Take on any distance road event. Stack long days. Eat more bugs. The Cruzbike S40 endurance road bike is designed for the cyclist who wants to ride farther and train longer. Our patented, race and record-proven geometry changes the rules of cycling: now, comfort in the saddle doesn't come at the cost of performance.

Cruzbike S40 2021 Recumbent Bike Tech Specs and Fit


Lightweight, road-smoothing hydroformed aluminum frame. The S40 recumbent road bike's wheelbase, trail, and head-tube angle deliver smooth handling, natural cornering and a responsive ride whether you are descending at top speed or navigating twisting back roads.

    Front Triangle

    The famously stiff patented drive system that vaults Cruzbike racers to records and wins, powers the S40 recumbent road bike. It shares the stiff, efficient drive geometry of traditional road bikes and transforms performance cycling technology into an incredibly fun, liberating cycling experience. It also makes Cruzbikes the fastest-climbing recumbent bike in the world.

    This patented drive system not only frees us from the long, inefficient chains and special parts fixed-boom recumbent bikes require, it links the upper and lower body across the drive train as it rotates around the axis of the head tube. This linkage allows Cruzbike recumbent bike riders to increase power when climbing or sprinting by engaging the upper body in much the same way professional cyclists do when they climb or sprint on traditional road bikes.

      Seat-to-Frame-to-Drive Connection

      The Cruzbike S40's carbon fiber seat fits the curve of the frame so that no watt is wasted. As you press your back into the frame, you engage your whole body through the handlebar and cranks. Energy surges through the drive system and powers the bike forward, leaping up hills or accelerating into a sprint.


        The 2021 Cruzbike S40 fork is designed to accommodate a range of setups from fast endurance road to plush Roubaix-style adventure with beefier tires. Plus clearance at the crown for fenders and wide tires is massively improved on the 2021 S40. The product team chose the tough, versatile Maxxis Re-Fuse 700x32c tire for the S40 Complete 2021 for its versatility and performance so you can ride whatever road is calling your name, day after day.

          Racks and Bosses

          The Cruzbike S40 is the machine for fast commuting, multi-day rides, brevets and tours. Possibilities abound when your recumbent bike is fast, light, comfortable and ready to be outfitted for the demands of your cycling ambitions. The frame boasts threaded mount points for racks, panniers, lights, fenders and hydration.
