Using this Thule ProRide 598 bike rack is super easy. First, switch the bike carrier to the side of the car that's most convenient for you. It doesn't need any tools. Then, place your bike (up to 20 kg) on the rack. Use the uniquely designed frame holder and wheel tray to position the bike. When you're tightening the bike, keep an eye on the torque limiter dial. Once it signals, your bike is securely in place. Use the diagonal quick - release wheel straps on the wheel holders to firmly fix the wheels. As for maintenance, regularly check the wheel straps and the frame holder for any signs of wear. Clean the rack with a mild soap and water after use. Avoid using harsh chemicals as they may damage the black finish. Also, make sure the bike's weight doesn't exceed 20 kg to keep everything working smoothly and safely.
