Why Quadbar?

ATV/ Quadbike roll bar or roll over protective structures (ROPS)

The Quadbar is a small unobtrusive, structure mounted on the quad bike (ATV) behind the rider, designed to counter some of the risks associated with rollovers. The Quadbar acts as a Crush Protection Device (CPD) 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 quadbike.

The ‘Quadbar Flexi’ TM has a flexible joint that allows the bar to flex rearwards in the inadvertent event of contact with an overhead obstacle. The joint also facilitates some sideways flexibility before the joint locks and then becomes more of a traditional CPD meeting or ROPS. Ingeniously, in the event of a rearwards overturn there is negligible movement form the flexi joint. US Pat. Appln. No. 16/392,485 Australian Pat. Appln. No. 2019202833

 Research has identified injury caused by the pinning of the rider to be of particular concern. "Being pinned to the ground by the quad made up 70% of farm quad fatalities" according to the University of New South Wales TARS research report 2016*. The Quadbar is a device designed to reduce the risk of injury caused by quadbike rollovers.

 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 the event of a 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.
