GMX Motorbikes & Quad Bikes for Outdoor Riding
Please note: these are genuine petrol-powered off-road vehicles with real engines, not electric toys. They're built for supervised off-road or private property use, not registered for road use, and appropriate protective gear and adult supervision are essential.
Our GMX motorbikes collection includes real, petrol-powered dirt bikes and quad bikes for kids, ranging from a 50cc entry-level model through to a 125cc option for older, more experienced riders. GMX is a well-known name in youth off-road vehicles, and this range covers several engine sizes so you can match a bike or quad to your child's age, height and riding experience.
Each product listing includes engine specifications, maximum speed, fuel tank type and included features, helping you compare models properly. Given these are genuine motorised vehicles, we'd always recommend starting with a smaller engine size for a first bike, and stepping up as your child's confidence and ability grow.

Choosing the Right Engine Size
| Engine | From | Best suited to |
|---|---|---|
| 50cc – 60cc | $849.00 | First-time riders and younger kids just starting out on a real off-road vehicle |
| 70cc | $999.00 | Riders who've outgrown a 50cc and want a bit more power |
| 110cc – 125cc | $1,004.00 | Older, more experienced riders wanting a bigger bike or quad |
Dirt Bikes vs Quad Bikes
GMX's Moto range covers two-wheeled dirt bikes, while the Ripper-X and Beast lines are four-wheeled quad bikes. Quads generally offer a bit more stability for newer riders, while dirt bikes suit kids already comfortable balancing on two wheels. Both are genuine petrol-powered vehicles, not electric toys, so matching engine size and bike type to your child's age and experience matters more than picking on looks alone.
Frequently Asked Questions
What engine size should I start with?
For a first bike or quad, we'd generally recommend starting at 50cc–60cc and stepping up as your child's confidence and ability grow. Check the specific product listing for recommended age and height guidance.
Are these registered for road use?
No, these are off-road vehicles for supervised use on private property, not registered or intended for public roads.
What safety gear is needed?
A helmet is essential, and we'd recommend appropriate protective gear (gloves, boots, and body armour) along with adult supervision at all times.
Do you offer layby or price matching?
Yes, we offer a price match guarantee comparing total delivered cost, and traditional no-interest layby. Get in touch and we'll sort out the details.
Delivery
GMX motorbikes and quad bikes generally dispatch within 1 to 3 business days, with regional and remote addresses generally taking a little longer than metro areas.
