A range of up to 55km is perfect for local trips and longer weekend rides. A suspension fork with 63mm of travel is paired with wide 45mm tyres to provide comfort over rough roads, and the capability to head off the beaten track on towpaths and gravel tracks. Finished off with full length mudguards, pannier rack and lights the Arcus 2 is a true modern utility bike.
