COMING SOON! The DYU C2 250W 16″ folding electric bike is a new generation urban adventurer that combines performance and practicality in a unique way. The test team at the Electric Bike Factory got their hands on this magnesium alloy frame and compact folding DYU C2 and took it for a challenging test on the diverse terrain of Kruunuvuorenranta in Helsinki. In this story, we tell you why this electric bike is an excellent choice for city streets, off-road trails, and even steep hills.
Fast city driving and smooth movement
The Kruunuvuorenranta test tracks revealed the best aspects of the DYU C2 right from the first meters. The 250 W motor support and the peak power of 500 W guarantee smooth acceleration and easy progress even in congested city conditions. The centrally placed front suspension comfortably smooths out unevenness, and the 16 x 2,5 inch tires keep the bike firmly on the road. Thanks to this lightness and agility, the hustle and bustle of the city turns into an enjoyable riding experience, with the folding frame making it easy to store and transport both at home and on public transport.
Smooth movement and safety
- Magnesium alloy body combines lightness and durability
- Foldable structure makes everyday transportation and storage easier
- Disc brakes at the front and rear ensure quick and safe stopping
- LED display and adjustable saddle for increased comfort
- Powerful 7,5 Ah lithium battery provides up to 40 km of pedal-assist range
The test team's atmosphere in the challenging terrain of Kruunuvuorenranta
The electric bike factory test team took the DYU C2 to the typical Kruunuvuorenranta dirt roads and forest trails. Steep hills were no problem, as the 15-degree gradeability and 48 V motor provided just the right amount of power and assistance. The top speed of 25 km/h and the smart speed and cadence sensor adapt the assistance to the terrain in no time. The test group appreciated the bike's easy handling, lightness (only 23,6 kg) and reliable braking, which made off-road riding enjoyable and safe.
Riding this electric bike allows you to truly experience freedom and agility on city streets, on interesting routes and on demanding hilly sections. The DYU C2 is not just a means of transportation, but a comprehensive experience that makes everyday mobility even smoother – exactly the kind of electric bike that was appreciated at the Kruunuvuorenranta joint test point.
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:
- Log in to the service with your own usernames.
- Start a conversation with the factory that sold you the bike.
- Describe the problem as precisely as possible.
- Please include photos, videos, order number, and other necessary information requested by the factory.
- The factory salesperson will assess the matter and provide instructions for inspection, spare parts, repair, or other warranty processing.
