Modular Urban Bikepack is the end product of a group design project I’ve participated.With other 4 group members, we followed the process of which a design project would work at small design studio.After market research and interviews, we decided our target group: urban bikers. Understanding urban bikers’ demand with their bike bags, we set out to design a modular bike bag which can be detached from the bicycle and become part of one’s backpack. Such feature offers the convenience for users to carry their bike bag and belongings with them after parking their bikes. The project began with drafting and brainstorming, followed up with prototype testing during which we determined the actual size and design of the bikepack.Then came the stage at which we made the actual bikepack and tested if the mechanism works well, that is, if the it can be fitly installed to a bicycle. And nally we did a product shoot for our nal design proposal.
