The New 48V Funbikes MXR1800 Electric Dirt Bike The ultimate kids' toy, now updated for 2025 with even more powerful and faster with top speed now at 32mph!

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!
Upside Down Hydraulic Front ForksThe sturdy yet lightweight upside-down hydraulic forks deliver exceptional performance, keeping the front wheel securely planted even when pushed to the limit. They offer a smooth, responsive feel, ensuring a confident and thrilling ride. 
XOD Hydraulic Brakes & Vented Wavy Brake DiscsThe high-performance XOD hydraulic brakes, combined with heat-dissipating, vented wavy brake discs, deliver smooth and reliable stopping power in any condition.
DC Brushless MotorThe MXR1800 Dirt Bike is powered by the biggest and one of the best motors available in this range. With a huge, grunty brushless 1800w motor, this bike really pulls and is the perfect next step up from our 1300w & 1400w electric MXR. Not content with 36V, we’ve made this 48V for a longer ride time over the 36V. 
Twistgrip ThrottleClassed as a mini dirt bike, the twistgrip throttle unit gives the MXR1800 an original dirt bike feeling, alongside an LCD battery display indicating how much longer you have to continue enjoying the ride! 
Rear ShockThe MXR1800’s rear mono-shock absorber delivers exceptional performance, enhancing overall handling and ensuring a smooth, controlled ride over rough terrain. It feels great and provides the comfort and stability needed for an unbeatable riding experience, even on challenging surfaces.

Equipped with proper MX tread tyre, it offers superior grip and traction, ensuring maximum control and performance on any terrain. Perfect for young riders ready to take their adventure to the next level!
Speed DialsOne unique feature is the intelligent control unit which allows the user to control; Throttle Response – choose how you want the power delivery, sporty & aggressive, soft & gentle, or somewhere in between? Speed Setting – you set the top speed (from 6 to 32mph). 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.
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.
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.
This product is capable of speeds up to 32mph and includes adjustable speed restrictor settings/dials. 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 14+.
Parents and guardians must assess suitability based on the rider’s size and ability.
