Improve the urban cyclist's commute with intermodal transportation.
I targeted opportunities to make additions to the train interior early in the design process. Concepted storage systems included dedicated train carriages, foldable/automated bike racks, and under seat bike locks. Systems either maximized the train's capacity to hold bikes, or eased the commuter's experience with storage and security aboard the train.
After examining various train interior solutions, I turned my attention towards designing a compact bicycle to address the issue of minimizing size, space, and weight. The last bike sketch shows the rear wheel of a bicycle folding into its frame, an idea that would eventually develop into JACK.
During the build, JACK took on the properties of a jackknife, or switchblade, hence the name, JACK. The rear wheel folds into the bike frame the same way a switchblade folds into its handle. A liner lock, highlighted below, could then be adapted and applied to secure JACK in its expanded and collapsed positions.
Before machining the final prototype, the design was worked out in detail with SolidWorks. The orthographic views show JACK reducing in length without increasing in width, a benefit of the jackknife design unlike other folding bicycles on the market.

Although the prototype articulates the expansion and contraction of JACK, renderings complete the design with a collapsible carbon fiber seat, detailed pedals and gears, handlebars, and a clean color scheme. The liner lock has also been illustrated as a initial step to proof of concept.
JACK presents a great amount of room for development. The liner locks could work in theory to secure the bike in it's expanded position, but an automated mechanism to expand and collapse the bike in a swift motion has yet to be explored. The concept as a whole provides an original foray into the design of folding bicycles and transformative products.
