1 If you are most concerned about security, choose a car carrier that is lockable and has a hard side. The downside of course is that they are expensive, and in addition, they are often stored cumbersomely when not in use.
2 If you want to keep your budget within a certain range, choose a soft, lightweight duffel bag. When it is convenient to store, it can be rolled up and stuffed into a small storage space. Shipping bags with thicker UV materials and a sturdy zipper will last longer. If you want it to be waterproof, look for bags made of specific materials.
3 Pay attention to wind resistance, which will affect the mileage of the gasoline and the noise on the highway. The luggage rack is usually more aerodynamic than the bag and does not flutter like a bag. When driving, the rear bracket of the car attached to the SUV or the rear luggage rack of the truck has no air resistance.
4 Make sure the frame length is right for your vehicle. If it is too long, the rear hatch will touch it when it is lifted. And if the roof rack exceeds the front windshield, it may block the updraft and affect the steering.
5 Consider the color. Light-colored frames are usually more expensive because they absorb less heat than black frames.
6 Prompt: the roof rack is probably the best choice for a fixed tandem bicycle.
Do not select a frame or bracket that exceeds the weight limit of the vehicle. Before purchasing a roof rack, check the maximum allowable weight on the roof to ensure that the equipment is not towed beyond the vehicle’s payload limit. Before viewing a large hook unit, check its traction capabilities.
