An introduction
A caravan bike rack engineered for your van, not the other way around.
iSi caravan bike racks are modular by design. Mix and match drawbar mounts, support posts and rack assemblies for a precise fit on caravans, pop-tops, Expandas, camper trailers and box trailers. Clears handbrakes, jockey wheels, gas bottles and weight-distribution hitches that defeat universal racks. No compromises. When your van or tow car changes, swap components individually. You never start over.
Designed by engineers who ride. Decades of automotive, aerospace and structural engineering experience meet thousands of kilometres of remote-track field testing. Every system is CAD-modelled, FEA-analysed and precision-manufactured in Melbourne, Australia from Australian steels. One modular caravan bike rack for life. Configured for your trailer. Ready to swap to your tow car when the bikes leave the campsite.

03 — Engineered, not assembled
Form follows force.
There's a reason every iSi caravan rack looks the way it does. It's not aesthetics — it's physics. Three engineering choices, refined at the component level and proven from the Stuart Highway to the Old Telegraph Track.
01 · Bolt-On Mount
True bolt-on. No welding, no drilling.
Wide footprint spreads load across the chassis rails — without the high-stress points narrow welded or sandwich-plate mounts create. Clears handbrake, jockey wheel, gas bottles and weight-distribution clips. Trailer chassis warranty stays intact.
8 mount profiles available
02 · StrongArm Support Post
Light, rigid, millimetre-perfect.
60+ post variations — every height, every angle. Lean it forward, the carrier moves out. Vertical, it sits tight to the van. Tighter geometry, shorter lever arm, less load on the tow ball.
60+ heights & angles
03 · Modular Bike Rack
One rack. Every drawbar. Every tow car.
The same two-bike or four-bike assembly bolts to your configured drawbar — or pins off and onto your tow vehicle. Stadium-style stagger keeps the load compact and easier loading, narrow and tight to the van. Lower centre of mass. Cleaner trailer articulation.
Pin out → bolt to vehicle tow bar
04 · Complete System
Three components. Engineered as one.
Bolt-on mount, StrongArm post and modular rack — every iSi caravan rack ships as a precision-matched system. CAD-modelled. FEA-simulated. Field-proven. The lightest tow ball weight on the market. Lifetime warranty.

04 — Precision Manufacturing
Built to Evolve.
One system. Six engineered parts. Configure what fits your trailer today, swap a single piece when it changes tomorrow. The rack evolves. The investment doesn't.
01
Bolt-On Drawbar Mount
Light-gauge, high-strength Australian steel. Wide footprint spreads load across the chassis rails — no point loads, no notching. Bolt-on with 18mm and 19mm spanners. Maintains your trailer chassis warranty.
02
StrongArm Support Post
60+ variations in height and angle. Four-bolt flange mounts directly to the drawbar mount. Built-in pivot stops with five rotation positions. Light, rigid, and engineered to deliver millimetre-perfect carrier alignment.
03
Main Beam (2- or 4-bike)
Structural backbone. Stadium-style stagger for compact rack profile and zero handlebar clash. Universal — bolts to drawbar mount, swaps to a vehicle mount in under a minute, no tools required.
04
Quad Contact Wheel Cradles
Mandrel-bent hoops support each tyre at four points on the tread — never the sidewall. No clamps, bungees or straps. Independent height adjustment at every wheel. Works with everything from BMX to fat bikes and 32kg e-bikes.
05
Zero-Load Frame Support Cradles
Solid steel rod with a proprietary high-UV rubber profile co-developed with Australia's leading rubber labs. Carbon-safe. Wide, soft contact area kills the high-frequency vibration of corrugated outback tracks.
06
Cone-Point Tee-Handles
60mm crossbar, cone-point tip. Bites into the rigid upright post and refuses to slip on corrugations. Cuts a positive groove for repeat-perfect positioning. Tool-free adjustment, every time.
05 — Compatibility
Configured for hundreds of caravans & campers.
If your trailer's not on this list, it's almost certainly still compatible — our engineers spec each system individually.
06 — Built for the road, made for the track
Three things every iSi caravan bike rack does better.
01
Lightest tow ball weight delta on the market.
Lower static delta. Better dynamic loading. Centre of mass shifted back from the tow ball toward the trailer axle — the safest towing dynamics you can buy. Stays in-phase with your trailer's natural roll and pitch.
02
Pivot up in 15 seconds. Bikes still loaded.
Pull a pin. Pivot up. Done. Five rotation stop positions clear the drawbar, gas bottles and jockey wheel — even deploys the front bed on a forward-fold camper or Expanda without unloading a single bike.
03
Four bikes. Standard drawbar. Full articulation.
The only system in Australia that can do it. Stadium-stagger geometry keeps four bikes compact, narrow, and as far back as possible — preserving full trailer articulation through tight bends, steep camp-site reverses and hairpin tracks. No other rack on the market keeps the load this tight.
07 — Pricing

From-pricing assumes a standard bolt-on mount and StrongArm post configuration. Final price depends on your specific trailer's drawbar profile and bike wheel sizes — confirmed at the configure step. Cradles can be added later at the same per-cradle price; no premium for upgrading from a 3-bike to a 4-bike configuration on the same platform.
09 — Frequently asked
Caravan bike rack questions, answered.
What caravans and trailers fit an iSi drawbar bike rack?
Jayco, MDC, Titanium, Ezytrail, Austrack, Wonderland, Lifestyle, Ultimate, Track Trailer, Snowy River, Jawa, Roadstar, Bruder, Patriot and many more — including off-road touring caravans, hybrid vans, pop-tops, Expanda models, camper trailers and box trailers.
Use the Build Your Own configurator to spec the exact system for your trailer. A pre-configured library for popular caravans is launching soon.
How does iSi configure a bike rack to my specific caravan?
Every caravan has a different drawbar profile, jockey wheel position, gas bottle layout and front bed configuration. Our engineers select from a wide range of bolt-on drawbar mounts and StrongArm support posts to deliver a precise fit. The carrier itself is universal — it bolts to whichever mount and post combination we configure.
How much does an iSi caravan bike rack cost?
Single bike from $1,424. Two bike from $1,584. Three bike from $1,824. Four bike from $1,974. Final pricing varies based on drawbar configuration, mount selection and bike wheel sizes.
Will an iSi caravan bike rack affect my tow ball weight?
iSi drawbar bike racks are engineered for the lightest tow ball weight delta on the market. By moving mass back from the tow ball toward the trailer axle and using a rigid, lightweight system, towing dynamics stay safe and predictable.
Can I pivot the rack up to access my front bed or drawbar?
Yes. The carrier pivots up in 15 seconds with bikes still loaded. Built-in pivot stops with five positions clear the drawbar, gas bottles and front fold-out beds on forward-fold campers and Expanda caravans.
Can I swap the same carrier between my caravan and tow vehicle?
Yes. Add an optional Vehicle Mount System and the same carrier swaps between the trailer drawbar and your tow car in under a minute, no tools required.
Is the iSi drawbar bike rack a true bolt-on?
Yes. No drilling, no welding required. Installation is done at home with basic 18mm and 19mm spanners. All hardware is included and your trailer chassis warranty stays intact.
Can I mount an iSi bike rack on the rear of my caravan?
We do not recommend it. The rear of a caravan is subject to extreme dynamic forces that can compromise the chassis and tow point. The A-frame drawbar is the preferred mounting location for safety and stability.
How many bikes can I carry?
Two-bike rack: up to 64 kg total (32 kg per bike). Four-bike rack: up to 84 kg total (32 kg per bike). For tow ball sensitive trailers, you can split bikes between front and rear with an additional rear-mounted system — up to six bikes on a single trailer.
Are iSi caravan bike racks Australian made?
100% Australian made and 100% Australian owned. Every iSi carrier is designed and manufactured in Mitcham, Victoria, using Australian high-strength steels — and backed by a no-questions-asked lifetime warranty.
10 — One rack. Every adventure.
Ready to find your fit?
Configure your system from the drawbar up — or if you tow a popular caravan, see if we've already engineered the fit. Either way, you ride with the same Australian-manufactured, lifetime-warranty hardware.
