Drive Train

 

Although this project was open to designing a bicycle entirely from procured materials, the initial decision was to purchase the complex drivetrain components such as gearing and braking systems. There were many reasons for this, including the complexity, tight tolerances and manufacturing requirements of these specific parts which could be considered a project in their own right. Furthermore, the securement of sponsorship from Bike Station meant that these normally expensive parts could potentially be acquired free of charge. The final reason for using parts from major bicycle manufacturers’ was the associated simplification in the manufacturing process due to the use of standardised components and fitting procedures.

 

The key additional challenges and drivetrain considerations include the management of cables at hinge mechanisms and ability to maintain chain tension during folding. Each of these design challenges has been considered in depth to relieve any potential issues during the manufacturing phase.
