Wall-mounted rack and shelf combos are designed to accommodate a range of bike sizes and weights, but it’s important to check the weight capacity of the specific model you choose. For heavier bikes, make sure the rack is made from sturdy materials and has strong mounting points. Some models have adjustable arms or hooks to provide a secure fit for different bike types. If you’re unsure about the weight capacity, it’s advisable to opt for a rack specifically designed for heavy-duty use to ensure the safety of your bike and the integrity of the storage system.
