Mission Statement
• To design and construct a low cost, reliable, and desirable bike frame compatible with off the shelf components made from bamboo stalks.

PDS Summary
• Build frame and assemble components in 25 man hours or less
• Stay within a $155 budget for frame parts and materials
• Assure the bike can support riders of various sizes
• The bike must be aesthetically pleasing to the eye

Design Evaluation Bamboo
• Pros– Highly sustainable– Produces 35% more oxygen and absorbs 4x the CO2 than
hardwood trees– High Strength• ~30,000 psi in tension• ~14,000 psi in compression
• Cons– Heavier frame weight compared to its aluminum
counterpart– Mechanical properties vary between species

Carbon Fiber Webbing
• Pros:– High Strength– Low Weight– Wider strands allow quicker
wrapping time• Cons:– Not readily available in small
quantities– Expensive

Super Sap CLR Epoxy w/FAST Hardener
• Pros– Made from biobased renewable materials– UV Stability– High Tensile and Compression Strength
• Cons– 7 day recommended cure time– Can be hazardous if proper safety precautions are not met– 48 oz Kit - $47.95

Jig Assembly
• Pros– Upright position allows for
easier access to entire frame
• Cons– Wood support board is
less sturdy and requires holes to be drilled manually to attach jig components
