The Sandwichbike gets its name from the fact that its frame is made from two weather-coated layered plywood plates, that most of the custom-made components are sandwiched between. A series of aluminum “smart cylinders” connect the two plates to one another, while also serving as mounting points for things like the seat tube, headset and bottom bracket. Buyers will receive everything (including the necessary assembly tools) by mail in a flat cardboard box, and put it all together themselves – there are less than 50 parts in the entire kit. The designers inform us that in the final production version, a complete bike should weigh around 13 kilograms (source: Gizmag).

Circular Design Strategies 

Sandwichbike components

  • Product Attachment and Trust: the Sandwichbike can be completely built by the consumer themself, which enables the build-up of an emotional bond and narrative with the product.
  • Product Standardization & Compatibility: the different parts come in a box and can be interchanged across different models. 
  • Product Dis- & Reassembly: all the parts and tools are included in the kit assemble (and reassemble) the bike yourself.

Business Model Archetypes


  • Classic long life model: the Sandwhichbike, a durable product that is both eco-friendly and an eye-catcher, can be bought online or by distributors.

Product Life Cycle stage

World Bicycle Production

  • Mature stage: the global market for bicycles grew rapidly till the 1990s and since then the market is quite stable, although in some parts of the world the bicyle market is still growing (source: WorldWatch)
