Regulations & Legal Obligations

Our motorcycles, quads, pocket bikes, etc., are not approved for use on public roads. Their use is strictly limited to closed, private tracks that comply with the provisions of Article R 331-21 of the French Sports Code.

Our vehicles (motorcycles, quads, buggies, etc.) intended for children should not be considered mere toys, but motorized machines belonging to the realm of motorsports, which involve inherent risks.

Minors under the age of 14 are not authorized to purchase, rent, or use non-approved vehicles, such as mini-motorcycles, children's quads, unapproved quads, motocross bikes, pocket bikes, pocket cross bikes, pit bikes, or dirt bikes. Their use is strictly limited to activities organized by approved sports associations, such as the FFM (French Motorcycling Federation) or UFOLEP (French Union of Secular Sports and Cultural Activities). It is important to note that the maximum speed of these vehicles on public roads is 24 km/h, which prohibits their use on public roads. Furthermore, minors under 16 years of age must be constantly supervised by an adult when using these machines.

To ensure your safety, it is essential to wear appropriate protective equipment, including an approved safety helmet, motocross-type safety glasses, gloves, elbow pads, knee pads, and a chest protector. It is also recommended to wear a long-sleeved top, long trousers, and high-top shoes that cover at least the ankle, ensuring that the laces are securely tied and away from the wheels, engine, and drive system.

You must register your machine with the Ministry of the Interior within 15 days of the purchase date. This process can be completed online at the following address: https://www.service-public.fr/particuliers/vosdroits/R20458. After submitting the declaration, you will receive an identification number to be engraved on the chassis and displayed on a visible plate. Please note that this plate can be removed during sporting activities.

We also encourage you to consult the charter outlining the rules to be followed for the use of your vehicle, available here: https://www.legifrance.gouv.fr/loda/id/JORFTEXT000020910287/, or to refer to the user manual, which you can download.

Assembling your bike:

You will only need to finish assembling a few easy parts (such as the handlebars, front wheel, and rear shock absorber).

Once assembly is complete, if the factory settings are not perfectly suited to your riding conditions, we invite you to visit our YouTube channel (Mini MX) where you will find both mechanical tutorials and bike assembly videos.

We recommend that you read the owner's manual and check the general tightening of your motorcycle (spokes, axle, general screws), chain tension, tire pressure, and the routing of the brake/clutch cables.

We recommend that you perform your first oil change using IPONE or Putoline oils, as recommended and approved by the manufacturer. Using other oils not approved by the manufacturer could damage the engine or gearbox.

Our after-sales service, based in Fréjus (83), France, is available at 0972390537 (free call) to assist you if you have any questions.
