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.
👤 Who is the KOOLUX X10 electric bike best suited for?
This foldable electric fat bike is perfect for:
🚴 For city riding
🏢 For commuting
🏡 For those who need a little storage space
🚆 For public transit users
🌆 For beginners and experienced e-bike riders
🧳 For a motorhome or boat

Maintenance and Assembly of Electric Bikes at the Electric Bike Factory

You can have your electric bike serviced either at our store in Helsinki or at service centers located elsewhere in Finland. You can easily find your nearest service location [here].

Assembling an Electric Bike

When you buy an e-bike from us, you can rest assured that we’ve made everything as easy as possible for you. Our e-bikes come 90% pre-assembled, which means you don’t have to worry about complicated assembly steps. For the final assembly, you’ll receive all the necessary tools and clear, step-by-step instructions to ensure your e-bike is ready to ride in just about 30 minutes.

However, if you need help at any stage, we’re here to assist you. You can contact us at any time, and we offer free video guidance via WhatsApp to ensure the assembly goes smoothly. If you’d still rather not assemble the e-bike yourself, you can also bring it to our store, and we’ll assemble it for you—this service is also designed to keep the process easy and hassle-free.

First Aid

The first service should be performed after about one month of riding or when the e-bike has been ridden 100–300 kilometers. This initial service includes a thorough wash of the e-bike, a comprehensive inspection of the electrical components, adjustments to the brakes and gears, tightening of the spokes, lubrication of the chains, and a general condition check. This service ensures that your e-bike is in top condition and ready for safe riding.

Annual Maintenance

Annual maintenance includes even more comprehensive procedures: battery testing, drivetrain cleaning, tire inflation and replacement, chain lubrication, and inspections and updates of all electrical systems. We recommend annual maintenance regardless of how often you use your e-bike, to ensure it remains in top technical condition and safe to ride all year round.

Prices for Maintenance and Repair Services

We keep our maintenance costs competitive. The price for an initial service starts at 90 EUR, and a comprehensive annual service costs 149 EUR (including 25.5% VAT).

If you'd like us to assemble your electric bike for you, you can bring it to our store; the assembly service costs 69 EUR.

Service and Assembly Appointment

You can schedule a service appointment or a pickup by calling our store directly or visiting our website.

If you can't make it to our store in Helsinki, you can take advantage of our service network, which covers all of Finland. [Click here] to see all of our service locations and their contact information.
