ECONO Apes CITY 28 EER4
Meet the new ECONO Apes CITY 28 EER4, Model 2027, a compact and comfortable electric bike designed for urban mobility, everyday commuting and delivery services.
Powered by a Bafang H305 rear hub motor with 250 W and 50 Nm of torque, it provides smooth and reliable assistance for city riding and longer daily routes. The Schwalbe 28 × 2.0" tires, combined with an 75 mm front suspension fork, provide excellent stability and comfort, even on rough asphalt, cobblestones, and also gravel.
Power is supplied by a reliable COMTRON ECONO battery, developed and assembled in our own facility according to high quality and safety standards. For the 2027 model range, it is available in two capacities:
- 600Wh and
- 800Wh.
Both batteries are fully removable and compatible with all ECONO 2027 models, allowing them to be easily swapped between different bikes and providing maximum flexibility for everyday use.
The C080 full-color display provides a clear overview of essential riding information and allows easy control of the electric assistance directly from the handlebar. You can choose between five assistance levels: ECO, TOUR, SPORT, SPORT+, and BOOST.
The Apes CITY 28 EER4 is equipped with Shimano MT-200 hydraulic disc brakes, a Shimano 9-speed drivetrain, a practical MIK-compatible rear carrier, and a adjustable handlebar stem.
The ECONO Apes CITY 28 EER4 is ideal for riders looking for a comfortable, stable, and practical everyday e-bike. It is also a great choice for professional delivery riders such as Wolt and Glovo couriers, especially with the 800 Wh battery, as well as for anyone who appreciates the distinctive look, stability, and comfort of a city e e-bike.
With its compact dimensions, powerful assistance, high-capacity COMTRON battery, and practical equipment, the Apes CITY 28 EER4 is ready for everything from daily city rides to demanding everyday use.
