Sammanfattning: An integrated bicycle lock has been developed in this thesis to counteract the increasing number of bicycle thefts that occur in Sweden. By integrating a robust user-friendly lock into the bicycle frame, the use of bicycle locks can increase, and the risk of theft thus decreases. The study begins with a literature search that runs throughout the work, where facts and solution proposals have contributed to the final design solution. The methodology has consisted of qualitative interviews leading to customer needs which then laid the foundation for a product requirements specification. From there, Pugh’s Matrix was used which resulted in a combined concept where a foldable lock was integrated in the upper frame tube of the bicycle frame. FEA calculations and material choices have been fundamental to the final design solution. The final product was a design solution that meets the most important customer needs as well as the standard SS-EN 15496: 2008 for bicycle locks and the standard SS-EN ISO 4210–6:2015 for bicycle frames with a combined weight of 1100 grams added to the frame of the bike.
