PERFORMANCE WITHOUT COMPROMISES Whether it's the frame, drive system, suspension, or wheels - the Sonic EVO AM 4 Carbon makes no compromises. Equipped with the Sonic E-Power chassis made of carbon, it provides the optimal foundation for the power of the Bosch Performance Line CX drive, available with either a 625 or 750 Wh PowerTube battery. This makes even the steepest climbs manageable. The RockShox suspension with 150 mm travel ensures optimal responsiveness and maximum flow during descents. Another highlight is the high-quality MAVIC E-Deemax wheels paired with the grippy SCHWALBE tire combination of Magic Mary and Big Betty.
