Veloelectric: Creating A Device That Harvests Energy From Bicycles, Austin Hall, Daniel Stohr, Tj Fox
Mechanical Engineering
Long distance mountain bikers, bike-packers, and many bikers in developing countries rely on electrical devices for safety and communication. These specific groups of people operate in areas with little to no electricity, and often times have no power to sustain their devices. The purpose of this Cal Poly senior project, VeloElectric, was to design, build, and test a kinetic energy harvester for bicycles that can be used to charge common mobile devices via USB. This senior project team created a device that attaches directly to a bicycle and uses vibrations to generate energy, which in turn powers a variety of …

The Smooth Shifters is a team composed of Alex Powers, Brandon Roy Sadiarin, George Rodriguez, and Torey Kruisheer. We are four senior mechanical engineering students at California Polytechnic State University (Cal Poly) in San Luis Obispo, California that are working on a senior design project for Specialized Bicycle Components, Inc. located in Morgan Hill, California. We will be under the advisement of Professor Sarah T. Harding of the mechanical engineering department at Cal Poly.
Specialized, one of today’s leading bicycle companies, is in need of a test setup that measures brake and shifter cable drag. High performance cyclists using time …

Mechanical Engineering
It was our mission to design and build a bicycle attachment that provides a safe, comfortable, and entertaining ride that can attach to any common bicycle for Rebekah, a 12 year old girl living with cerebral palsy. The aluminum frame bicycle trailer we built motivates Rebekah to exercise with a speaker that plays music when she pedals and ceases the music when she stops pedaling. The speaker and sensor system is controlled by an Adafruit Trinket microcontroller using the Arduino IDE. The trailer does not have a chain drive so Rebekah's pedaling will not actually contribute to the movement of …

Mechanical Engineering
California Polytechnic State University has been invited to compete in the Parker Hannifin Chainless Challenge Competition in 2014-15. Cal Poly has chosen a team of mechanical engineering students to take part. We have named our team “Bike Under Pressure” and all references as such refer to the team.
The challenge is to build a bicycle which does not have a solid mechanical connection between the power input of the rider to the power output of the wheel(s). After conducting research into different previous designs and brainstorming designs of their own, Bike Under Pressure developed two conceptual designs. One design featured …
