Cruzbike A4x Key Features
-
Dynamic Boom Front Wheel Drive — Cruzbike's patented, race-proven drivetrain engages upper and lower body for powerful climbing and efficient cruising, even under a full touring load
-
Dual-position, tunable suspension — choose progressive (forward position) or linear (rear position) shock behavior to match your terrain and load; adjustable spring preload adds fine-tuning for rider weight and carry load
-
Rearward suspension pivot — pivot sits behind the rider rather than underfoot, eliminating the vertical bounce of earlier designs for true off-pavement composure and confident tracking through technical terrain
-
Croder SPIRIT modular crankset — lightweight, precision-engineered crank system with interchangeable arm lengths, spiders, and chainrings available directly through Croder; stock spec: 155mm arm, 24mm axle, DM42T chainring (6mm offset), BSA24 steel bearing bottom bracket
-
Adjustable seatback angle — dial in your riding position between 44 and 77 degrees for the terrain ahead on the A4x's compliant, comfortable resin seat.
-
Adventure-ready rack and bag compatibility — extensive mounting options for panniers, frame bags, handlebar bags, and more; configure your carry system for any mission
-
Purpose-built off-pavement frame — new heavy-duty chassis engineered for trail, gravel, and mixed-surface touring with the structural integrity to handle loaded adventure riding
-
Recumbent ergonomics — full-body comfort eliminates the wrist, neck, shoulder, and saddle pain that ends adventures early on traditional bikes
-
Generous tire clearance — stock 650b wheels accommodate tires up to 57mm (2.25") wide; swap to 24" wheels and clearance opens up to 68mm (2.6") for even more capable rubber on demanding terrain. Note: fender installation is not compatible at maximum tire width.
-
Robust kickstand mount and stock single kickstand — the beefy and adjustable kickstand that comes stock with the A4x Complete will work for the 650b stock wheels and 24” conversion. This is really good for parking a fully-loaded bike when you pull off for a coffee. Plus, this mount is also compatible with a double kickstand for those who prefer that setup.
-
Packable for air travel —disassembles to fit inside the Tern Airporter Slim hard-shell case (with 24" wheels) at standard checked luggage dimensions, making international and fly-to-ride adventures genuinely practical
A4x Adventure Touring Recumbent Bike Complete Components
For the A4x recumbent touring bike we upgraded to thru-axles, flat mount brakes and more. We chose 1x11 MTB components that balance performance, durability and value. This setup is designed to thrive even with a fully loaded A4x.
