Using this rack is easy. First, adjust the rack legs to fit your 24” or 26” wheel fat bike with disc brakes. Make sure it's securely attached. You can then attach your panniers or other compatible bags to the rack. The side bar provides a lower attachment point, so you can arrange your cargo in the most efficient way. When it comes to maintenance, keep the rack clean and dry. Regularly check the tightness of the attachment points to ensure safety. Also, note that this rack won't work with fat bike frames that have an asymmetric rearstay design, so double - check your bike's frame before using it.
