Haha this is still going on? I don't think anyone here is doubting you can't go fast, you just have to use way more energy to and get tired faster then if you were on a full sized bike. And if you get a bike that has multiple gears then it is going to be way easier. If you are in a congested area no **** you are going to beat traffic. If you raced a road bike against bmx for 5 miles who do you think is going to win? The person on a bmx could only keep up for so long.
