COMING SOON! CMACEWHEEL EM20 350W ELECTRIC BIKE

COMING SOON! The CMACEWHEEL EM20 350W 36V 12AH CITY E-BIKE is a true game-changer for urban commuting. The Sähköpyörätehdas test team had the honor of test-riding this stylish and high-performance bike at the Kruunuvuorenranta community test site in Helsinki. This bike combines carefully engineered technology with a smooth riding experience, making everyday urban adventures even more enjoyable.

Top-Notch City Cycling and Performance

The CMACEWHEEL EM20 stands out especially for its agile performance. The 350W motor and 12Ah battery ensure powerful and smooth assistance, perfect for both leisurely city rides and challenging uphill climbs. Hydraulic disc brakes provide reliable stopping power even in tight situations, and the five-speed Shimano 7-speed drivetrain keeps your ride smooth and responsive.

A carefully designed and versatile driving experience

Our test team was surprised by the bike’s versatility, especially in city traffic, but also on more challenging trails in the Kruunuvuorenranta area. Its IP65-rated water resistance, combined with flexible 20-inch tires, allows you to ride on both asphalt and slightly uneven trails. Three riding modes—pedal-powered, assisted, and fully electric—offer options tailored to your riding style.

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.
