Using the Ampd Bros Stubbie Rear Cargo Rack is easy. First, use the included mounting bolts to attach the rack securely to your Stubbie Electric Bike. Make sure it is tightly fixed to avoid any wobbling. When loading items, keep the weight evenly distributed and don't exceed the recommended maximum loading of 25kg. This will help maintain the balance of your bike and ensure safe riding. For maintenance, regularly check the mounting bolts to ensure they are tight. If the rack gets dirty, you can clean it with a mild soap and water solution. Avoid using abrasive cleaners as they may damage the Matte Black finish.
