Building great recreational-level bikes that ride much like our high-end bikes is a passion at Jamis. No bikes showcase our commitment to do just that better than these. The Helix chassis emphasizes all-day performance with quick, but not overly twitchy handling attributes. Make no mistake though, if you want to throw down they’re more than able to keep up.
