DUOTTS C29 Max 500W Electric Mountain Bike – A bike that doesn't ask where you're going

That day in Kruunuvuorenranta began just like any other.

Sähköpyörätehdas a new model: the DUOTTS C29 Max 500W electric mountain bike with a twist-grip throttle. It was shipped directly to the joint testing facility for European electric bike manufacturers in Helsinki—a place where every bike must prove its worth in the real world.

When the test team saw it for the first time, one thing stood out immediately:

It wasn't trying to look aggressive.
It already knew it was.

🔥 First driving experience – total control

As soon as the DUOTTS C29 Max 500W electric mountain bike started moving, I noticed the difference right away.

This isn't a traditional e-bike. It's an electric mountain bike with more than enough power—and, above all, a twist-grip throttle that transforms the entire riding experience.

You're not just pedaling anymore.

The choice is yours.

Light pedal assistance?
Fully electric?
Or do you let the gas handle everything?

In the city, this bike moves quickly and effortlessly. It feels light but responds instantly—just as a high-performance e-bike should.

🌲 Out in the wilderness—true character is revealed

When the test team turned off the asphalt, the real test began.

Sand. Dense forest. Uneven trails.

This is where the DUOTTS C29 Max 500W electric mountain bike really shows its true power.

The 29” tires roll over obstacles without hesitation. The front suspension absorbs the shocks. And when you hit the gas, the bike responds immediately.

This isn't just any off-road e-bike.

This is a machine that turns the terrain into a playground.

And when a long uphill stretch lay ahead, the test driver made a decision:

No braking.
Just the gas.

And it rose.

⚡ 500W motor + throttle = total freedom

The DUOTTS C29 Max 500W electric mountain bike with a twist-grip throttle is built for one thing:

for freedom.

The 500W motor delivers significantly more power than standard EU models
65 Nm of torque gets you up the hills without any drama
The hand throttle allows you to drive without pressing the pedals

This isn't just an electric bike.

This is an alternative to a scooter—but it's lighter, quieter, and more versatile.

🧠 A smart driving experience—you decide how you drive

The DUOTTS C29 Max 500W electric mountain bike adapts perfectly to your riding style:

Torque sensor = natural driving feel
Hand throttle = fully electric driving
LCD display = all information at a glance
5 assistance levels = complete control

This is not a compromise between electric power and muscle power.

You get both.

🌍 Built for the right purpose

Commuting? Easy.
Long drives? No problem.
Off-road? That's what it's made for.

The DUOTTS C29 Max 500W electric mountain bike combines:

The practicality of city bikes
Mountain Bike Durability
The ease of riding an electric bike
And the freedom of driving with the gas pedal

This is a bike that lets you ride wherever you want—without worrying about whether you'll have the stamina.
