Carbon fiber is an amazing material for bikes, but it’s not known as the most environmentally friendly. In order to try and make the build process a bit greener, Flying Machine is introducing their first line of made-to-measure carbon bicycles – the CBL series. Meaning Carbon Based Lifeforms, the CBL 1.0 and 2.0 are the first carbon bikes made in Australia by Flying Machine that offer true custom geometry with a tube-to-tube construction.

Maybe more notable than the addition of the custom bikes to their line up, the CBL series uses plant based epoxy resins rather than the far more common petroleum based resins. Specifically relying on SuperSap CLR which is a product of Entropy Resins, the green option supposedly releases 50% less green house gasses during production and is produced using renewable plant based materials that are co-products or byproducts of other industrial processes.

Found in the frame joints, top tube, seat stays, and chain stays, the plant based resin ‘biocarbon’ isn’t used for the entire frame, but if it performs as needed it seems like a step in the right direction…

The first bike out of the CBL series, the 1.0 uses a one piece top tube and seat stay section mated to a one piece head tube, down tube, and chain stay unit to create a “spring and beam” construction. The upper spring provides the comfort while the lower beam provides stiffness, which sounds similar to the construction ideology of other carbon frame manufacturers.

Equipped with disc brakes and thru axles front and rear, all of Flying Machine CBL bikes are made to order so the one shown above is as ordered by a customer. Base price for the frame starts at $3,979.29 USD – from there, nearly anything can be accommodated which means the sky’s the limit when it comes to the final price tag.

Also available is the second CBL, the 2.0. Built using a more classic road geometry with disc brakes and quick releases front and rear, the 2.0 uses the same Biocarbon construction with Super Sap CLR epoxy resin and Toray T700 UD carbon fiber. Pricing for the 2.0 is a bit less, starting at $3654.45 for the frame and again will full custom geometry and builds available.



  1. Really interested in seeing more sustainable options in bicycles. It’s a factor I give serious consideration to.

  2. Wow, that blue and black bike looks really, really cool!

    But did no one pick up that the seat is tilted down to the tune of about 3-4cm, and just looks ridiculous?

  3. Hmm… I don’t know much about resins and epoxies and such but I wonder about the relative ‘impact’ when longevity is taken into account. For example, the 100 miles less you get from a chain with a plant based lube has a far greater (negative) environmental impact than any gain from using said lube in the first place.

    Also, as someone who’s not an Aussie, the shipping around the world makes buying this for environmental reasons outright ridiculous.

  4. As someone who works in a bike shop down the road from Flying Machine, I can safely say they no nothing about how to actually setup a bike so it works properly… Wrongly indexed gears, rubbing brakes, loose headsets, the works.

  5. I use supersap CPM all the time, and have used many other resin systems over the years. The entrophy resin is good stuff, but there is literally nothing different in the construction process vs typical wet layup (not sure if prepreg is available with it), it is plug and play into any composite production process. SOOOOOOO many companies (the ski and snowboard ones are bad) use this stuff and try to hype it up as “super green” and “eco friendly” yada yada yada, all marketing BS. The big plus is that is much safer to work with in the long run for the people handling it, and that’s it. The ecological impact from composite products is in manufacturing waste and on the tail end in disposal, neither of which entrophy makes any difference, and in fact, Id make a big bet that prepreg construction is much more eco friendly than wet layups due to the reduced waste in layup. Long story short, its a pretty bunk premise to try to start a company on, as there is literally nothing proprietary or new here.
