Leisure bicycles typically feature upright handlebars, wide seats, and stable geometry, providing a comfortable riding position. The frames are often made of durable but lightweight materials like aluminum or steel, ensuring ease of handling and portability. The tires are typically wider, with smooth tread patterns, for better grip and stability on urban streets and paths. In leisure bicycles, the bottom bracket is often designed for durability and low maintenance. It must be able to withstand the constant torque and stress applied by the rider during pedaling, while also providing a smooth and reliable connection between the crankset and the frame.

Road bicycles are known for lightweight frames, narrow tires, and aerodynamic design. Carbon fiber or titanium frames offer strength and durability with minimal weight. Narrow tires prioritize speed, while adjustable handlebars and seats cater to rider preferences. Crucial to road bikes are the cranks, typically made of titanium or carbon fiber and attached to the bottom bracket, connecting pedals to the drivetrain. Crank arm length and design influence gearing and riding feel, with shorter cranks for direct pedaling and longer for added leverage.

Mountain bicycles are designed for adventure, with sturdy frames, suspension systems, and wide tires for stability. Key features include disc brakes for powerful stopping and adjustable gearing for climbing steep slopes. Essential accessories enhance the riding experience. Helmets protect against falls, while water bottles keep riders hydrated. Repair tools, such as multi-tools and spare tubes, are crucial for unexpected breakdowns. Comfort is essential, with padded seats and grips providing added support. These features and accessories ensure a safe, enjoyable ride on any terrain.
