There are two groups of bike riders when it comes to bike racks; those who prefer front bike racks and those who would rather have rear bike racks.
We refuse to take sides because both front and back bike racks are very useful. The one you prefer should be based on what you want to store and personal preference.
A bike rack gives you a stable foundation to hold all sorts of stuff on your bike. If the weather is good, many items can be attached directly to the rack. But for bad weather or to have the ability to hold several items, rack trunks, bags and panniers can be utilized.
A front rack offers additional space for gear if you are already loaded down in the rear. Front racks are popular among touring cyclists who carry a large amount a gear when they ride long distances.
