The Cube AMS Hybrid ONE44 C:68X SLX 400X is a revolutionary lightweight e-MTB designed for riders who prioritize agility and a "natural" bike feel over raw motor torque. By utilizing Cube's top-tier C:68X carbon (their lightest and stiffest layup), it achieves a total weight of approximately 17.3 kg, making it significantly easier to flick around on technical trails compared to full-power e-bikes.
For 2026, the SLX model features a high-performance build highlighted by the Bosch SX motor and a premium Shimano XT Di2 electronic drivetrain. It is an ideal choice for fast-paced trail riding where the rider wants to work with the motor rather than just being carried by it.
