A new type of triathlon racing bicycle is presented by Allied Bioengineering. The final product is a fully adjustable bicycle capable of pre-race adjustments to allow for increased comfort and efficiency as well as decreased frontal area. The main adjustable parts are the diamond frame, seat angle and handle bar configuration. The design consists of daughter tubes within mother tubes allowing for elongation or contraction as necessary, which also results in angle changes. These changes are to allow the rider to change the bicycle to fit their dimensions and meet the required dimensions of the race as well as to allow changes for the type of race, whether short track, long track, straight or winding. The design was simulated and tested in NX 4.0 showing points of high stress and strain as well elemental stress.

Created in fulfillment of the course requirements for ENGG*3100 Engineering and Design III. This course combines the knowledge gained in the advanced engineering and basic science courses with the design skills taught in ENGG*1100 and ENGG*2100 in solving open-ended problems. These problems are related to the student's major. Additional design tools are presented, including model simulation, sensitivity analysis, linear programming, knowledge-based systems and computer programming. Complementing these tools are discussions on writing and public speaking techniques, codes, safety issues, environmental assessment and professional management. These topics are taught with the consideration of available resources and cost.
