Bike racks engineered for every adventurer.

A tow ball bike rack mounts onto the 50mm square hitch receiver of a vehicle tow bar. The iSi tow ball bike rack is the most compact carrier on the market — zero side-to-side overhang, always within the vehicle envelope, while still delivering maximum departure clearance off-road. True pivoting all the way down to the ground comes standard, so side-opening rear doors, vertical tailgates and barn doors all clear the rack with bikes still loaded. Loading and unloading is fast and tool-free.

Every iSi rack is manufactured from Australian mild and stainless steels, zinc primed and finished in textured Dulux powder coat, and backed by a lifetime warranty.

The iSi Two Bike Rack carrier weighs 14.15kg and is rated to 64kg total. The Four Bike Rack carrier weighs 25.75kg and is rated to 84kg total. Both carry up to 32kg per bike, comfortably handling e-bikes.

Both share the same Quad Contact Wheel Cradle system and the same modular interchangeability between vehicle and caravan platforms. The two bike is the lighter, lower-profile option. The four bike handles families and groups.

Pricing starts at $1,299 AUD for the two bike vehicle rack and $1,689 AUD for the four bike vehicle rack. Caravan configurations start at $1,584 (two bike) and $1,974 (four bike).

All prices include the modular Australian-manufactured carrier system and a lifetime warranty. Final price depends on departure angle, beam length, pivot base profile or H-Mount/StrongArm setup, and accessories selected in the configurator.

iSi racks accept wheelbases up to 1600mm and tyre widths up to 5.1 inches. This covers road bikes, hybrids, mountain bikes, gravel bikes, e-bikes and most fat bikes. Each bike is rated to 32kg.

Wheel cradle reducers are available at $34 per pair for smaller wheel diameters or narrower tyres.

Every rack uses Australian mild and stainless steels, is zinc primed and finished in textured Dulux powder coat, salt spray tested, and backed by a no-questions-asked lifetime warranty.

Yes. That is the iSi modular advantage. The Two Bike or Four Bike carrier is identical across platforms. Pair it with a vehicle tow ball mount for your 4WD, ute or EV, and a drawbar mount system for your caravan.

The carrier transfers between platforms in under one minute, no tools required. One rack. Two platforms.

The carrier is identical and interchanges between platforms. The mount differs.

Vehicle bike racks use a tow ball pivot base that fits a standard 50mm square hitch receiver on a car, 4WD, ute, SUV or EV. Caravan bike racks use H-Mounts and StrongArm support posts that bolt to the caravan drawbar A-frame, configured to the specific drawbar geometry of each van.
