Electric bike ECONO Mare EEC4 CITY
A premium city-trekking electric bike with a powerful mid-drive motor for an exceptionally natural riding feel and complete comfort.

Who is the electric bike ECONO Mare CITY most suitable for?
The ECONO Mare CITY is designed for those who want to turn their daily commute and city errands into a relaxing experience without compromising on top-tier technology. Thanks to the open "low-step" frame, mounting and dismounting is completely unobstructed, which is ideal for riding in city centers with frequent stops.
With an upright posture to prevent back pain and smooth-rolling 28-inch wheels, this bike is the ultimate choice for cyclists who prioritize comfort, reliability, and a natural pedaling feel, while still leaving the door open for occasional trips on well-maintained gravel paths.

What are the differences between the Apes and Mare series and the CITY and SUV versions?
Understanding the ECONO range is easy if we consider the motor architecture and the intended use of the equipment:
Apes Series vs. Mare Series (Rear vs. Mid-drive motor): Apes models use a rear hub motor, which is excellent for flat terrain and casual riding. The Mare series, however, represents a technological leap – it uses a mid-drive motor, mounted in the crank axis. This ensures an incomparably better center of gravity, an exceptionally natural feeling of power delivery, and significantly higher torque (as much as 80 to 90 Nm compared to 45–50 Nm in the Apes series). Mare is therefore the superior choice for hill climbing.
Mare CITY vs. Mare SUV (Intended use):
• Mare CITY: Equipped with a Bafang M210 motor (80 Nm), 9-speed derailleur, smooth tires (Schwalbe Energizer), and geometry that allows for a completely upright posture. It is made primarily for paved surfaces.
• Mare SUV: This is a true all-terrain vehicle. It is equipped with a more powerful Bafang M410 motor (90 Nm), an 11-speed derailleur with a huge gear range (11-50T), aggressive 29" mountain tires (Schwalbe Smart Sam), larger rear brake discs (180 mm), and a more sporty cycling posture.

Bafang M210 mid-drive motor – the heart of your bike
The Mare CITY model is powered by an exceptionally quiet and refined Bafang M210 mid-drive motor (voltage 36 V, power 250 W). The bike provides assistance while pedaling up to the legally permitted 25 km/h (limited).
The biggest advantage of this motor is its stunning 80 Nm of torque and integrated sensor technology, which doses power with extreme precision and smoothness. The system works so seamlessly that you will feel like you have bionic legs – no hill in the city or the countryside will be an obstacle anymore.

Replaceable Comtron battery for worry-free kilometers
Energy is provided by high-quality Comtron ELK smart batteries, which are designed and assembled locally. The series offers complete flexibility, as the batteries are interchangeable.
You can choose between three impressive capacities: 520 Wh (15 Ah), 700 Wh (20 Ah), and 800 Wh (23 Ah). The battery is unobtrusively integrated into the frame, can be locked with a key, and removed quickly. An original Comtron 2A charger (for the 520 Wh version) or Comtron 4A fast charger (for the 700 Wh and 800 Wh versions) is included.

Compact display and intelligent diagnostics
All travel data is monitored via the Bafang DP C080 color LCD display, which is conveniently located next to the left handlebar grip, so you don't have to let go of the handlebars while changing assistance levels. You can choose between five levels of assistance (ECO, TOUR, SPORT, SPORT+, BOOST), or switch the system to level "0" – the motor creates no resistance, and the bike behaves like a regular bicycle.
The system supports Bluetooth connectivity, which means you can view technical details and adjust certain riding profiles via the Bafang Go App on your phone.

Premium comfort: Suspension and Schwalbe tires
To prevent hand fatigue when riding over cobblestones and sidewalks, the front of the bike rests on SR Suntour NEX-E25 Coil 28'' suspension forks, which are proven to absorb urban bumps excellently.
The bike is adorned with premium Schwalbe ENERGIZER ACTIVE PLUS (28x2.0 / 50-622) tires. This model offers extremely low rolling resistance (profile HS427 ENC) and is "armored" with PunctureGuard (50 EPI) technology and TwinSkin puncture protection. All this on durable REVO D rims with reinforced 14G spokes (32 holes).

Hydraulic brakes and 9-speed Shimano drivetrain
Safety must always come first, especially on heavier electric bikes. Tektro HD-M280 2-piston hydraulic disc brakes are responsible for safe stopping. There is a 180 mm brake disc at the front for maximum power and a 160 mm disc at the rear.
Gears are provided by the proven Shimano system. The 9-speed Shimano Altus RD-M2000 SGS rear derailleur in combination with a Shimano Acera CS-HG201 (11-36T) cassette and a strong Shimano CN-HG53 e-bike chain ensures fast and buttery-smooth gear shifting.

Premium urban equipment and ergonomics
The Mare CITY model is characterized by ergonomic perfection. The cockpit with an adjustable stem (ECONO SUV ST286-90B, R:35°, E:90), comfortable handlebars (Width: 680 mm, Backsweep: 37°), ergonomic Velo VLG-1505 grips, and a comfortable Velo VL-6574 seat ensures pain-free cycling even after several hours in the saddle.
The bike is basically equipped for any weather condition. It includes wide PVC mudguards, a massive rear rack (ECONO 29’’ Boost with MIK "Click and go" system), a bell, a sturdy kickstand (40mm mount), as well as a high-intensity front LED light Satelite C19 (DC 8V-58V) and a rear light ECONO WD216.
