Accessories

The F21 is equipped with a high-brightness LED lighting system combined with integrated turn signals, ensuring clear visibility in low-light environments and complex traffic conditions. Whether riding through city streets at night or navigating dim off-road trails, the lighting system enhances rider awareness while making intentions clearly visible to others, significantly improving overall safety and confidence on every journey.

Featuring a hydraulic disc braking system, the F21 delivers precise and responsive stopping power across a wide range of terrains. From steep mountain descents to wet or muddy paths, riders can rely on consistent braking performance with minimal effort, allowing for better control, shorter stopping distances, and a safer riding experience even under demanding conditions.

The 20×4.0 fat tires are designed to provide exceptional grip and stability, making the F21 highly adaptable to challenging surfaces such as sand, snow, and uneven terrain. Their wide contact area not only enhances traction but also absorbs shocks from rough roads, ensuring a smoother and more stable ride, even when carrying additional cargo or riding over long distances.

Recommended Use

Mountain Riding

Built for rugged trails and steep climbs, the F21 combines its powerful 1200W motor with a dual-suspension system to handle uneven terrain with ease. Riders can confidently tackle rocky paths, sharp inclines, and unpredictable trail conditions while maintaining stability, comfort, and control throughout the journey.

Snow & Sand

On soft and slippery surfaces where standard bikes struggle, the F21 performs with confidence thanks to its fat tire design and strong power output. Whether riding across snowy paths or sandy landscapes, it maintains traction and balance, allowing for a smooth and controlled ride without sinking or slipping.

Urban Commuting

Beyond off-road performance, the F21 is equally suited for daily urban commuting. Its stable frame, smooth ride quality, and integrated safety features make it ideal for navigating busy streets, while the cargo-ready design allows riders to carry daily essentials with ease, offering both practicality and efficiency in everyday use.
