Team TRAMS design evidence for a low-cost bicycle intended for city roads and light off-road use, documented through geometry selection, material justification, static CAE checks and manufacturing-cost reporting.

Can a student team define a manufacturable bicycle frame for mixed city and light off-road use while keeping stress, deflection, ergonomics and cost inside competition constraints?
The design reports combine SolidWorks geometry, ANSYS Workbench stress checks, component selection, manufacturability discussion and a cost breakdown. Loads were applied at the head tube, seat post and bottom bracket to evaluate frame response.
The frame study reported maximum stress below the material ultimate tensile strength and a high static safety factor, with maximum deflection around a quarter millimetre in the documented loading case.
This is competition-level undergraduate evidence, not validated product engineering. It is useful because it shows early design ownership, report discipline and mechanical reasoning before the later KTH energy and Siemens thesis work.
The bicycle was framed as a practical, low-cost design for city roads with some off-road capability. The reports document material screening, frame geometry, wheel and drivetrain choices, brake selection and manufacturing assumptions.
AISI 4130 chromoly was selected as a practical compromise: lower cost than carbon fibre or titanium, higher strength than common aluminium options, and suitable weldability for a competition manufacturing route.
This page is not meant to compete with the later Siemens thesis. It is supporting evidence: early leadership in a technical team, ability to turn a design idea into a documented engineering package, and comfort with CAE-style reasoning before specialising in heat and power technology.
