COMING SOON! CMACEWHEEL EM20 350W 36V 12AH CITY ELECTRIC BIKE is a true game-changing electric bike for urban mobility. The Electric Bike Factory test team had the honor of testing this stylish and high-performance bike at the Kruunuvuorenranta shared test site in Helsinki. This bike combines carefully considered technology with a smooth riding experience that makes everyday urban adventures even more enjoyable.
Top-level urban cycling and performance
The CMACEWHEEL EM20 stands out for its agile performance. The 350W motor and 12Ah battery provide powerful and smooth assistance, perfect for both leisurely city rides and demanding climbs. Hydraulic disc brakes provide confident stopping power in tight situations, and the five-speed Shimano 7-speed transmission keeps the ride smooth and immediate.
A carefully designed and versatile driving experience
Our test team was surprised by the bike’s versatility, especially in urban traffic, but also on more challenging trails in the Kruunuvuorenranta terrain. IP65-rated water resistance combined with flexible 20-inch tires allows you to ride both on asphalt and slightly uneven trails. Three riding modes – human power, assisted and full electric – give you options for your riding style.

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.

This maintenance ensures that your e-bike is in top condition and ready for safe riding.

We recommend annual maintenance regardless of how you use your e-bike, to keep it in top technical condition and safe all year round.
