At last a safety system for quad bikes that helps protect the rider.
Quad bike accidents have claimed 45 lives and caused 17,000 injuries in the last decade mostly in the farming community. This simple device will help save lives.
how does it work?
The Quadbar (TM) is a small unobtrusive, hairpin shaped hoop mounted on the quad bike behind the rider designed to counter some of the risks associated with rollovers.
The Quadbar acts as a Passive Roll Over Protective Structure (PROPS) as opposed to the more commonly known Roll Over Protective Structures (ROPS). A typical ROPS would require a full cage and driver restraint, which are not feasible on a rider active vehicle such as a quad bike.
The Quadbar is mounted on the tow bar and is telescopically adjustable at the base. A support mount is attached to the rear rack, where the bar passes through sliding collars (bushes), which subsequently allow the suspension to move freely. The use of the tow bar is not affected by attachment of the Quadbar.
The Quadbar is designed to reduce the risk of injury caused by rollovers. Research has identified injury caused by the pinning of the rider to be of particular concern. (ref: Risk and preventive factors for fatalities in All-terrain Vehicle Accidents in New Zealand, 2009. Boaz Shulruf, Andrew Balemi). Also injuries from quadbike backflips are particularly common (ref Coronial Inquest – Melb)
The Quadbar has been designed to help prevent the operator from being pinned beneath an overturned quadbike. It is also designed to reduce crushing and pinning injuries and fatalities in cases of quadbike back flip. The Quadbar has particular application where usage is generally considered safe, and the rollover is inadvertent, such as work place environments like farms and forestry and some limited types of recreational use like touring. The Quadbar cannot be fitted to the sports type bike where the operation is generally considered risky.
The Quadbar is essentially a bolt on attachment. Currently 1 kit should fit most bikes that are fitted with a tow bar & rack. However some of the less popular bikes may require variations of the brackets.
Testing has shown that the Quadbar can be effective in preventing a quadbike from rolling more than a ¼ roll. For example during testing, the Yamaha Moto 250 completed 2 full rolls on a 20 degree or 36% slope without a Quadbar, but only ¼ of a roll with a Quadbar fitted. When the momentum is increased past the point when the Quadbar prevents more than a ¼ roll, the testing showed that the quadbike continued to roll past ½ roll, and in most cases ¾ roll to a full roll, which effectively reduces the chances of a quadbike pinning a rider. The momentum of the roll was also slowed and a space between the quadbike and the ground was maintained.
