HBSA: HTech Bikes
HTech Bikes makes bicycle frames from a combination of wood and carbon fiber. Glenn Mountain talked to the company at the Handmade Bicycle Show Australia, on April 29.
How did the company start?
The company started professionally in 2016. Hayden, who builds the frames, needed a project for his high school woodworking class and suggested a bike to his teacher. The teacher said it wouldn’t work, so when Hayden finished school he said he was going to do it. And he did. Backed by his family, he has been building bikes and a reputation for over two years.
Purpose and inspiration for the bike
A love of woodworking and the challenge of building frames with natural materials.

Frame material and component choices
The Aeriform is southern mahogany but Hayden also uses jarrah, marri and blackbutt from Western Australia. We take into account the strength-to-weight ratio of the timber. The best have long grain and interlocking fibres which give torsional stiffness in areas like the bottom bracket whilst still having the compliance of timber. Carbon sleeves are inserted in head tubes and bottom brackets, bonded to aluminium machined cups.
The Juncture, a hybrid, is a mix of jarrah and carbon tube construction. It's built using the same technology and processes we developed, but in a more economical package to produce the lowest cost wooden bike on the market.
The Juncture with its carbon/wood mix is the economy model
Design challenges and features
38 interlocking pieces are roughed out with CNC then hand finished and epoxied together. You can see the design of the joints used Isoloc joints, as opposed to typical finger joints. This makes a quite attractive feature with the timber while adding strength and more design freedom. Also, we use a Selective Carbon Reinforcement process developed by ourselves to reinforce the walls in place of more common aluminium.
