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.

S40 Complete Components
The 2021 S40 Complete is outfitted with a SRAM Apex 1x11 system we chose for performance. The 42 tooth chainring with an 11x42 cassette hits the sweet spot for power on the flats and gearing for the climbs. Plus you get all the benefits of a 1 x system: plenty of gearing with lower maintenance and less to go wrong.

|Thru-Axles||The latest in high-end cycling axles attach the wheels more securely, are stiffer and flex less than their quick release predecessors, resulting in better power transfer and more resilience. For the new thru-axle on the S40 we chose a sleek, leverless style that even houses its own internal removal tool for the axle itself and brake rotors.|
