Using this bike rack is easy. First, make sure your bike's weight is within the limit - up to 30 kg per bike, or 18 kg per bike for off - road travel. Use the integrated ramp to roll your bike onto the rack. Adjust the retention cradles to fit your bike frame, and secure the front and rear wheels with the straps. If you want to stow the rack, use the pull - pin to tilt the mast to the stowed position. When not in use, you can fold it for easy storage. Remember, for off - road travel, keep the load at 60% capacity. To maintain the rack, regularly check the straps for wear and tear, and make sure all the adjustable parts are working smoothly. Clean it with a mild soap and water to keep it in good condition.
