BMC Alpenchallenge 01 ONE S Alfine 8 Hybrid Bike 2021
The BMC Alpenchallenge 01 ONE S Alfine 8 Hybrid Bike blends function and form to offer itself as the ideal partner for town errands or social weekend rides.
The frame is made from a high grade of alloy, and this affords reactive acceleration, robustness and low weight. Partnering the frame is the carbon fork, and this works in tandem with the frame’s dropped seatstays to cushion road imperfections, reduce surface vibrations and lower rider fatigue on longer trips. A racing bike inspired geometry gives nimble and responsive handling properties that are ideal for when rushing about town while light but robust wheels are spritely and dependable across all manner of road surfaces.
The Shimano Alfine 8-speed hub gear and belt drive system is ideal for a busy city schedule as it is durable and low maintenance and hydraulic disc brakes stop abruptly but with control when confronted with heavy traffic. Included mudguards keep the rider and bike shielded from road spray when tacking wet conditions and lights that are integrated into the handlebars and seatpost increase safety after dark.
