MOXZILLA Adjustable Passenger Backrest

Bike top racks are usually made of sturdy materials such as aluminum or steel to ensure durability and strength. They often feature padded or rubberized components to protect both the bike and the vehicle from scratches and damage during transportation. Bike top racks can vary in capacity, ranging from carrying one to several bicycles depending on the specific model and design. Some racks are designed to accommodate multiple bikes side by side, while others may be more compact and suitable for transporting a single bike.
