Overview
About this bike
Building great recreational-level bikes that ride much like (and look a lot like) their high-end bikes is a passion at Jamis. And no bikes showcase that commitment better than the Helix A2. The Helix chassis emphasizes all-day performance with handling that’s quick and sure without being overly darty. Its suspension fork and 21-speed drivetrain make it trail-ready and quite capable, while disc brakes help ensure safety and control wherever you ride, and in all weather. You don’t have to give up comfort for capability, though, and the Helix A2 provides both, offering a women-specific saddle, riser bar, and soft, Kraton grips, all with a heads-up geometry that keeps you riding comfortably all day long.
