Under EEC legislation all road legal buggies and quad bikes are classed as 'Quadricycles' but due to the Quadricycle falling into PLG (Private light goods) classification there is no legal requirement to wear any safety clothing.

We strongly recommend the use of at least a certified crash helmet and eye protection for both driver and passenger when using any road legal or off road buggy, quad bike or ATV.

In the event of off road use it is also recommended that additional safety clothing is worn, this should consist of safety gloves, boots and adequate clothing covering all areas of the body.

We would like to encourage all customers to take Off-Road safety courses before getting into any Off-Road vehicles.

All machines are supplied with a Return to Base (RTB) Warranty.

In the unlikely event that you need to use the warranty, you are responsible for returning and collecting the product at your own cost. If you would prefer to fit the parts yourself or have them fitted elsewhere, then we will provide replacement parts free of charge (subject to the warranty conditions).
