<human>: I've been thinking about buying a bicycle. What are the pros and cons of bicycles?

Pros: 
 • Bicycles are environmentally friendly, as they require less energy than cars or motorcycles to move around.
 • They provide an excellent way to get exercise and stay healthy.
 • Bicycles can be used for commuting, leisure activities, and errands.
 • Bicycles have fewer safety risks compared to other forms of transportation.
 • They're generally cheaper to maintain and repair than other vehicles.

Cons:
 • Bicycles are more difficult to ride in hilly terrain or on rough roads.
 • They require more physical strength and agility to operate safely.
 • Bicycles can be harder to park and store when not in use.
 • They may not be suitable for long distance travel due to their limited carrying capacity.
