Vehicle, Mobility and Transportation Design 3bee bicycle frame by Tamás Túri The essence of the concept of the 3bee urban bicycle frame is the production of a 3D printable sports equipment that due to its customization is appropriate for all users regardless of age, gender and physical abilities. The 3D printing technique enables everyone to implement the personalized, perfect, dream-bicycle. With this technique it is possible to easily and precisely harmonize the size of the frame with the other parts of the bike. The esthetic appearance of the bicycle can be tailored to the taste of its user by various colors and patterns.
