The objective of the collapsible bicycle design team is to design and construct a collapsible bicycle. This collapsible bike must fit into a volume of 6x 16 x 18 (the size of a large brief case). This bicycle must also support a load of 250 pounds, have few to no loose parts, ride like a normal bike, and have a functioning braking system. Using AutoGad, a 3-D model was constructed allowing the team to visualize the ultimate goal and areas for improvement. A flat plate style frame, made of three eighth of an inch thick aluminum, has been chosen along with a belt drive system. Calculations have been performed to ensure stability and support during normal operation. The gear ratio for this bike is 4: 1 and the mass of the frame is approximately 8.6 lbs. Construction of our design is currently underway.
