OneSport OT16-2 250W City E-Bike | Sähköpyörätehdas

🚴‍♂️ Onesport OT16-2 City E-Bike – The test group in Kruunuvuorenranta, Helsinki, fell silent

In the world of electric bikes, there are moments when silence speaks volumes. When the Onesport OT16-2 city e-bike was shipped from Duotts’s headquarters to the joint test track for European e-bike manufacturers in Helsinki, no one was expecting miracles.

But then came the morning when the test team rolled this folding bike off the trailer onto the Kruunuvuorenranta waterfront boulevard. The city was waking up, the sun rose from behind the fog, and the bike’s silhouette was reflected on the water’s surface—as if in a scene where the product and its surroundings found each other perfectly.

The first few pedals felt light. Then the motor kicked in.
The 250W brushless motor provided smooth acceleration, like an electric train without tracks.
“Quiet but powerful,” remarked the first test rider.
Another added: “This isn’t just an electric city bike. This is the new standard in mobility.”

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.

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).
