Bike lockers are secure storage units designed to protect bicycles from theft and damage. They are typically made of sturdy materials like metal and come with a locking mechanism, allowing cyclists to safely store their bikes when not in use. Many bike lockers are found in public areas such as train stations, universities, and parks, making it convenient for riders to park their bikes while they go about their day. Using bike lockers encourages more people to cycle, as they provide peace of mind for bike owners. Additionally, they help keep public spaces organized by reducing clutter from parked bikes. Overall, bike lockers promote a healthier and more sustainable mode of transportation.
