Begin your fitness adventure. The Specialized Sirrus is a women’s specific hybrid sports bike that offers confident performance on roads and cycle paths – ideal for urban cycling and commuting as well as fitness training.
Getting fit is hard enough without emptying every last cent in your wallet for the tools to do it with. Never fear, though, because our Women's Sirrus was designed to be your partner in all things fitness at a price that won't leave you broke and hungry.
Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency. The A1 Premium Aluminium construction is plenty durable, while the rack, fender, and disc mounts give you an incredibly versatile package.
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 labour-intensive maintenance to have awesome stopping power.

As cyclists ourselves, we know you will be keen to get out on your new bike as soon as possible. That's why we provide you with all the essential kit you need to get your shiny new bike rolling for the first time.
Most bikes don't come with pedals as standard so we include a set of basic pedals, free of charge with every bike we send out. We will also provide you with a pedal spanner to fit them and a 9-key trail tool, along with full instructions for setting your bike up out of the box. Each bike is sent out with a 16 point, quality control check sheet so you can be confident that your bike has been fully checked by our qualified mechanics.
All these items are provided at no extra charge and are packed into a Tredz drawstring bag that doubles up as a handy backpack for carrying your ride essentials.
