Duotts C29 750W - An electric city bike at up to 75% off.

DUOTTS sent us the new C29—and we fell in love with it right away

The test team’s phone rang early in the morning. On the other end of the line was the logistics manager from the DUOTTS factory, who said, “The DUOTTS C29 city e-bike is on its way to you—make the most of it.”

A couple of days later, a massive box arrived at Sähköpyörätehdas’s test ride location in Laajasalo, Kruunuvuorenranta. We didn’t know at the time that this would turn out to be one of the most memorable test rides we’ve ever experienced.

💥 First moments in the saddle

The box is open. The DUOTTS C29 city e-bike glistens in the evening sun. The frame’s design exudes power, yet also a streamlined elegance. The motor is 750W—and you can definitely feel it.

The power turns on. The display flashes the speed, battery level, and assist mode. We set the assist to maximum. The first push. The bike takes off like a rocket.

🌇 City driving – as smooth as velvet

We’re riding from Kruunuvuorenranta toward Herttoniemi. The DUOTTS C29 city e-bike glides effortlessly along the bike paths. Its 29-inch pneumatic tires feel like a hovercraft on the asphalt. Crosswalks, rocks, curbs—nothing fazes this bike.

The motor is completely silent, yet incredibly powerful. The Shimano 21-speed drivetrain ensures that every street corner feels like a new opportunity.

🏞️ Off-road test – this isn't just any city bike

Next, we’re heading out onto the forest trails. Vuosaari has trails that would be too much for many e-bikes. But the DUOTTS C29 city e-bike can handle anything.

The 65 Nm of torque really kicks in on steep climbs. The front suspension absorbs bumps so smoothly that it feels like you’re gliding over roots and rocks. The bike is light but sturdy. That makes it ideal for these Finnish conditions.

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.
