This mounting system has been purpose-designed specifically for Zone RV drawbars — not adapted from a generic solution. The entire system has been developed through detailed CAD modelling and refined through real-world testing to ensure a precise fit, long-term durability and confidence in demanding touring conditions.

Laser-cut and fully welded construction · Designed to match Zone RV drawbar geometry exactly · Stainless steel hardware · CNC-machined fish plates for a precise and secure interface. Every detail has been considered from fitment and finish through to long-term performance.

Designed as a true bolt-on solution, this system has been engineered for a straightforward and reliable installation without the need for specialised tools or complex modifications. Every aspect of the mounting system has been refined to ensure a clean fit, intuitive use and long-term practicality — so once it’s installed, it simply works.

Straightforward bolt-on installation · Standard tools only · Designed for ease of use in real-world conditions. The result integrates cleanly with your setup, remains secure under load and is simple to use day-to-day.

Loading bikes is easy when you load them one wheel at a time. It completely eliminates the need to lift the entire bike at once, making it much easier to manoeuvre and position. There’s no need for ramps or any kind of loading device — simply wheel the bike up one wheel at a time. The wheel cradles secure each wheel at four contact points, allowing you to share the weight of the bike with the carrier when loading and unloading. With the wheels secured and stabilised, it eliminates the need for any straps or tie downs.

Most products stop at either zinc plating or powder coating. At iSi, we go far beyond. Every steel component undergoes extensive surface preparation, zinc plating, and then a durable textured powder coat finish. This multi-layer system delivers long-term protection against stone chips, road salt, UV exposure and corrosive extremes you’ll encounter from deserts to coastal tracks. The powder coat acts as a tough outer shell, while the zinc beneath provides sacrificial protection. As with any coated system exposed in corrosive environments, routine cleaning and care ensure the finish continues to defend against the elements in years to come.

Add an optional Vehicle Mount System to swap the carrier between the trailer and the car quickly and easily. It’s great to base camp with the trailer and move the carrier to the car to explore areas that may not be appropriate to drag the camper or caravan through. When you have the flexibility you use it to make the most of each trip — and because we make it easy to swap, you don’t go looking for excuses to leave the bikes alone.

There’s always something nearby to explore — make the most of each and every journey.

iSi carriers employ advanced Computer Aided Design and Finite Element Modeling and Analysis tools to ensure that the optimum structural and operational design criteria are met. Then field tested over not only the harshest terrain using iSi’s fleet of dedicated off-road 4WD vehicles and caravans, but also long high speed highway travel.

Whether it be sustained high speed travel over rough washboard corrugations, rocks, soft and loose sand dunes, deep snow or running rivers — you’ll breathe easy with the knowledge that your bicycles are safe, secure and always ready for action.
