If you ride for fitness then you'll be looking to move and move efficiently, nothing wants this more than our Sirrus. With an all kill, no fill design, the Sirrus offers everything that you need and nothing you don't. We've built this bike using durable components to last years of daily use, a lightweight A1 Premium Aluminium frame that's corrosion resistant and our comfortable Body Geometry components for enjoyable long rides.

Built around a strong A1 Premium Aluminium frame, the Sirrus features rack and fender mounts so you can carry your gear and avoid road spray in the wet weather.

With V-brakes you can rely on optimum stopping power and with the easy maintenance without the need to bleed or endure labour-intensive care.

  • The reliable and sturdy A1 Premium Aluminum frame features rack and fender mounts, allowing you to carry gear or to fend off road spray in inclement weather.
  • A steel, straight blade fork provides a responsive ride, while the fender and rack mounts give you the option to install rain-fighting fenders and racks that can transport your gear around town.
  • V-brakes are dependable and easy to maintain, so you won't have to worry about brake bleeds or labor-intensive maintenance to have awesome stopping power.
