The iSi drawbar mounting system comprises of a number of bolt-on mount models and sizes to suit the huge variety of trailer drawbar configurations. It forms an incredibly strong and rigid base to then bolt any of the iSi StrongArm support post models to. Just as there are many different drawbar mount models, there are also many different support posts to choose from. Mix and match for the ideal combination – no compromises.
iSi Extreme Duty drawbar mounts deliver a very wide and very long footprint in order to spread the load and eliminate pressure hot spots on the drawbar chassis rails. This eliminates the high point loads that result from narrow welded or bolted mounts. As a true off-road system you will never find sandwich plate mounts on any iSi products.
Moreover, iSi Extreme Duty mounts are designed to clear drawbar mounted items such as the hand brake, jockey wheel and is compatible with most weight distribution system, stone guards, storage boxes and gas bottles. iSi has them covered.
The mounting system includes every nut, bolt and bracket for an easy home installation backed with a comprehensive installation guide to make the job easy and enjoyable. All of the mounts supplied by iSi are bolt on and can be fitted at home with an 18mm and 19mm spanner or ring spanner. This is the ultimate caravan bike rack.

A light footprint that won’t damage or notch the drawbar arms yet delivers a rigid and super-strong bolt-on mount platform for the rest of the carrier. Mix and match for the perfect fit on any drawbar.

Just as there are many different drawbar mount models, there are also many different support posts to choose from. Mix and match for the ideal combination – no compromises. iSi StrongArm support posts are manufactured with matching four-bolt flanges to mount directly to the selected iSi bolt-on drawbar mount model. With a huge variety of support post models that vary in height and angle, it’s a simple procedure to select the ideal mount and bolt-on drawbar mount. As the post angle leans further forward, the position of the carrier moves forward as well. Conversely, as the post angle moves back towards the vertical, the carrier moves back as well. A very clever and straight forward system to deliver millimetre-perfect positioning of bicycles.

A range of light and highly rigid posts bolted to the drawbar mount to then pin the carrier to. Really easy pivot up for easy access.

Simply pull the lower pivot pin and insert into the relevant rotation stop. Then pivot up. That’s it. Quick, easy and oh so convenient. That’s what makes this the best caravan bike rack on the market.
In order to deliver the best clearance possible, the pivot function is configured at the nose of the carrier. This has the whole assembly pivot up and forwards to move the load away from the front of the van and up to help clear the rear of the tow car when still attached.
The rotation crown has five stop positions to hold the carrier anywhere from vertical through to rotated all the way over. Regardless of the caravan, there’s a rotated position to suit.

Easy and quick access to the front box, gas bottles and to deploy the front bed on a forward fold camper or caravan. 15 seconds – or quicker if it’s raining.

A light static tow ball weight delta is one part of delivering excellent towing dynamics, however as soon as the trailer starts moving, dynamic loads become far more important.
One of the key iSi benefits is the drawbar mount bike rack assembly and bicycle load is moved as far away from the tow ball as possible in order to move mass off the tow ball and back towards the axle. Moreover, as a rigid system, tight offset off the caravan or camper body can be maintained for the best result possible.

Clever design and 100% Australian steel means that iSi drawbar mounts are some of the lightest in the industry and more importantly, head and shoulders the most rigid available.

The iSi Bicycle Carrier comprehensively solves the age old problem of carrying bicycles on the drawbar whilst continuing to deliver excellent trailer articulation as you back into tight camp sites.
Through a number of unique design features such as the staggered design, the iSi Bicycle Carrier delivers the most compact load so that the entire load is as narrow and as far back as possible to achieve the perfect caravan bike rack solution.
This allows the iSi drawbar mount bike rack to deliver excellent trailer articulation on caravans and camper trailers that have incredibly short drawbars. Our experienced staff are always at the ready to advise on each particular caravan and camper trailer.

One of the key benefits of the iSi drawbar mount system is the ability to add mounts and carriers to either end of a camper trailer or caravan for up to six bicycles on a trailer. It is not just a caravan bike rack.
For tow ball weight sensitive trailers, move one or two bicycles from the front to the rear and get things back in perfect balance.

Add bicycles to the front and rear for the perfect trailer balance and lightest tow ball weight possible. *Engineered rear towbar is required*

The position, height and rigidity of the loaded carrier can have a huge affect upon the towing dynamics as well as the handling performance of the tow vehicle. The ideal solution positions the Centre Of Mass vertically close to the trailer roll-centre and longitudinally back away from the tow ball for the lightest weight delta possible – all in a highly rigid drawbar mount bike rack system to keep the load in-phase with the trailer dynamics. Ideal for modern Electronic Stability Control systems that operate to prevent loss of control in an inherently stable trailer rather than attempting to keep an unstable trailer under control with noting in reserve.

Relax and tow in safety and with confidence with predictable handling in the event of an emergency swerving manoeuvre.

Not just a Caravan bike rack. 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 and 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 so make the most of each and every journey.
