Riding a Bicycle

Operating a bicycle uses the same rules as any other vehicle, but with a few special rules:
Operating a bicycle uses Acrobatics as its drive skill.
A bicycle can only reach a maximum of street speed and doing so requires a full-round action, unless going down a significant downward slope (GM’s discretion).
The rider must use a full-round action to climb up a significant slope and can only move a maximum of half speed on such an action. • After every hour of strenuous riding, the rider must make a Fortitude Save (DC 10 +2 per additional hour) or become fatigued for 1d10 minutes per hour of riding.
It is a free action to get on or off a bicycle.
All attacks made from a bicycle suffer a –2 penalty. The rider cannot use any weapons that require both hands.
Bicycles are Small vehicles, granting a +1 bonus to Initiative, maneuver modifier, and AC.
Bicycle tires have 2 hit points each.
