BMC 257 AMP AL ONE ST Disc Electric Hybrid Bike

Bring a boost to your urban rides with the BMC 257 AMP AL ONE ST Disc Electric Hybrid Bike. With tuneable suspension from the ICS MTT x Redshift suspension stem, comfort is dramatically enhanced, and the premium aluminium frame and fork are strong and durable thanks to the powder-coated finish. A step-thru frame makes the bike easier to mount and dismount.

Power is delivered by a Bosch battery and motor system that provides pedalling assistance up to 15.5mph (25km/hour). Engagement is smooth for a natural ride feel. Hydraulic discs ensure confidence-inspiring stopping power, and the Shimano Alfine 8-speed hub gears with belt drive deliver a range of gears and are low maintenance. The bike rolls on well-built wheels fitted with Pirelli Angel GT in a 37mm width, for bump-smoothing comfort, grip and puncture protection. 

The bike is well equipped for all-condition riding, supplied with mudguards that have an integrated luggage rack, along with good quality lights and a kickstand.
