We are introducing an entirely new advanced design steel beam frame with an original & stylish body adorned with MX factory-style race graphics. The RAGE is our “Premium” 50cc version.
Engine upgrades include the Funbikes twin shoe clutch, the Funbikes easy pull starter, and for sound, performance and fantastic looks, we have a new twin-muffler performance free flow exhaust system.
This bike is stunning, a pleasure to ride and performs like a dream, and it has been awarded a much deserved “Premium” label. It may be the best Kid’s Dirt Bike ever! Just look at it!
As with our other children’s dirt bike ranges, these are not your traditional ride-on toys. They are a cut above and include steel frames, outstanding torque and real outdoor rubber tyres.
Solidly built, the bike will deal with grass, gravel, concrete and even gentle off-road use.
Suitable for both wet and dry conditions.
All Mini Rydex Bikes are not the same.
This bike will offer hours of fun in almost any children’s outdoor environment.
You should know the build quality; parts quality is essential to how much maintenance is required. This Dirt Bike has been specified for quality and reliability.
Length 123cm, Seat Height 61cm & Handlebar Height 76cm with a Max rider weight of 60kg.
Max Speed is estimated at 18mph, dependent upon terrain and rider weight.
The product’s suitability for a particular child is at the Parent’s Discretion – Buyers should also consider the rider’s Height, Weight & Skill.
CE & UKCA approved
Features Include:
Upside Down Forks
The undeniable advantages of upside-down forks include offering a more rigid set-up and handling extreme stress during stiff steering, hard braking, and other strenuous conditions. They are also less likely to bend.
Motocross Tyres
The advantages include:
- High elasticity.
- Consistent performance over time.
- Exceptional grip to control drifts and high resistance to tearing.
Suitable for all kinds of terrain.
Speed Restriction
A speed restrictor is integrated into the throttle to ensure the bike is suitable and safe for all levels of riders. Parents can easily and quickly adjust the throttle with a screwdriver to manage overall speed.
Funbikes Easy Pullstart System
Simple start with the highest grade & longest-wearing cord available. Our Funbike’s easy start mechanism means anyone can start the fun.
MX Folding Foot Pegs
Foot Pegs are one of the most significant contact points between you and the bike. MX Foot Pegs give you more bike control, so your feet sit comfortably and grip while riding. MX foot pegs also fold when the bike falls to reduce breakages.
Chromoly (Chrome Molybdenum) Steel Frame
A workhorse of the motor industry, Chromoly is a light, strong steel. When it is butted and shaped to take off excess weight, it can deliver a reasonably light frame that will last through years of hard use.
Chromoly is responsive and offers good flex while maintaining its form.
Alloy Cast Super Strong Rims
The Rage 50 wheels are upgraded to high-quality cast alloy instead of the traditional spoked. Cast alloy reduces typical spoke maintenance to a minimum, reducing the time for pre-ride safety checks, and the rims are virtually impossible to break!
They are painted in premium satin black for a great look and finish.
High-Quality Moulded Plastics With 3M Race Sticker Kit
By Combining the look & style of a full-size road bike, the new 2025 design plastics replicate an adult bike and are moulded to ensure a perfect fit and fantastic experience for our young riders.
The professionally designed graphics are manufactured from a 3M equivalent material for reduced peeling and fading.
MXR Rage Twin Muffler Performance Exhaust
With extensive testing, our development team has shown that the split to the second tip reduces back pressure in the exhaust & improves the performance.
Back pressure is reduced by beginning the Twin Muffler as a single pipe before reaching the rear of the engine and splitting into two chambers with tips. Compared to a single exhaust, we achieve that throatier sound petrol head enthusiasts crave.
Suitability & Safety Guidance
Due to evolving safety regulations and the performance of this product (up to 18mph), FunBikes now offers measurement-based suitability guidance rather than estimated age ranges. This ensures that every rider is assessed for fit and safety based on their physical size and ability, not just age.
The MXR Rage 50cc is a high-performance kids’ mini pit bike — far beyond the capabilities of standard ride-on toys. With power, off-road-ready tyres, and a robust suspension system, this model is intended for competent riders with the appropriate physical proportions and confidence to handle a 50cc output.
Fitment Measurement Guide (Seat Height & Inside Leg)
To determine whether the MXR Rage 50cc is a suitable fit, please measure the rider’s inside leg and compare to the bike’s seat height. A proper fit ensures stability, comfort, and safer operation.
- Bike Seat Height: 61cm
- Recommended Inside Leg Measurement: Between 56cm and 71cm
(Measure from the crotch to the ground, standing straight in shoes similar to what the rider would wear)
How to measure: Have the rider stand flat-footed against a wall, feet hip-width apart. Measure from the crotch to the floor. This is their inside leg — it should fall between 56cm and 71cm to comfortably reach the ground and foot pegs.
- Maximum Rider Weight: 60kg
- Handlebar Height: 76cm
- Overall Bike Dimensions:Â L123cm x W59cm x H76cm
Performance
This product is capable of speeds up to 18mph.
Due to its high-performance nature, this is not a toy, but a scaled-down dirt bike requiring coordination, confidence, and appropriate physical size, and has a manufacturer’s recommended age of 12+.
- Max Speed Performance Age Classification: 14+
- FunBikes Measurement-Based Guidance: Suitable for riders with an inside leg of 56–71cm, with appropriate height, weight, and skill level.
Important Safety Notice

All riders should:
- Wear CE/UKCA-certified safety gear (helmet, gloves, boots, protective clothing)
