Let yourself be seduced by the performance of the Mini Bike Fossa Fun 49cc – Adventure within reach!
The Mini Bike Fossa Fun 49cc from Nitro Motors is much more than just a motorized toy: it is a machine designed for thrill-seekers, combining compactness, maneuverability, and robustness. Whether you are a young budding rider or an adult looking for a lightweight vehicle for fun sessions on private terrain, this Mini Bike cross will impress you. With its 2-stroke 49cc engine developing 1.8 kW and a top speed of around 50 km/h, it offers an ideal power-to-weight ratio (only 23 kg empty) for lively accelerations and responsive handling. At RiderProShop, we have selected it for its quality of manufacture and high-end equipment, rare in this category.
A reinforced chassis and an aluminum swingarm for optimal road holding
The Mini Bike Fossa Fun stands out with its aluminum swingarm, a key component for absorbing shocks and ensuring optimal stability, even on rough terrain. Unlike lower-end models equipped with heavy, less resistant steel parts, this crossbike benefits from a design focused on performance. The ground clearance of 260 mm and wheelbase of 850 mm offer a perfect balance between agility and control. RiderProShop Expert Tip: To extend the life of the swingarm, regularly check the tightness of the bolts and lubricate the pivots after each use in muddy or dusty conditions.
Wave disc brakes: braking power worthy of big cross bikes
Equipped with front and rear Wave disc brakes, the Fossa Fun 49cc offers a braking system usually reserved for competition motorcycles. These discs, recognizable by their wavy shape, dissipate heat better and reduce the risk of fading (loss of effectiveness) during repeated braking. A major advantage for demanding riders who want to master their Mini Bike safely. Our recommendation: After the first 10 hours of use, check the wear of the pads and adjust the brake cable if necessary to maintain an immediate response at the lever.
Rear Upside-Down shock absorbers: the comfort and precision of a true dirt bike
The Mini Bike Fossa Fun features a Upside-Down rear shock absorber (upside down) and a preload-adjustable aluminum spring combination – a rare configuration on entry-level mini-motos. This system allows you to adjust the suspension firmness to your weight (up to 60 kg maximum load) and the type of terrain. Whether you're riding on a dirt track or a forest trail, you'll enjoy grip and comfort worthy of a professional dirt bike. RiderProShop Tip: For optimal adjustment, start with a medium preload, then adjust in 1/4 turn increments based on your feelings.
Chain transmission and automatic clutch: simplicity and reliability
The chain transmission of the Fossa Fun 49cc is protected by an integrated chain guard, limiting mud splashes and the risk of breakage. Coupled with an automatic clutch, it eliminates jerking during acceleration and makes it easier for beginners to handle. No need to disengage: the system naturally adapts to your speed. Good to know: To extend the life of the chain, clean it after each use with a degreaser-soaked cloth, then lubricate it with specific oil (available in our maintenance section). A well-maintained chain also reduces wear on the sprocket and pinion.
Easy Starter and kill switch: safety and practicality every day
Forget about temperamental starters! The Mini Bike Fossa Fun is equipped with an aluminum Easy Starter puller, a cable-driven ultra-resistant system that ensures a first-time start, even after a long period of inactivity. Another important detail: the kill switch cord (or "kill switch"), attached to the handlebar, allows you to instantly stop the engine in case of an emergency. RiderProShop Safety: Before each use, pull on the cord to check that the kill mechanism is working correctly. If replacement is needed, opt for a quality cord (reference available as a spare part).
Power restriction in 3 levels: for progress adapted to all
With its 3-speed restriction system (adjustable via the rotating throttle grip), this Mini Bike adapts to all levels of riding. The first position limits the power for beginners, while the third unleashes the full capacity of the 49cc engine. An ideal function for parents wishing to accompany their children's learning, or for experienced riders who want to adjust performance according to the terrain. Our advice: Always start with level 1 to familiarize yourself with the engine's responsiveness, especially if you are moving from a pocket bike to a more powerful model like this crossbike.
Ergonomic handlebar and optimized exhaust: the detail that makes the difference
The raised handlebar of the Fossa Fun 49cc offers a natural riding position, reducing fatigue during long sessions. The exhaust, designed for optimal performance, limits back pressure and improves engine response. Technical Tip: After 50 hours of use, check the exhaust fixings and clean the silencer with an anti-rust product to prevent corrosion, especially if you ride in wet conditions. For riders concerned about noise pollution, an approved silencer can be added (see our compatible accessories).

Wave disc brakes (front and rear) require regular maintenance:1. Cleaning: After each use on muddy terrain, clean the discs and calipers with a damp cloth to prevent corrosion.2. Pad check: Check the remaining thickness (replace if < 2 mm). Pads wear faster in cross use than in road use.3. Bleeding the system (if necessary): If the braking feels soft, bleed the braking system (requires a bleeding kit and DOT 4 brake fluid).4. Lubrication: Lubricate the wheel axles to prevent seizing.5. Adjustment: Adjust the brake cable tension if the lever becomes too soft.We offer compatible pad and disc replacement kits.
