4. Setup (Installation)
Follow these steps to install your Vipdrive Bicycle Cargo Rack:
- Attach the Main Rack to the Seat Post:
Secure the quick-release clamp of the main rack to your bicycle's seat post. Ensure the clamp is tightened firmly to prevent rotation or slippage. The rack should be level or slightly angled upwards towards the rear. - Install Adjustable Support Rods:
Connect the adjustable support rods from the main rack to the designated mounting points on your bicycle's rear frame. Adjust the length of the rods to ensure the rack is stable and level. Tighten all bolts securely. - Attach Side Protection Bars:
Mount the two side protection bars to the main rack. These bars help prevent luggage from interfering with the rear wheel spokes. Ensure they are firmly attached. - Install Rear Reflector:
Attach the provided rear reflector to the designated mounting point at the back of the main rack. This enhances visibility, especially during night rides. - Final Check:
Before riding, double-check all bolts, nuts, and quick-release mechanisms to ensure they are fully tightened. Gently shake the rack to confirm it is stable and does not wobble.

5. Operating (Usage)
The Vipdrive Bicycle Cargo Rack is designed for versatile use:
- Loading Cargo: Place your items on the main platform of the rack. Use the included elastic cord or other straps (not included) to secure your cargo firmly to prevent shifting or falling during transit.
- Adjustability: The rack features retractable armrests and an adjustable frame body to accommodate various bicycle types and cargo sizes. Adjust these components as needed to ensure a secure fit and optimal weight distribution.
- Side Protection: The integrated side protection bars safeguard your luggage from rubbing against the bicycle's rear wheel, preventing damage to both your cargo and the wheel.
- Weight Limit: Always adhere to the maximum load capacity of 50 kg (110 lbs). Exceeding this limit can compromise safety and product integrity.

6. Maintenance
To ensure the longevity and optimal performance of your cargo rack, follow these maintenance guidelines:
- Cleaning: Wipe the rack with a damp cloth to remove dirt and grime. For stubborn dirt, use a mild soap solution and rinse thoroughly. Avoid abrasive cleaners that could damage the finish.
- Fastener Checks: Regularly inspect all bolts, nuts, and quick-release mechanisms for tightness. Re-tighten any loose fasteners to prevent accidents.
- Corrosion Prevention: Although made of corrosion-resistant aluminum alloy, prolonged exposure to harsh weather conditions can affect its appearance. Store your bicycle and rack in a dry environment when not in use.
- Damage Inspection: Periodically check the rack for any signs of damage, such as bends, cracks, or excessive wear. If significant damage is found, discontinue use and replace the rack.

7. Troubleshooting
If you encounter issues with your Vipdrive Bicycle Cargo Rack, refer to the following:
- Rack is Wobbly or Loose:
Ensure all mounting bolts, especially those connecting the support rods to the bike frame and the quick-release clamp to the seat post, are tightened securely. Re-adjust the support rods if necessary to achieve a stable fit. - Rack Does Not Fit My Bike:
Verify your bicycle's wheel size (24-29 inches) and seat tube diameter (less than 1.26 inches). The rack's adjustability accommodates a range of sizes, but extreme variations may not be compatible. - Cargo is Not Secure:
Always use appropriate straps or the included elastic cord to firmly secure your cargo to the rack. Ensure the weight is evenly distributed and within the 50 kg (110 lbs) limit. - Rack Appears Damaged After Use:
Inspect the rack for signs of overloading or improper installation. If the rack has been subjected to loads exceeding its capacity, structural integrity may be compromised. Discontinue use if damage is observed.
