DUOTTS F26 Lite 500W Electric Fat Bike – A Silent Beast on the Shores of Helsinki

It was still damp in Kruunuvuorenranta in the early morning when the Sähköpyörätehdas test team received a message:

“The new DUOTTS has arrived.”

A short time later, the box was opened at the joint test track for European electric bike manufacturers in Helsinki.

And that was it.

DUOTTS F26 Lite 500W electric fat bike with a hand throttle.

Wide 26×4.0” tires. An aggressive frame. A hidden battery. And a look that seemed more like a machine than a typical electric bike.

One of the test riders walked slowly around the bike and said:

“That looks like it’s not going to stop anywhere.”

It soon became clear that he wasn't wrong.

🔥 First test drive – the perfect combination of power and stability

When the DUOTTS F26 Lite electric fat bike set off for the first time, the whole bike felt different from regular electric bikes.

The 500W motor responded instantly. The half-twist throttle made acceleration smooth yet powerful. And the fatbike tires provided a sense of stability that you can’t truly understand until you try it yourself.

This is not a lightweight city bike.

This is a true electric-assist fatbike that feels safe even when the road gets rough.

The bike rides smoothly on asphalt.

But the real fun doesn't start until the road ends.

🌲 Sand, snow, gravel, and forest trails—that’s where the F26 Lite belongs

The test team headed away from the streets of Helsinki toward gravel roads and forest trails.

The first thing everyone noticed?

Grip.

The DUOTTS F26 Lite electric fat bike rides smoothly even on soft terrain. The 26×4.0” Kenda tires grip the ground in a way that ensures a stable ride even on sand, mud, and uneven trails.

And when they came to a long uphill stretch, one of the drivers floored it.

The bike rose up without hesitation.

This mountain fat bike doesn't feel heavy or slow.

It feels like it was made for challenging trails.

⚡ 500W motor + twist-grip throttle = an e-bike you'll actually want to ride

Many electric bikes look good on paper.

But when you're driving, they feel like any other car.

The DUOTTS F26 Lite electric fat bike with a hand throttle doesn't feel like that.

The 500W motor provides smooth yet powerful traction
65 Nm of torque makes uphill climbs a breeze
The hand throttle allows for fully electric driving without pedaling
The 48V 18Ah battery provides a long range

This wide-tire electric bike is designed for people who want more than just a standard commuter bike.

🧠 A smart driving experience in every situation

The DUOTTS F26 Lite electric fat bike combines performance and practicality in a way that makes every ride easier.

The LCD screen displays speed, battery level, and trip data in real time
Bluetooth connectivity allows you to connect to the Duotts app
Hydraulic disc brakes provide reliable stopping power in all conditions
The built-in battery gives the frame a sleek and stable design

This all-terrain electric bike isn't just powerful.

It was built for its intended use.

🌍 Built for all types of driving

Commuting? Easy.
Forest trails? Even better.
Winter driving? Perfect.

The DUOTTS F26 Lite electric fat bike combines:

the stability of a fat bike
the ease of an electric bike
mountain bike performance
and the freedom that comes with a hand throttle

This isn't a bike that's only used in the summer.

This is the bike you'll want to ride all year round.

You won't want to go back to regular tires.

🎯 The final vibe

When the test team returned to the test track in Kruunuvuorenranta, one of the riders stayed seated on the bike in silence for a moment.

Then he looked at the others and said:

“You could drive this even in the middle of winter without any worries.”

And that's exactly what the DUOTTS F26 Lite 500W electric fat bike with a hand throttle is known for.
