Cube EDITOR HYBRID PRO 400X

Lightness above all. The Bosch CompactTube 400 Wh is the battery designed for bicycles where every gram counts. With 400 Wh of capacity in a deliberately compact format, it is aimed at cyclists who favor the agility and maneuverability of a light bike, without giving up electric assistance on a daily basis. Its reduced format allows discreet integration into thinner frames and sportier geometries - where a standard PowerTube could not find its place. Ideal for urban outings and short to medium distance journeys, it offers most of the autonomy in the most compact format in the Bosch range.

The cassette built to survive an electric bike. The Shimano CUES CS-LG400 in 11-50T is an 11-speed cassette built around LINKGLIDE, the technology Shimano developed specifically to answer the problem e-bikes create: a motor that delivers torque constantly wears a drivetrain out far faster than a human leg does. In practice, LINKGLIDE claims up to three times the tooth life of a conventional Hyperglide cassette under high chain tension. The teeth are thicker and the shift ramps redrawn to absorb shifting under load — the kind you make without thinking mid-acceleration, motor at full assist, and which destroys an ordinary drivetrain. Shifting is also smoother in both directions, with noticeably less shock through the pedals. With an 11-13-15-17-20-23-26-30-36-43-50 progression, it covers the ground without gaps: closely spaced ratios at the bottom of the cassette to hold a steady cadence on the flat, and a 50-tooth sprocket so you are never stuck on a climb, loaded or not. It requires a LINKGLIDE drivetrain (matching CUES derailleur and shifter) and takes either a LINKGLIDE or an HG 11-speed chain.
