- those that have fallen and those that will. I guess now I'm part of that fraternity.
