Bike Shelf Design ProjectBy: August Kim, Enting Liu, Kim Harmon, Valentine Asalu
AbstractThe primary objective of this design project is to design a bicycle shelf that can be attached to the rear of a bicycle and also be folded up to create a place to store goods. It must also be able to fold out and display the goods that were stored inside. The product is being designed to be very cheap yet durable so traveling merchants can afford and use it for a long period of time. We also decided that the product should be sold in a certain market. An area where there the population of street merchants/vendors is great would be an ideal area to sell the product to. Finally, with this information, our team has the necessary information to produce the most consumer appealing bike shelf.
