Building great recreational-level bikes that ride much like (and look a lot like) our high-end bikes is a passion at Jamis. And, no bikes showcase our commitment to doing just that better than the Helix. This bike's chassis emphasizes all-day performance, and the handling is quick and sure without being overly darty. But make no mistake, if you want to throw down, they are more than able to keep up with their 27.5" wheels, precise shifting drivetrains, and incredibly powerful disc brakes.
