Engine Performance

The ECONO Apes EER4 is powered by a Bafang H400B rear hub motor delivering 250 W of nominal power and up to 40 Nm torque. Mounted in the rear wheel hub, this design provides direct power transfer, ensuring responsive acceleration for urban riding and flat-terrain cruising. The motor works in combination with a cadence sensor, which activates assistance smoothly when pedaling begins, making it intuitive and beginner-friendly. Its 36 V architecture supports efficient energy consumption, extending ride range without compromising performance. With a compact and lightweight design, the H400B minimizes added weight to the wheel assembly while maintaining durability and low maintenance needs. Optimized for city commuting, recreational cycling, and relaxed touring, this motor provides a balance of simplicity, reliability, and efficiency for everyday e-bike use.

Battery Endurance

The ECONO Apes EER4 is equipped with removable ECONO ELK batteries in three capacities: 520 Wh (15 Ah), 700 Wh (20 Ah), and 800 Wh (23 Ah). Depending on configuration, the e-bike delivers up to 160 km range under optimal conditions. The batteries are interchangeable across the 2025 ECONO model line, offering flexibility for owners with multiple bikes. For charging, the 2 A charger is paired with the 520 Wh version, while the 4 A charger supports faster replenishment of the 700 Wh and 800 Wh packs. Reinforced housing within the 6061 aluminum frame ensures secure integration, vibration resistance, and easy removal without tools. The battery management system provides cell balancing and over-voltage protection to extend service life. With versatile capacity options, the Apes EER4 guarantees long-lasting endurance for city commutes and leisure cycling.

The SR Suntour NEX-E25 suspension fork with 75 mm travel absorbs impacts, improving stability and rider comfort on uneven roads. OBOR Mambo E25 28×2.0 tires provide traction, puncture resistance, and durability for city terrain. Integrated LED front and rear lights improve visibility and extend operational safety during low-light conditions. A MIK-compatible rear rack allows secure and easy attachment of accessories, enhancing practicality while maintaining safe load distribution.

  • Comfort & Design

    The ECONO Apes EER4 is engineered around a 6061 aluminum alloy frame designed for lightweight strength and corrosion resistance. A city-style geometry with an upright seating position reduces rider fatigue, while the adjustable stem (0–90°) and ergonomic 680 mm handlebars allow a customizable fit. The Velo VL-3644 saddle and 30.9 mm seatpost provide wide, cushioned support for longer rides. At 22.6 kg (without battery), the EER4 maintains easy handling for storage and transport. The Bafang DP C080 side-mounted TFT display provides clear data visualization, including five assistance modes: ECO, TOUR, SPORT, SPORT+, and BOOST. Integrated blatniki (mudguards), kickstand, and MIK-compatible rear rack add everyday convenience. With its clean design and functional ergonomics, the Apes EER4 balances comfort, utility, and performance for daily commuting and relaxed leisure rides.

  • Maintenance

    Routine maintenance of the ECONO Apes EER4 ensures reliable long-term operation. Tires should be checked regularly for pressure and tread wear, with replacement intervals guided by mileage. The hydraulic braking system requires inspection of pads, rotors, and fluid levels to maintain stopping performance. The Suntour suspension fork should be cleaned after dusty or wet conditions, with seals inspected for leaks. The Shimano Altus 9-speed drivetrain requires regular cleaning, lubrication, and indexing checks to ensure smooth shifting. Electrical connectors and the Bafang C080 display should be kept free of dirt and moisture. The removable ECONO ELK battery should be stored at 40–60% charge if unused for extended periods, in a cool and dry environment. Regular tightening of wheel axles, stem bolts, and rack fasteners maintains frame stability. With scheduled care, the EER4 remains efficient, comfortable, and durable for years of everyday cycling.
