The New 48V Funbikes MXR1800 Electric Dirt Bike

* Product specifications are subject to change without notice and may vary from those shown. Errors and omissions excepted.

The ultimate kids’ toy, now updated for 2025 with even more powerful and faster with top speed now at 32mph! We’ve upgraded from a 1600w motor to a brushless 1800w motor, delivering more speed and performance. Plus, with an advanced controller, a stronger KMC gold chain, your child’s experience just got an incredible boost. And that’s not all—our hardware has been upgraded too! The nuts, bolts, and fixings are now made of durable stainless steel instead of chrome, ensuring long-lasting strength and quality. Get ready for the ultimate ride!

The batteries are Lithium which are much lighter than lead-acid batteries, last longer, and charge up quicker. Almost silent, this bike will offer up to 25km of fun in almost any environment.

Top speed of the previous model was 42kmh/26mph. This new upgraded version is 52kmh/32mph. With that performance, you’ll also be grateful for the high specification, light-touch front and rear hydraulic brakes with brake sensor switches.

Solidly built and simple to maintain, the bike will deal with grass, gravel, and even gentle off-roading.

Suitability & Safety Guidance

Due to evolving safety regulations and the performance of this product (up to 32mph), 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 1800w is a high-performance kids’ electric dirt 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 1800w output.

Fitment Measurement Guide (Seat Height & Inside Leg)

To determine whether the MXR 1800w 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: 68cm
• Recommended Inside Leg Measurement: Between 63cm and 78cm
  (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 63cm and 78cm to comfortably reach the ground and foot pegs.

• Maximum Rider Weight: 65kg
• Handlebar Height: 92cm
• Overall Bike Dimensions: L147cm x W64cm x H92cm

Performance

This product is capable of speeds up to 32mph and includes adjustable speed restrictor settings/dials.

• Max Speed Performance Age Classification: 14+
• FunBikes Measurement-Based Guidance: Suitable for riders with an inside leg of 63–78cm, with appropriate height, weight, and skill level.
