Clic Dual Wheels

With quad bike safety, or should we say lack of it, regularly hitting the headlines, Brent Lilley decided to investigate a safety alternative in the form of dual wheels and was pleasantly surprised by their effectiveness.

There has been a lot of talk in the media recently about the dangers of quad bikes on farms. In my opinion some is justified and some not; but the fact remains that there are too many serious (some fatal) quad bike accidents on farms in New Zealand that could be prevented.

While there has been a lot of hype around making helmets compulsory and ongoing discussions around fitting roll bars to quads, there is another solution which hasn’t had nearly as much publicity, yet is a very simple and practical alternative. Clic Dual Wheels are a set of purpose-built dual wheels that, as the name suggests, simply click onto a quad bike (or other farm machine) and provide increased stability on hills.

To experience these duals for myself, I headed down to Katikati in the Bay of Plenty to visit Mike Darling, who owns a set.

Mike has a contract spraying business and for the past 12-months has been using the Clic Duals on his Polaris Quad to enable him to spray on all sorts of terrain. A mad keen hunter, Mike also uses the Clic Duals in fairly remote and challenging areas all over the country.

The motivation to fit his bike with duals first came about after rolling his bike on a hunting trip in the Southern Alps. He says that since fitting them, several of his hunting companions have also kitted their bikes with duals, just to keep up.

The Test

For the test, I had Andy Guet from Clic Dual Wheel Systems there to answer my questions, as well as a few of Mike’s mates.

We took Mike’s quad down to a steep little gully on his property, where Mike was pretty keen to test the bike to its limits in order to demonstrate the effectiveness of the duals. He was clearly in his element criss-crossing the slope on the bike which never once looked like rolling over.

To get an idea of the difference the duals made to the stability, we parked the quad on a slope and tried rolling it over by hand, which proved impossible. We even had difficultly just getting the upper side wheel off the ground. Next we took a dual off and parked the bike in the same spot, and with very little effort from Mike the bike flipped up on to its side straight away; luckily there were a few of us around to stop the bike rolling to the bottom of the gully.

Removing and attaching Clic Duals

When Andy removed the dual from the bike, I actually had to ask him to put it back on again and take it off slowly, as the process was so quick that I missed it the first time.

To release the duals, two handles inside the hub of the dual are turned into the unlock position, releasing the locking pins. The wheel is then turned about an 1/8th of a turn forwards to remove the pins from the locking slots and the dual is off the bike – that simple. When it comes to putting the duals back on, the process is just as simple – a locator pin in the centre lines everything up in the right position, then with a turn backwards the four pins lock into the slotted holes on the mounting plate and the locking pins click into place, which locks the dual into the bike.


Something I was a little concerned about was the effect the duals would have on the bike’s turning circle and general handling. I was pleasantly surprised to find that the duals have little effect, as they are slightly smaller than the quad bike tyres and therefore only just touch the ground.

Mike did mention however, that the duals make it tougher to turn on hard surfaces such as asphalt or concrete. But because they can be taken on and off so easily, it’s not really an issue.

Construction and set up

The secret behind the speed of the removal and attachment of the duals is the unique mounting plate used to secure them to the original studs on the bike.

To set your bike up to be compatible with the duals, all you need to do is replace the original wheel nuts with longer threaded nuts that the mounting plate can then be bolted to, then bolt another disc to this mounting plate. This disc has a hole in the centre for the locator pin and four slotted holes around the outside which the duals lock into. This set up only needs to be bolted onto the bike once, as it’s quite slim and unobtrusive.

When the duals are off, the mounting plate is barely noticeable as it’s only marginally wider than the original wheel rim.

The dual has a standard centre that can be bolted onto any sized rim. This centre has a locator pin in the middle and four pins around the outside that fit into the slotted holes on the mounting plate, to hold the dual in place. Two further spring-loaded locking pins lock everything in place, preventing the dual from turning and falling of the bike.

All the components are made out of a high quality steel alloy and the fact that they can be fitted to any-size rim makes them very versatile.

About Clic Dual Wheel Systems Ltd

Clic Dual Wheels are manufactured in Switzerland by GS Schaad Ltd, which has been specialising in the manufacture of duals for tractors and heavy machinery since 1972. The company takes pride in its reputation for high quality and precision engineering. Schaad has become the leading manufacturer of duals for all types of vehicles worldwide including the revolutionary Clic Duals, which have been sold around the globe since 2002.

Clic Duals are marketed in New Zealand by Andy Guet, who is originally from Switzerland but was lured out here by his Kiwi-born wife. His company Clic Dual Wheel Systems Ltd is now the sole importer of Clic Duals for machinery up to six-tonnes.


As someone who had never had anything to do with quad bike duals but had fitted plenty of tractors with them in the past, I came away from the day very impressed by this concept and product.

The standout difference between Clic Duals and other products I’ve fitted to tractors is how quick and easy it is to attach and remove them. The versatility of being able to bolt the centre onto any size wheel rim also means these duals can be fitted to a range of machines; Andy has customers who have fitted them to ride-on mowers, bobcats and utes.

Mike Darling and his mates who were there on the day had nothing but praise for the duals and for someone who’s tested them in some pretty serious situations, he’s a very reliable advocate for this product.

From a safety point of view, preventive measures are always better than learning from your mistakes. So instead of taking a gamble on the slopes, it’d be worth your while to give Andy a call and try a set of Clic Duals.
