Powerful BHZ motor and 630 Wh capacity
At the heart of the bike is a lightweight and compact BHZ by SEG motor, paired with a high-capacity 630 Wh battery. This combination provides a range of up to 150 km and delivers natural assistance precisely when the road rises into a steep climb.
Clean aerodynamics and fully integrated cable routing
The Race Alloy frame, combined with the full-carbon BH iRS1 Carbon ACR fork, utilizes the advanced ACR cable routing system. All cables are hidden inside the stem and frame, ensuring not only a sleek, minimalist look but also lower aerodynamic drag.


Reliable shifting and braking performance with Shimano 105
The drivetrain features the proven Shimano 105 road groupset in a 2x12-speed configuration (11-34T cassette, FSA 50/34T chainrings). Shimano 105 hydraulic disc brakes with 160mm rotors provide absolute confidence and perfect braking control during fast descents.
