Everyone loves a great rack, but sometimes they just hang out a bit too far...
Most manufacturers can and do warrant their products as compliant with Australian Design Rules (ADRs), but compatibility of a rack with a specific vehicle is the owner's responsibility.
Australian Design Rule 43/04 - Vehicle Configuration and Dimensions requires that the total rear projection, measured from your vehicle's rear axle centre, must not exceed 60% of your vehicle's wheelbase. This is important for the safety of other road users when your vehicle is manoeuvring.
Vertical racks are a great solution for shuttling bikes on trail roads, however, they will overhang beyond legal limits on most passenger vehicles.
In most cases, platform racks are only suitable for a single bike & in many cases, platform racks are not legal even with one bike.
Here's a comparison of last year's top 10 selling vehicles in Australia when fitted with typical market leading hitch-mounted racks
When vehicle manufacturers specify roof load capacities, they also specify limits on the height of loads to ensure a safe level of vehicle stability is maintained.
Allowing for the typical mass and load centres of the racks, carriers and bikes, these vehicles are likely to be limited to a maximum of 2 conventional mountain bikes...
(Vehicle roof capacities may be further reduced if travelling off-road)
