CEDARVILLE — Four seniors from Cedarville University are building and testing wooden bicycles for a capstone engineering project. Team leader Jake Miller said the project offers a unique opportunity for students to connect their interests in engineering, woodworking and cycling.
Assistant professor of mechanical and biomedical engineering Jay Kinsinger, the team’s capstone instructor, shares these interests. Kinsinger has been building wooden bikes for four years and riding across America and Europe. He has won top honors in the Dayton Carvers Guild show, Artistry in Wood, and built a folding tandem now displayed at the Bicycle Museum of America in New Bremen, Ohio.
According to Kinsinger, wooden bicycle frames are tough, lightweight and beautiful, with infinite design possibilities. Kinsinger said the bikes get attention because they look different, but he loves the smooth ride and the fun of building them.
The capstone team includes Miller, from Dillsburg, Penn., David Yoder of Plain City, Ohio, Gerrit Start of Saint Charles, Mo., and Cody Lewis, from Cambodia. Each student has taken the project in a different direction to investigate material strength, safety standards, efficient manufacturing and other concerns.
Kinsinger said the students must apply engineering tools in new ways to meet these challenges, and their results will eliminate guesswork from the building process. Each frame takes hundreds of hours to build, and weaknesses may easily remain hidden. The students have conducted extensive tests on materials to prevent this, and Miller said they will send completed frames to a bicycle test lab for further tests of strength.
Yoder said the team is also learning to stop and correct mistakes throughout the process to improve their results. “You have to be willing to do that,” Yoder said, “not be so arrogant to think what you do the first time is going to be the best you can do.”
Yoder said the project is sometimes frustrating because it stretches his abilities, but he enjoys learning through the process. “The work has been tremendous fun,” Yoder said.
Miller said he is using this experience to build a wooden triathlon bike outside class, and he hopes to race with it in the future.
