Cruzbike Q45 Tech Specs and Fit

Frame

Unique swing arm design allows the Q45's robust aluminum frame to run a super smooth suspension system and pack down for travel.

    Front Triangle

    Cruzbike's patented race-proven dynamic boom drivetrain is the engine of the Q45 recumbent touring bike. The same system that powers our performance bikes to records and wins now powers the Q45 so you'll be able to take on whatever mountain range is on your bucket list, while hauling all your gear.

      Suspension System

      The Q45 frame accommodates a full-size (165 mm) shock. This delivers excellent ride quality with the stock coil shock, and also allows riders the option of upgrading to an air shock. The stock shock is fantastic and blows open the terrain upon which the Q45 thrives. Mixed surfaces on that trip you're dreaming of doing? No problem.

        Adjustable Seat

        The Q45's two-piece aluminum seat is ergonomically designed for comfort for riders of all shapes and sizes. The cushion is a one-piece dream that cradles its rider from shoulders to derriere. The seat back angle is also adjustable from 30-degrees to 53-degrees so you can get your backrest dialed in just the way you like it.

          Racks and Bosses

          The Q45 is designed for hauling gear and mounting accessories. It boasts 8 threaded mount points on each side and one in the middle under the down tube plus a dedicated fender mount. Load up panniers, mount lights, install fenders - anything you need for your adventure - this bike can handle it.

            Fit

            The Q45 fits riders with an X-seam between 34" and 46" (approximately 5'1" to 6'3"). The cockpit of the Q45 is a little tighter than the T50 or the S40, so if you are taller than 6'3" or weigh more than 200 lbs, it may not work for you. If you are close to the outside of the fit range, please contact us at support@cruzbike.com.
