Onesport OT01 250W City E-Bike

OneSport OT01 City E-Bike – The Legend of Kruunuvuorenranta Is Born

The child seat andluggage racks are included in the price!

When the OneSport OT01 city e-bike arrived at the joint test ride site for European e-bike manufacturers in Kruunuvuorenranta, Helsinki, the atmosphere was charged with anticipation. This was no moped—it was a large, full-size bike that exuded power and urban vibes. When the test team pedaled off for the first time, the street fell silent—and the sounds of the city became nothing more than background noise as they picked up speed.

“When the OT01 loaded its long trailer to capacity and began climbing the Kruunuvuori slopes, everyone knew that not even all of Helsinki could keep up.”

⚙️ The Power of the Engine – The City Listened

The OneSport OT01 city e-bike is equipped with a powerful 500 W motor that delivers up to 62 Nm of torque—enough to propel the bike through the hustle and bustle of the city and up even the steepest hills. With the electric assist, even a heavy cargo feels as light as a feather while staying within the EU speed limit of 25 km/h.

🚘 City Driving – Master of the Concrete Jungle

With 20″ x 2.6″ wheels and an aluminum frame, the OT01 handles with agility—whether loaded with a cargo basket or not—and zips through traffic like it’s on a racetrack. Hydraulic disc brakes front and rear, along with 203 mm brake rotors, provide unbeatable control when traffic clears.

🏝️ Off-road section – adventure awaits

The off-road section takes the OT01 onto the uneven trails of Kruunuvuori—the front suspension absorbs the bumps, and the tires grip the trail. The rear cargo rack doesn’t get in the way; instead, it adds stability and carrying capacity—whether you’re hauling kids, dogs, or grocery bags.

🔋 Battery & Range – Go Further and More Often

The built-in 48 V / 27 Ah battery provides a range of up to 80–100 km in assisted mode, and charging takes an average of 8–10 hours—fully charged overnight and ready to go by morning. Simple and reliable power for everyday use.

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.
