Using your Saris bike rack is easy. First, find a suitable location to install it, like on your car or in your garage. Then, follow the instructions in the box to assemble it. Make sure all parts are tightly connected. When using it to carry a bike, place the bike on the rack carefully and secure it properly. As for maintenance, keep the rack clean by wiping it down regularly. Check for any loose parts after each use and tighten them if needed. Avoid exposing the rack to extreme weather conditions for long periods. If the box has minor wear, it won't affect the rack's performance, but you can still keep it in a dry place to prevent further damage.
