the first night i had my bullit built up a few years ago i rode it to my school, rode around ther, rode home- no seat though i had the wrong size post. all said and done that was a 36 pounds free ride bike, seatless, for over 8 miles.
i used to ride to my friend's house on my hydra "back in the day." it was about 3.5 miles one way. it sucked but i did it cus i wanted to ride. i will ride all day without a seat now and not even think twice about it. we may only be covering a not even a mile's worth of distance from the parking spot but it's usually a solid few hours-all day of trials along the way. if i wanted to sit down there is grass, park benches, ledges... all sorts of stuff i would ten times rather sit on than a damn bike seat- am i the only one that thinks bike seats are not the ideal sitting perch?
