From D&D Wiki
Carrying Capacity: 300 lb.
A 19th-century invention, bicycles are energy-efficient, pedal-driven vehicles consisting of a frame and a pair of wheels. While you are riding a bicycle, your land speed increases by 5 feet for every 10 feet of base walking speed you possess; for example, if your speed is 30 feet, your speed on a bicycle is 45 feet. If you are proficient with bicycles, your land speed increases by 5 feet for every 5 feet of base walking speed you possess; for example, if your speed is 30 feet and you are proficient with bicycles, your speed on a bicycle is 60 feet. Travelling down a downhill slope with a grade of 15 degrees or more on a bicycle only costs you 1 foot of movement for every 2 feet you travel downhill. As with other vehicles, having proficiency with bicycles allows you to add your proficiency bonus to perform stunts or control a bicycle under difficult circumstances.
A bicycle is a Medium object with an AC of 10, immunity to poison and psychic damage, and 20 hit points.
