KOOLUX X10 350W Folding Fatbike – a compact, foldable electric fatbike for city riding and leisure
The KOOLUX X10 folding electric fat bike combines a compact size, wide tires, and modern electric assist into one stylish package. This e-bike is designed specifically for city riding, commuting, and easy everyday use, but thanks to its wide 16×3.0” tires, it also rides smoothly on gravel roads and uneven surfaces.
During the Sähköpyörätehdas team’s test ride, the KOOLUX X10 particularly impressed with its agility and stability. Although it is a compact folding e-bike, the ride felt significantly sturdier and more comfortable than many would expect from a bike in this size class.
⚡ Compact, foldable e-bike with powerful performance
The KOOLUX X10 electric bike offers smooth yet powerful electric assistance, making it easy to ride around town, commute to work, and enjoy your free time. The electric system responds quickly to acceleration, making riding a pleasure even on hills.
The smaller frame size makes the bike particularly agile when riding in the city, on narrow bike paths, and in congested areas.
🔋 36V 13Ah lithium battery – a practical range for everyday use
The KOOLUX X10 is equipped with a 36V 13Ah lithium-ion battery, which provides a range of approximately 50–65 kilometers on a single charge. This makes the e-bike an excellent choice:
🚴 For commuting
🏙️ For city riding
🛒 For daily errands
🌆 For evening rides and leisure time
The battery charges in about 7–8 hours and provides reliable performance for everyday use.
🛠️ Foldable frame – perfect for small spaces
One of the biggest advantages of the KOOLUX X10 electric bike is its foldable design, which makes it easy to:
🚗 Transport in the trunk of a car
🏡 Store in a small apartment
🚆 Take on public transportation
⛵ Use in a motorhome or boat
Its compact size, combined with wide tires, makes the bike extremely practical yet stable to ride.
🛞 16×3.0” fatbike tires – stability and comfort
The wide 16×3.0” tires offer significantly more stability than traditional city e-bikes. They provide a smoother ride and better traction, especially:
✔ On gravel roads
✔ On cobblestones
✔ On wet asphalt
✔ On uneven surfaces
During our team's test drive, the tires received a lot of praise for the smoothness and stability they provided.
⚙️ Modern display and app connectivity
The KOOLUX X10 electric bike is equipped with an S869 LCD display and mobile app support, which allow you to easily track:
🔋 Battery charge
⚡ Speed
📍 Ride data
🚴 Riding mode
The clear display makes using the electric bike easy, even for first-time users.
🛑 A safe driving experience in all conditions
The KOOLUX X10 electric bike is equipped with front and rear disc brakes, which provide effective stopping power even in the rain and on slippery surfaces.
The IP54 water resistance rating helps protect the electrical system in Finland's variable weather conditions.
