The towbar trunk is on the rise: is it expensive?

July 7, 2025

Innovative luggage box

Going on a car vacation this summer, but don’t know where to put all your luggage? Then the Aero towbar box might be the perfect solution. This innovative luggage box, mounted on a bike rack behind your car, combines extra cargo space while maintaining driving range. What’s more, in some cases it even improves the streamline of your car, boosting your efficiency – just like the long tail of a Le Mans racer.

Aerodynamics as an asset

What distinguishes the Aero tow box from, say, a roof box, is its position behind the car. This keeps air resistance down and allows your electric car to maintain its range. With a roof box, consumption often increases noticeably, but with a towbar box, that effect is minimal or even positive. The clever design contributes to aerodynamics, making the trunk perfect for those who want to drive long distances with an EV without having to charge unnecessarily often.

Capacity: 310 liters of extra luggage

The Aero towbar trunk offers 310 liters of additional luggage space. With this, you sometimes almost double the capacity of a compact trunk. The load capacity is 45 kilograms and the trunk itself weighs 13 kilograms. With dimensions of 130 by 60 by 59 centimeters (external) and 124 by 56 by 54 centimeters (internal), it can hold large bags, suitcases or even camping equipment.

Another advantage is the practical design: the trunk is easy to open and tilts with the bike carrier. This allows you to maintain access to the regular trunk space, even with the tow-bar mounted. Ideal on the road: quickly grab something from the car without having to dismantle everything. Combinable with the 2- or 3-bike carrier with tilt platform, this Renault tow box increases your cargo volume by 310 liters. You can easily open the aero cargo box and maintain access to the boot.

What do you need?

Important detail: you do not mount the towbar trunk directly on the tow bar, but on a bike carrier. Without a tow bar and bike carrier, the trunk itself is of little use. The sum can add up: a tow bar costs on average about 900 euros, a decent bike carrier 550 euros and the tow-bar itself about 625 euros. Including installation and accessories, this quickly puts the price at around 2,000 euros.

Conclusion: indispensable for EV vacations?

With the Aero towbar trunk, you can turn your electric car into a full-fledged travel car in no time. Thanks to its clever design and extra luggage space, you can take everything you need with you without having to constantly search for charging stations on the road. For those who take an EV on vacation and lack space, it’s an investment that quickly pays for itself in comfort and convenience.
