The Cube Editor Hybrid SLT FE 400X is a high-performance, lightweight urban electric bike that bridges the gap between minimalist design and maximum utility. The "FE" suffix stands for "Fully Equipped," meaning it comes pre-installed with premium integrated accessories including a mudguard-mounted rear light, a heavy-duty carrier, and a sturdy kickstand.
This model is built around a superlight aluminum frame featuring Cube's "Smooth Welding" technique, which creates seamless transitions between tubes for a clean, carbon-like aesthetic. It is powered by the Bosch Performance Line SX motor, which is significantly lighter and more compact than traditional mid-drive units, delivering 55Nm of torque (peaking at 600W). This is paired with a Gates Carbon Belt Drive and a Shimano Alfine 11-speed internal gear hub, offering a virtually maintenance-free, silent, and grease-free drivetrain. Weighing approximately 19.2 kg, it is designed for the modern commuter who values speed, style, and reliability without the bulk of a traditional e-bike.
