Rochester aims to become a more bike-friendly city by addressing 'last-mile' transit issues. This project focuses on modifying existing bike racks to increase their carrying capacity while maintaining space efficiency. The telescoping design allows the rack to fold against the bus when not in use, expanding downward and unlocked by the user for easy access. It accommodates a minimum of four bikes and is built with durability in mind. With a total budget of $700, the project combines structural engineering and usability studies to enhance community health and reduce congestion and pollution.

Prepared and Presented by Morgan DeLuca Telescoping Bike Rack for a Public Bus
Project Overview • Rochester is pushing to become a more bike friendly city • There are issues arising with ‘last-mile’ transit • Benefits include reduce congestion, lower cost, increase in public health and less pollution
Project Description • Goal: Modify current bike rack to increase carrying capacity of bicycles
To reduce space when not in use, it will fold up, against the bus • When needed, it will be folded down by the user
After folding down, it can be unlocked by the user and extended in order to have more room for storing bikes • After a bike is removed, it can be contracted to reduce the length
Major Specifications Length of Rack when fully extended = 40-52 in Minimum Number of Bikes = 4 Minimum Carry Weight (static) = 415 lb Time to unload/load bike for first time user = 30-60s
MSD Team • 2 ME and 2 ISE would make up the team. • ME Responsibilities • Structural Analysis, CAD model, fatigue and vibration analysis • ISE Responsibilities • Ergonomics, usability and human interface, Optimization of loading/unloading process to minimize time
Budget • A total budget of $700 was given • Tubing makes up a majority of the cost, approximately $500. Welded, 304SS of various diameters were used to make this estimate. • Other items needed would be a bracket assembly to attach the rack to the bus, welding materials, and the bicycling securing method
