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 which makes 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. Moreover, with the wheels secured and stabilised, it eliminates the need for any straps or tie downs for the quickest bike loading and unloading.

Nice and tight to the rear of the vehicle, rock solid and 15 seconds to access to the rear cargo compartment. Easy.
The iSi 4x4x2 bicycle carrier pivots down all the way right from the tow bar for the ultimate in quick and convenient access to the rear of the vehicle. Completely eliminates the hassles of bicycle carriers that just tilt but obstruct the opening of side hinged rear doors. When the door’s open, drawers and fridge slide will open fully for drivers of vehicles like the Toyota Prado, Jeep Wrangler, Mitsubishi Pajero, Nissan Patrol and many more.

There’s more to travelling with bicycles than simply loading them onto a car and transporting to a destination. Eliminate hassle and never go looking for excuses.

Designed with the sole purpose of keeping your bicycle upright – gently. A world of engineering has gone into the iSi Frame Support Cradle to deliver the world’s leading bicycle retention system.
To specifically address operation over harsh corrugations at speed, additional mass added to the contact area to eliminate high frequency vibrations.

Working in conjunction with iSi wheel support cradles that support and stabilise each wheel, iSi comprehensively eliminated the high-load issues that continue to plague other platform carriers that require high strap-down loads. Moreover, by gently supporting the frame, iSi eliminates the bearing fretting and static wear issues of wheel-only retention carriers experience. For high UV resistance, vibration isolation and a wide and soft contact, Australia’s leading rubber laboratories collaborated with iSi to design and extrude our own special section soft, supple and super durable rubber profile that is head and shoulders superior to every other bicycle carrier product on the planet. iSi’s thick, wide and flat contact area, acts as a highly effective vibration isolator and eliminates the abrasive issues of inferior round section pads.

With next to zero load, the iSi frame supports eliminate wheel and head stem fretting issues and deliver the ultimate protection for titanium, thin wall alloy and the most fragile of carbon fibre bicycle frames.

The best possible departure clearance is vital to protect the bikes from below but more importantly, positioned so that the bikes are protected from above and sides as well. 100% of the driver’s concentration can then be focused on the track ahead.

However, there’s more to departure clearance than simply raising the bikes up high. With the shortest possible protrusion out of the tow bar, the whole assembly is protected when dragging the rear over big rocks and deep gullies as well as those surprise high speed dips.

Moreover by eliminating tow bar protrusions that dig into the track, the car can drive back down or be recovered out of a steep river crossing without digging into the track.

Relax and concentrate on the track and obstacles ahead without worrying about dragging or smashing the bikes behind.

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.

Scientifically, this finish is proven to outperform. 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.

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 in a highly cost effective manner.

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.

Without doubt, iSi carriers deliver the ultimate in bicycle carrying performance and total peace of mind – regardless of the severity of the terrain.

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.

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.

Complete freedom to position adjacent bicycles regardless of individual wheelbase.

The unique iSi clever design wheel cradles cover a wide range of position adjustment that extends from offset one way, precisely centred through to offset the other way. In other words, two wheels may be positioned exactly side by side for zero side to side offset of the bicycles. This completely solves the problems created by other bicycle carriers that can’t be centred and leave no option but to push one bicycle to the left and the other to the right.

A neat and centred load that is as slim as possible delivers the most stable and safest dynamics for both highway and off-road travel.

Strong, secure and manufactured from 100% Australian high-strength plate steel and tube, the iSi Pivot-Base is designed to breeze over the harshest terrain.

With the simple push on the iSi Pozi-Lock latch, the main beam section pivots down for easy access to the rear of the vehicle. Moreover, by lowering the complete assembly, the bicycles remain secured for maximum convenience.

When done, raise the beam to the upright position and the iSi Pozi-Lock latch does the job of securing the load. Slip the security pin in and you’re ready again to hit the road and tracks.

For all combinations of bicycle sizes, each wheel support cradle delivers vertical adjustment in addition to horizontal with a vertical high and low setting.
This unique iSi feature eliminates the hassles of interference between bicycles that occur with other horizontal or vertical bicycle carriers.
For example, if a handlebar clashes with the adjacent bicycle saddle, swap the wheel cradle vertical settings to position the handlebar up and over or just below the adjacent saddle. Easy. No other bicycle carrier in the world has this clever feature available.
Adjust the vertical height of each wheel at each end of each bicycle. Sounds like a mouthful but an incredibly powerful feature to eliminate pesky clashes between bicycles.

One of the important features unique to the iSi Extreme Duty Bicycle Carrier is the ability to position the bicycles side by side for absolutely zero sideways offset and the narrowest silhouette possible.

Absolutely vital when not only trickling through tight tracks, but also when squeezed through traffic and between parked cars.

The iSi bicycle carrier comprehensively solves the age old side overhang problem that plagues every other platform carrier in the world.

Relax and concentrate on the track and road ahead, safe with the knowledge that the bikes do not poke out past the sides of the car.
