Introducing our newest recumbent bike in the Cruzbike lineup: the S40. This is a versatile road bike with a more upright backrest angle than both our our record-setting V20 and its predecessor, the S30. It is equally at home in the flat lands and in the mountains. The S40 uses the same power train as the V20, except we have widened the fork crown to accept larger tires. Configure the S40 as a fast road bike, an adventure/endurance bike, a sleek and sophisticated tourer or the ultimate commuter.

Buying Options

US customers may order the S40 complete as featured. The complete option includes all main components installed in the frame, pre-fit to your measurements. The installation includes shifters, brakes, main cable housing and grip tape. The drive wheel includes the cassette pre-installed. The S40 may also be purchased as a frameset for $2299.

The S40 is built for adventure. You can load it up with under seat and rear racks and panniers for bike packing adventures on the open road.


Choose bright bold orange, green or blue graphics accent colors on the S40's slate frame or opt for classic light gray accent.


Works with a wide variety of component sets and riding styles:
-Configure the S40 as a fast road bike with high end components and skinny 700 C tires.
-Or as an adventure/endurance bike with fatter tires and wide range gearing that will handle any road, even if it's not really a road,
-Or as a sleek and sophisticated tourer carrying everything you need for days on the road
-Or customize it with exactly what you need to be your ultimate commuter.


The adjustable front boom is stiff and light, allowing for customized positioning of feet and handlebars.


The S40’s mainframe is a light, strong and beautifully curved hydroformed (HF) aluminum tube. The hydroforming process delivers a frame that has a high stiffness to weight ratio. The result is a stiff frame that is very smooth on the road.


The S40’s seat is made of lightweight carbon fiber and fits the frame contour delivering maximum power transfer efficiency. The position of the seat extension can be adjusted for comfort. The recline angle is 40 degrees


The included headrest is fully compatible with all V20 headrest accessories make. Some riders may also prefer the neck support for endurance rides.

Performance road recumbent bike - S40 by Cruzbike


Cruzbike combines the best features of traditional frame road bikes with the aerodynamics and comfort of fixed boom recumbent bikes. This technology puts performance and ergonomics in the same bicycle. The core of the drive system is Cruzbike's unique dynamic Boom Front Wheel Drive. The advantage of Dynamic Boom Front Wheel Drive is the linkage of the upper and lower body across the drivetrain as it rotates around the axis of the head tube.

This linkage allows you to boost power when climbing or sprinting by engaging the upper body in much the same way as standard diamond frame riders do when they climb or sprint. Every other production recumbent bicycle in the world has a fixed-boom. Cruzbike has learned through many years of research the best implementation of Dynamic Boom Front Wheel Drive technology.
