CMACEWHEEL Y20 – 500W – A folding electric bike that revolutionized the test drive in Kruunuvuorenranta
When the CMACEWHEEL Y20 arrived at Kruunuvuorenranta in Helsinki, the atmosphere was like waiting for a supercar to take to the starting line. The bike was pulled out of the box, and at first glance, its sturdy aluminum frame, 20×4 inch fat tires, and folding mechanism promised power and versatility.
The first few meters on the asphalt said it all: the 500-watt motor came to life and accelerated smoothly but purposefully. The hills of Kruunuvuori were not an obstacle, but a stage – the Y20 climbed even the steep slopes lightly, as if an electric wind had helped the journey.
When the route turned towards forest paths, the CMACEWHEEL Y20 showed its true character. The fat tires gripped sand, gravel and roots, the suspension absorbed the bumps, and the ride became smooth and enjoyable. In the city, it was just as smooth: the powerful disc brakes stopped precisely, and the foldable frame made transfers effortless – whether it was the subway, the bus or the trunk of a car.
The test team agreed: The CMACEWHEEL Y20 is not just an electric bike. It is a whole that combines power, agility and comfort. This bike invites you to adventure and makes every ride feel special.
For city driving and off-road
The CMACEWHEEL Y20 is perfect for commuting, shopping trips and everyday riding. It's agile, fast and easy to carry. When the road turns to trails, its fat tires and suspension make off-road riding smooth and confident.
Rider comfort and practicality
The Y20 weighs around 30kg, but its aluminium frame is foldable and durable. The bike can carry up to 150kg and is well suited for most adults. The recommended rider height is 165-200cm, so it offers a comfortable riding position for riders of all sizes.

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.

First aid
The first maintenance should be done after about a month of riding or after the e-bike has been ridden for 100-300 kilometers. This initial maintenance includes a complete washing of the e-bike, a comprehensive check of the electrical components, brake and gear adjustments, spoke tightening, chain oiling, and a general condition check. This maintenance 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 oiling, and checks and updates to all electrical systems. We recommend annual maintenance regardless of how you use your e-bike, to keep it in top technical condition and safe all year round.
Prices for maintenance and assembly services
We keep maintenance costs competitive. The price of initial maintenance starts at 90 EUR, and comprehensive annual maintenance costs 149 EUR (incl. VAT 25,5%).
If you want us to assemble your e-bike for you, you can bring it to our store, and the assembly service costs 69 EUR.
