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 emphasises 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. It's a real mountain bike that's also perfectly suited to daily commutes, rides around campus or just getting from A to B on any surface.
NOTE: The helix is in between sizes of a Trek, so the XS size is in between XS & SM of a Trek etc... etc... This bike is very similar to a Trek Marlin 5!
