2025 Polygon Kalosi Miles High Step — an electric hybrid bike built for effortless city commuting and weekend escapes. Pedal-assist power meets an upright, comfortable geometry so steep hills feel flat and long distances feel quick.
The Kalosi Miles pairs a rear hub motor with a torque sensor for smooth, intuitive assist, a front suspension fork with high-volume 700C tires to soak up potholes and cobblestones, and Shimano hydraulic disc brakes for confident stopping power in any weather.
