If you'd like to design bikes for a living, you can go to ID school, and adapt the assignments accordingly. But if you'd like dedicated instruction, there's actually a Tokyo College of Cycle Design. The only school in Asia dedicated to bicycle design, they offer two-, three- and four-year design programs.

There are four pillars to the program:

BICYCLE BUILDING

In this curriculum, students will acquire skills to build frames (including components) with the appropriate use of various tools. During their first year, students will take a common program designed for both courses. After learning about basic frame structure and how to handle jigs, students will create their own original frames. During the second and subsequent years, students will take up the challenge of creating of more complex structures, such as piste bike, BMX, and MTB.

BICYCLE MAINTENANCE

This program allows students to learn about bicycle assembly and maintenance, starting with the basics. They learn techniques for handling various types of bicycles and gain an understanding of the components and master ergonomics required for measurements through experience. This program also prepares students to obtain a bicycle engineer's license and a bicycle safety mechanic's license.

BICYCLE DESIGN

In this curriculum, students study a wide range of design skills related to bicycles. They gain an understanding of industrial design methods while using their hands, and classes include sketch training using illustrators and three-dimensional modeling of carbon wheels using CAD.

BICYCLE CREATION

This program is for third-year students in the three- and four-year programs. It is filled with projects to allow the students to demonstrate their creativity in a broad manner to the industry and to society. Students will create bicycles for specific targets or purposes, and will work on practical projects, including collaborating with companies and submitting their works to outside exhibitions.

As you can see, students are encouraged to experiment:

While the school does offer a scholarship program for international students and visa assistance, course instruction is in Japanese.
