Electric bike of the year 2025
The Koga E-F3 6.0 is a high-end urban electric bike, renowned for its lightness and riding comfort. These qualities have earned it the title of "Electric Bike of the Year 2025."
Modern minimalism
The Koga E-F3 6.0 stands out thanks to its combination of modern technology and minimalist design. Its aesthetics immediately catch the eye, or rather go almost unnoticed, as the welds are so discreet thanks to Smooth Welding technology. The complete integration of the cables into the frame reinforces the sleek look.
The KOGA Light Design combines stylish lighting integrated into the headset with an LED headlight mounted on the handlebars. This fully integrated lighting system remains on at all times to ensure your visibility.
This electric bike is powered by a 400 Wh Bosch battery fully integrated into the down tube, combined with the compact Bosch Performance Line SX Smart mid-drive motor and a Gates belt drive. The Smart System allows full connectivity with the Bosch eBike Flow app, through which you can customize assistance modes and receive over-the-air updates.
Thanks to the Enviolo continuously variable gear system, you benefit from a wide range of gears, ideal even on hilly terrain, without sudden changes in cadence. The minimalist Bosch Purion 200 display, mounted on the handlebars, ensures simple and intuitive control. In this configuration, the Koga E-F3 6.0 has a total weight of approximately 22.4 kg.
Highlights
Thanks to its relatively low weight, the Koga E-F3 6.0 is particularly maneuverable and remains pleasant to ride even without assistance. The Enviolo system allows for intuitive and smooth gear changes. The combination of a Bosch motor and belt drive is reliable and virtually maintenance-free.
The Koga Feathershock suspension fork subtly absorbs even the most pronounced irregularities without causing a pumping effect when starting off. Shimano hydraulic disc brakes guarantee powerful and safe braking. Design enthusiasts will also appreciate the sleek lines, internal cable routing, and neat integration of the motor and battery.
Weaknesses
The main drawback of the Koga E-F3 6.0 remains its limited range. The 400 Wh battery is smaller than the 500 Wh or 625 Wh versions commonly found on heavier trekking bikes, which reduces the maximum distance per charge.
Quality comes at a price, and this model confirms its position in the upper segment. Finally, despite its marketing positioning as a "hybrid" model, the fairly upright driving position seems less sporty than one might expect.
