Factor O2 Miami Blue Complete Bike

Redesigned from the inside-out utilizing the revolutionary manufacturing methods of the O2 VAM, the second generation of the O2 is stronger, lighter and packed with class-leading technology.

Available as a frame, fork and headset package here.

Redesigned From the Inside Out

Utilising industry-leading technology learned through the O2 VAM project, the second generation of O2 is lighter, stronger and more comfortable than before. Pressurization greater than normal in the manufacturing process removes excess resin, making O2 carbon stronger, lighter and more efficient.


Confidence, Control and Comfort
Versatility is achieved through geometry specifically optimised for consistent handling across all sizes. Rear mechanical trail increases along with front trail in a linear fashion reflective of the higher centre of gravity of larger sized riders. The second-generation O2 also features larger tyre clearance of up to 30mm wide (measured).

Factor O2 Reviews

“The sweetest, quickest, most beautiful bike I have ridden. It’s not one to meander around on, it goes when you want it to and when it goes it’s quick and surprisingly forgiving over quick, long rides. What else to say other than I am in love with it!”

Factor O2 Reviews

“A fantastic handling bike, comfortable enough to ride 11 hours in Leige-Bastogne-Liege in horrendous weather, yet still feel like the top end race bike it is. Clearance for 28mm tyres on a rim brake frame is fantastic – it’s hard to fault. Very comfortable for a true race bike, position can be aggressive or a bit more relaxed if required (easy to change the set up). It’s the best handling bike I’ve ever ridden and it inspires confidence on descents and corners.”

“Great frame, stiff, but with no road buzz, was expecting it to climb well but it does everything well! Bought because of build quality and design.”

Factor O2 Reviews

“The O2 is a true wolf in sheep’s clothing. A classically styled road bike, stunning performance; stiff and responsive! Overwhelmingly happy with it! The power transfer through the bottom bracket is incredible, you can really sense the design and engineering here when you put the power down. A good experience, great customer support with friendly staff at Factor UK. The whole experience leaves you feeling you have the perfect tool for any ride, even if the legs are sometimes lacking.”

I can honestly say that the Factor bikes (both the O2 and the One) are hands down the best bikes I have ever owned! Amazing handling, feel and comfort). They just seem more responsive, faster, they look amazing and just feel better than anything else.”
