Roof boxes can be safe under normal conditions but pose risks in collisions due to their high placement, which affects vehicle stability and increases danger. Most roof boxes lack high-speed crash testing, leaving their real safety uncertain. Towbar-mounted cargo boxes like IXTAbox, mounted low and crash-tested under extreme conditions, offer a much safer, more secure alternative for transporting your gear.

Not all storage boxes offer the same level of safety. IXTAbox is crash-tested under extreme conditions, staying securely attached even with heavy gear or bikes. Mounted low on your car’s towbar, it provides better stability, reduces risk in accidents, and protects other road users — making it the safest rear cargo box available. Integrated LED safety lights further enhance visibility and peace of mind on every trip.

Roof boxes offer good weather resistance but aren’t fully waterproof, which can allow moisture to seep in during heavy rain or long trips. To keep your gear dry, use waterproof bags and maintain seals regularly. IXTAbox, built with corrosion-resistant aluminum and stainless steel, provides superior protection against harsh weather, ensuring your cargo stays safe and dry no matter the conditions.

Wondering if you can carry bikes on a cargo box?
With IXTAbox, the answer is yes! Store helmets and accessories inside, fit foldable bikes securely, or mount larger bikes on the box lid using built-in rails. It’s a versatile, safe, and easy solution for all your biking adventures.

If you own a large SUV or electric vehicle, towbar mounted cargo boxes, like IXTAbox, offer the perfect extra storage solution. Compatible with many popular models including Tesla Model X and Audi Q8 e-tron, IXTAbox provides ample space for bulky gear, easy waist-height loading, aerodynamic efficiency to save fuel or extend EV range, and integrated safety lights for road visibility.

Electric vehicle owners need smart storage solutions that don’t compromise driving range or comfort. Traditional roof boxes increase drag and noise, reducing your EV’s efficiency. Towbar mounted cargo boxes, like IXTAbox, provide a sleek, aerodynamic alternative — reducing drag, extending range, lowering noise, and offering easy waist-height access. Perfect for EV drivers who want to carry more without sacrificing performance.
