But who keep an eye on that? In Spain the speed limit of any bike is 45 km/h (around 28 mph), and when we are in the road with bigger limits to other vehicles, outside the city normally, we are faster than that (if we can) and nobody bothers. Even the police won't tell you anything unless you're doing something dangerous.
