Duotts F26 Electric Fatbike 1500W | Sähköpyörätehdas

DUOTTS F26 Electric Fat Bike – When the Electric Bike Factory’s test team returned in silence

It started out as usual: the test team at an electric bike factory was invited to test a new bike. Just another day, just another test. But when they saw the DUOTTS F26 electric fatbike for the first time, they fell silent. One engineer dropped his coffee cup. Another took off his helmet and whispered:
“That’s not an electric bike. That’s a wild beast.”

Throughout the day, the test team rode through the city, up into the mountains, through mud, along sandy trails, across a construction site, and down a cliff (not on purpose, but the DUOTTS F26 handled it just fine). When they returned, they didn’t mention any other bikes. They talked about only one: the DUOTTS F26 electric fat bike.

🔥 This is where your customer makes a decision

The DUOTTS F26 electric fat bike is more than just a bike. It’s a machine built to crush the terrain, devour kilometers, and give you the feeling that you’re ruling the planet on two wheels.

💪 Power? Yes, please:

Two 48V 750W brushless motors – A total of 1,500 watts of madness.
65 Nm x 2 of torque – It’ll pull you up the hill before you even have time to yell “Help!”
48V 20Ah Samsung battery – 120 km with pedal assist, 60 km on electric power alone.
Hydraulic disc brakes – They stop you in your tracks. But with style.

🌲 Out in nature, in the city, and on the upstairs balcony

The DUOTTS F26 electric fat bike isn’t limited to just one use. Ride it through the park on your way to work, take it on a mountain trail on the weekend, and experience how the 26×4” tires glide over mud, gravel, and asphalt like a butter knife through warm rye bread.

The test group climbed a 35° incline on rocky terrain. They made it—without breaking a sweat. The rider was sweating, but the bike just smiled.

🧠 Cleverly designed, insanely powerful

The LCD color display tells you everything: speed, distance, battery level—and it looks great, too.

⚡ DUOTTS F26 Electric Fatbike – Why this one in particular?

Because life is too short to ride a boring bike.

The DUOTTS F26 electric fat bike is built for those who refuse to compromise. Power, durability, technology, and above all: attitude. This bike doesn’t ask, “Can you ride there?” but rather, “Do you dare?”

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.
