DUOTTS C29 Max 500W Electric Mountain Bike – The Bike That Doesn't Ask Where to Go

That day in Kruunuvuorenranta started completely normally.

Sähköpyörätehdas received a new model: DUOTTS C29 Max 500W electric mountain bike with hand throttleIt was delivered directly to the European e-bike factories' joint test site in Helsinki – a place where every bike has to prove its worth in the real world.

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

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


🔥 First driving feeling – perfect control

When the DUOTTS C29 Max 500W electric mountain bike took off, the difference was immediately noticeable.

This is not a traditional electric bike. This is an electric mountain bike with more than enough power – and above all, a hand throttle that changes the entire riding experience.

You're not just pedaling anymore.

You can choose.

Light pedal assist?
Full electricity?
Or do you let the gas handle everything?

In the city, this bike moves quickly and effortlessly. It feels light but responds instantly – just like a powerful electric bike should.


🌲 In the field – the true nature is revealed

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

Sand. Rooty forest. Uneven paths.

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

The 29” tires roll over obstacles without hesitation. The front suspension absorbs the bumps. And when you press the gas – the bike responds immediately.

This is not just an off-road electric bike.

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

And with a long uphill ahead, the test driver made a decision:

No pedaling.
Just gas.

And it rose.


⚡ 500W motor + hand throttle = complete freedom

The DUOTTS C29 Max 500W electric mountain bike with hand throttle is built for one thing:

for freedom.

  • 500W motor provides significantly more power than basic EU models
  • 65 Nm of torque will get you up hills without drama
  • Hand throttle allows driving without pedaling

This is not just an electric bike.

This is an alternative to a scooter – but lighter, quieter and more versatile.


🧠 Smart driving experience – you decide how you drive

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

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

This is not a compromise between electrical and muscular power.

You get both.


🌍 Built for real use

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 a city bike
  • Mountain bike durability
  • The ease of an electric bike
  • And the freedom of gas-powered driving

This is a bike you can ride wherever you want – without wondering if you can handle it.

🚀 Why customers choose this bike

This is no longer just a spec choice.

This solves real problems:

  • ❌ “I can’t pedal the whole way”
    → ✔️ Drive on gas only
  • ❌ “Hills kill the mood”
    → ✔️ 500W motor handles climbs
  • ❌ “The electricity is running out”
    → ✔️ Long range = less charging
  • ❌ “I don’t know if this is right for me”
    → ✔️ Suitable for most riders (170–200 cm / 150 kg)

⚠️ The truth that few tell

Many electric bikes look good on paper.

But when driving, they feel… mediocre.

DUOTTS C29 Max 500W electric mountain bike no.

  • It reacts immediately
  • It doesn't clot.
  • It feels powerful every second.

  • ✔️ You want more power than basic electric bikes

⏳ Why you should buy this now

  • 🔥 arouse the most interest
  • 🔥 will be annoying if you don't buy in time

🎯 The ultimate feeling

When the test team returned to Kruunuvuorenranta, one thing was clear:

This isn't a bike you just ride from A to B.

This is the bike you want to ride – without a destination.

DUOTTS C29 Max 500W electric mountain bike.


🎯 The ultimate feeling

When the test team returned to Kruunuvuorenranta, one thing was clear:

This is not a bike to compare to others.

This is the bike that others are compared to.

Manufacturer's warranty – you deal directly with the factory that sold the bike

The seller of an electric bike is the factory that manufactures or supplies the bike. The factory is the independent and sole seller of the electric bike store and is responsible for the product's delivery, warranty, and any possible defects.

Sähköpyörätehdas Suomi Oy is not a seller or guarantor of the electric bike. Sähköpyörätehdas offers you a separate customer service and technical system through which you can contact the factory's salesperson.

How to handle warranty issues

After ordering, you will receive personal usernames that allow you to chat directly with the factory salesperson.If your e-bike has a fault:

  1. Log in to the service with your own usernames.
  2. Start a conversation with the factory that sold you the bike.
  3. Describe the problem as precisely as possible.
  4. Please include photos, videos, order number, and other necessary information requested by the factory.
  5. The factory salesperson will assess the matter and provide instructions for inspection, spare parts, repair, or other warranty processing.

Maintenance and assembly of electric bikes at the electric bike factory

Your e-bike can be serviced either at our Helsinki store or at service shops located elsewhere in Finland. You can easily find your nearest service point at [this link].

Assembling an electric bike

When you buy an electric bike from us, you can be confident that everything has been made as easy as possible for you. Our electric bikes are 90% pre-assembled, which means you don't have to worry about complicated assembly steps. For the final assembly, you will receive all the necessary tools and clear, step-by-step instructions to ensure that your electric bike is ready to ride in just around 30 minutes.

However, if you need help at any stage, we’re here to help. You can contact us at any time, and we offer free video tutorials via WhatsApp to help you get started. If you still don’t want to assemble your 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 maintenance should be done after about a month of riding or after the e-bike has been ridden for 100-300 kilometers. This initial maintenance includes a complete washing of the e-bike, a comprehensive check of the electrical components, brake and gear adjustments, spoke tightening, chain oiling, and a general condition check. This maintenance 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 oiling, and checks and updates to all electrical systems. We recommend annual maintenance regardless of how you use your e-bike, to keep it in top technical condition and safe all year round.

Prices for maintenance and assembly services

We keep maintenance costs competitive. The price of initial maintenance starts at 90 EUR, and comprehensive annual maintenance costs 149 EUR (incl. VAT 25,5%).

If you want us to assemble your e-bike for you, you can bring it to our store, and the assembly service costs 69 EUR.

Maintenance and assembly booking

You can book maintenance or assembly by calling our store directly or visiting our website.

If you are unable to get to our Helsinki store, you can take advantage of our service network covering the whole of Finland. [Click here] to see all our service points and their contact information.
