*Braking skills: as we all know the principle of hard braking is first stopping the rear brake then the front brake. But in
case of an emergency, everyone will stop all together. If the braking distance is appropriate, the bike can stop securely; if
the slowdown is too fast, people often would be thrown forward and in order to prevent this danger, the best way is
intermittent braking, and meanwhile the hip is pushed backward. In rainy days, increase the braking distance due in safety
and reduce the speed.
