We are excited to offer our customers the opportunity to experience the exceptional quality and performance of OPEN Cycle bikes and become part of this exciting new movement in off-road cycling.


With the U.P., Open Cycles pretty much started a new category…. Road bike speed combined with go-anywhere capabilities opened up (as it were) the off-road world to a new breed of cycling enthusiast. Continued innovation and updates such as increased tire clearance, ability to run multiple wheelsets and improvements to the geometry have kept the Open U.P. unstoppable on tough terrain, yet fast and comfortable on the road. Exceptional comfort and unparalleled versatility.


Love the idea of the Open U.P. but want to shave even more weight? Meet the Open U.P.P.E.R. Weighing in approximately 180 grams lighter than its U.P. sibling, the U.P.P.E.R. retains the same geometry, stiffness, tire clearance and durability. Open has simplified your color selection as well, offering the U.P.P.E.R. in black and ready-to-paint variations. A fly-weight, go-anywhere bike perfect for mixed surface rides and most gravel routes. Set it up with 650B’s and wide tires and you’ll be flying across very tough terrain, as well as pavement.


The Open WI.DE. takes up the mission of the Open U.P., and broadens the horizon. The Double Drop chainstay design brings increased clearance for larger tires (even on 650B wheels), increased BB stiffness and reduced weight to top it off. The WI.DE. maintains the nimble, versatile geometry of the U.P., allowing you to conquer just about any terrain you might find, without slowing you down on the more straightforward roads and trails. Push the boundaries of what you’ve always thought a drop-bar bike can do.


In conceiving the Open MIN.D, which stands for “MINimal Design”, the company’s founders had one mission in mind (or MIN.D, if you prefer): to create the road bike that they themselves wanted to ride. Nothing more, nothing less. The MIN.D encompasses both the classic road bike aesthetic and the unique brand of envelope-pushing that Open Cycles is famous for. A remarkable blend of performance and comfort. Embrace the open road with the Open MIN.D.

OPEN MIN.D. California

Open Cycle’s outstanding pure road bike, the MIN.D, is available in two variations. The MIN.D California is virtually identical to its standard sibling, but made here in the U.S.A at Open’s Project California Facility. Besides its local origin, the MIN.D California differs in its weight (75 grams lighter) and stiffness in all directions except in the continuous seattube, where it actually provides even more flex than the standard MIN.D. The resulting combination is something special and unique in a sea of mass-produced carbon bikes.


With its roots set in high-performance XC riding, the Open ONE+ is a purist’s hardtail, for those who enjoy the associated challenge, precision and razor-sharp handling that come along with it. Able to be set up with 29” wheels, or 27.5” with up to a 3” tire, the ONE + offers versatility to go along with it’s laser focus. Using a blend of high and low modulus carbon in the constriction, the ONE + dishes up a beautiful riding frame, designed to be ridden hard and ridden fast.
