It does depend on what one defines as "riding a bicycle." At a moderate pace from point A to point B, or simply a lap around the neighborhood is one thing. Technical single tracks, grueling climbs, steep and slippery downhills, racing, maintenance and tuning, trials, jumps, drafting... Math is just splitting the bill with your friends, seeing if you have enough cash for a hotdog AND a coke, or counting how many months of savings in order to buy that 5000$ bicycle.
