Bosch PowerMore 250Wh Range Extender

£420

The Bosch PowerMore 250Wh Range Extender bolts onto the bottle-cage mounts of compatible Bosch Performance Line and Performance Line CX-powered bikes, adding around 250Wh of extra capacity for longer days out without needing to carry a spare battery or plan a ride around a single charge. It's designed to work alongside the internal PowerTube battery already fitted to your bike, extending typical assisted range by a meaningful margin on higher support settings. Installation is straightforward on any Bosch-compatible frame with the right bottle-cage spacing — check with us before ordering if you're not sure your specific model supports it. A sensible addition for anyone regularly riding longer routes, bikepacking trips, or big vertical days where running out of assistance partway through is a genuine concern, rather than an occasional inconvenience.
