Sloped track bike. I'm in college. When I've a grey beard, the 'bent.

Next one: so you walk on a shopping street, and there's a guy selling used bikes, right? There's two neat mtb's, same price, but you can only buy one. One is your size, the other perfect for a family member who wants to start riding. Which one? I was faced with that one this weekend. I went for "sleep it over" returned the next day to buy the bike for my sister, but the man was no longer there. Bummer.
