Belgie AIR

Our custom-built road frame utilises 3D printing technology in collaboration with Bastion Cycles. Limited edition release.


The Belgie series of road bikes was designed to bridge the gap between race and endurance. 

In 2018 Curve Cycling celebrated five years in business, and Steve Varga (Curve’s co-founder) turned 40. Steve decided to celebrate these milestones by designing the finest realisation of our Belgie. He wanted to explore innovation, showcase Melbourne cycling culture, and, of course, have the best 40th birthday present ever.

The AIR is our ultimate Belgie, which celebrates sophisticated artistry, performance, and a bike for those wanting something elegant and decorative.
