DYU Stroll 1 700C – The New King of City E-Bikes

🚴‍♂️ Test-ridden right at the factory—our e-bike team fell in love with it right away

When Sähköpyörätehdas’s own test team flew to the DYU factory to test ride the DYU 250w city e-bike, expectations were high—but the Stroll 1 still surprised everyone. First, we rode it on the factory’s indoor track, then straight out onto city streets, up steep hills, and even down dimly lit alleys. The result? Smiles, praise, and just one question: “When will this go on sale?”

One of the testers exclaimed upon returning
“This is the most agile and lightweight DYU 250w city e-bike I’ve ever ridden—and yet it still powers uphill like an electric train!”

Toinien noted
“The ride is smooth, the frame is wonderfully light, and the brakes respond like those of a sports car. This isn’t just a bike—it’s a phenomenon.”

🔋 A smartly designed power package

The DYU 250W electric bike is equipped with a high-quality 250W motor (peak power 500W), which, combined with a 36V 9Ah removable battery, offers a range of up to 100 kilometers. You can ride to work, go on weekend trips, and take evening rides without worrying about running out of power.

🛑 Hydraulic control and puncture-resistant tires

The DYU 250W e-bike is designed specifically for city riding: it features front and rear hydraulic disc brakes that provide smooth and safe stopping power in all weather conditions. The 700×38C CST tires are puncture-resistant and provide a secure grip on asphalt, gravel, or cobblestones.

✨ Lightweight yet stable—it’s like driving on air

The Stroll 1 weighs just 19.5 kg—thanks to its lightweight yet durable aluminum frame. This makes the bike exceptionally agile. The DYU 250w city e-bike doesn’t feel heavy; in fact, its lightness makes it feel more like a piece of sports equipment than a mode of transportation. It glides smoothly through turns and accelerates just right amid the hustle and bustle of the city.

💡 See and Be Seen – Modern LED Lighting and Displays

The safety of urban cyclists hasn't been overlooked. The bright LED headlight at the front provides peace of mind when riding in the dark, and the stylish LED display shows you everything you need to know: speed, battery level, riding mode, and much more. The display lets you easily adjust your ride to suit the situation.

⚙ Three driving modes—the one that's right for you

Whether you’re in the mood for a leisurely ride or need a brisk commute, the DYU 250w city e-bike’s three assist modes adapt to your daily life. And with an adjustable seat, the bike fits riders between 170 and 220 cm without compromise.

📦 Included in the package:

DYU Stroll 1 Electric Bike
Removable 36V 9Ah battery
Charger
Pedals
Multifunctional tool
Bottle Holder
User's Manual and Warranty Certificate

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.
