Design of electric bicycle frame

U završnom radu obrađena je tema konstruiranja i tehničke razrade izrade rama električnog bicikla. Cilj je napraviti što stabilniju konstrukciju bicikla modularnog dizajna, a istovremeno tehnološki jednostavnu za obradu, kako bi troškovi proizvodnje male serije bili što niži. Zbog smanjenja mase kompletne konstrukcije, za izradu okvira koristio bi se aluminij. Konstrukcija bicikla izvedena je na način da je većina dijelova izrađena iz lima, pošto je to jedan od najdostupnijih i najpovoljnih načina obrade metala. U radu je razrađen koncept pojedinih dijelova bicikla te su oni proračunati i dimenzionirani, uz predviđenu i proizvodnu cijenu istih. Tehnička dokumentacija izrađena je u programu SolidWorks.The final paper deals with the topic of design and technical development of electric bicycle frame. The aim is to make the construction of a modular design bicycle that is stable and at the same time technologically easy to produce, so the production costs of the small series are as low as possible. Due to the reduction of the mass of the complete structure, aluminum will be used as frame building material. The construction of the bicycle has been made in such a way that most of the parts are made of sheet metal, as this is one of the most convenient and accessable methods of metal processing. This paper elaborates the concept of individual bicycle parts and they are calculated and dimensioned, with the production price. The technical documentation was created in SolidWorks
