Unique swing arm design allows the Q45's robust aluminum frame to run a super smooth suspension system and pack down for travel.
Cruzbike's patented race-proven dynamic boom drivetrain is now the engine of the Q. 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.
The Q45 frame got a redesign to accommodate a full-size (165 mm) shock. This simple change dramatically improves the 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.
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. Load up panniers, mount lights, install fenders - anything you need for your adventure - this bike can handle it.

The Q45 fits riders with an X-seam between 34" and 46" (approximately 5'1" to 6'5"). Riders over 6' with an x-seam longer than 42" may need a longer slider. Head over here to learn how to measure your x-seam.
If you need a longer slider reply to your order confirmation email with a note that your x-seam is over 42" and we'll put the long slider in the box for you. If you are shorter than 5'4" contact us at firstname.lastname@example.org. Depending on your leg length, you may want slightly smaller wheels so that you can stand over the seat easily.
