Green technology Wood was originally used to make bicycle frames but was replaced by stronger materials like carbon fiber and titanium. However, manufacturers have now started using wood combined with technology again for bicycle frames. The Axalko BAT frame uses a micro-laminated wood structure combined with advanced glues and resins to create a frame that is both lightweight and resistant through an optimized strength-to-weight ratio. The frame is handcrafted to attention to detail while maintaining technical specifications.
