Sirrus Men Ss

Sirrus Men Ss


We understand that fitness bikes can get a bad rap. Most of the time, they err on the side of value over performance, which leaves YOU feeling in between, and frankly, a little burned. But we're happy to say that our Sirrus is out to change that by providing the perfect blend of everyday efficiency with the performance you need to hit your fitness goals at speed. This Sirrus was designed for the ultimate ease of use, which is why it has a single gear that removes all the fuss and maintenance of shifters and derailleurs. No need to worry about shifting, just hop on and start cruisin'. And while you’re at it, the comfortable Body Geometry touchpoints are sure to take the sting out of long rides, while rack and fender mounts give you the option to lug your stuff around town on the bike instead of on your back. *While this frame platform was designed from the ground up for all riders, some of the models feature gender-specific touchpoints.
  • A straight blade steel fork provides a responsive ride, while the fender and rack mounts give you the option to install fenders and racks that can keep you dry and transport your gear around town.
  • Body Geometry touchpoints take the sting out of riding with their ergonomically designed, scientifically tested shapes.
  • Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency. The A1 SL Premium Aluminum construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
