ECONO Apes CITY EER4 Electric Bike
Designed for comfortable city riding and relaxed exploration.

Who is this electric bike best suited for?
The ECONO Apes EER4 electric bike (2025 model) is the perfect choice for cyclists who value comfort, simplicity, and reliability in their daily city rides. It is ideal for commuting to work, running errands, or for leisurely trips on flatter terrain. With its comfortable geometry, which includes a wide saddle, an adjustable handlebar, and a curved design for an upright posture, it ensures a relaxed and carefree cycling experience.

Reliable Bafang Motor for the City Pulse
The bike is powered by a strong and proven Bafang H400B rear hub motor with 250 W of power and 40 Nm of torque. This motor, located in the rear hub, works in combination with a cadence sensor, providing smooth, responsive, and intuitive pedaling assistance. It is ideal for the urban environment, allowing for easy starts and effortless navigation of daily routes.

A Customizable Battery Tailored to Your Needs
Power is supplied by a reliable ECONO battery, which we develop and assemble in Slovenia. It is available in three different capacities, so you can choose the range that best suits your needs: 520 Wh, 700 Wh, or 800 Wh. All batteries are easily removable and interchangeable between our 2025 models, giving you maximum flexibility.

Clear Display and Easy Operation
You can monitor all your ride data on the compact and clear Bafang DP C080 color display, mounted on the side of the handlebar. With simple buttons, you can choose between five levels of motor assistance: ECO, TOUR, SPORT, SPORT+, and BOOST. This allows you to always adjust the assistance level to the terrain and your desired effort while riding.

Comfort Comes First
For a smooth and comfortable ride on city streets, the SR Suntour NEX front suspension fork with 75 mm of travel effectively absorbs bumps. Comfort is enhanced by a wide Velo saddle, ergonomic grips, and an adjustable stem, which allows for perfect positioning for the most relaxed and enjoyable ride possible.

Reliable Braking and Shifting
Your safety is paramount, which is why the bike is equipped with powerful Tektro HD-M280 hydraulic disc brakes. With 180 mm front and 160 mm rear rotors, they provide maximum stopping power and reliability in all weather conditions. The 9-speed Shimano Altus derailleur ensures precise and smooth shifting.

Fully Equipped for Everyday Use
The ECONO Apes EER4 is ready for all the challenges of city life. The bike comes standard with all the necessary accessories: front and rear LED lights for better visibility, fenders for protection against water and dirt, a durable rear rack compatible with the MIK system, and a convenient kickstand for easy parking.
