Sustain-a-bike
- Sustainabike - a work in progress
The aim of this personal project is to design a mass-manufacturable, sustainable, and cheap bicycle. As this is a work in progress images and video will be added at each stage (newest at the top) showing development.
If you have any positive criticism, ideas, feedback, or input, please get in touch via the contact page. 
Early stages of CAD modelling in which the geometry and parameters are defined. With the basic concept worked out, technical details and complexities are now worked out. This is still very much in concept development stages.
Early bottom bracket junction (top) and assembly layout with draft lines (bottom).
Simple card model to test one of the main principles of the design to use 4 main triangles (above) and the parts laid out (below)
Details: Seat-post junction (top left) and ideation sketching of junction reinforcement details (rest of sheet). Different reinforcement shapes would give different characteristics, better strength/stiffness or better tyre clearance, etc.
Details: This bike isn't designed to look like a bike made out of wood in a shed, its designed to look and ride like a real bike. To do this, all the joints and junctions must be strong and durable, yet unobtrusive.
Early drawing of a complete assembled frame concept (left) and basic exploded diagram (right).
Headtube construction top view (left) and assembled headtube junction (right). Note shaped ends of wood to blend into tubing.
Ideation sketching exploring frame form, construction, and assmbly. This concept would use bent plywood and only 2 main pieces of plywood. Top view assembly (left), complete assembly (middle), bottom bracket example junction (right), early exploded view (bottom).
Getting the idea on paper before its forgotten: Initial ideation sketching. Shape (top left and bottom left), and construction using finger joints (right). The use of finger joints was written off early on as it would over-complicate the design. Integrating the tubing into the wood was explored here, idea that would stay.
