  1. Improving Tricycle Biomechanics: Concept Tricycle Biomechanics Team March 22, 2007 Xin He, Katherine Wong, Mario Bollini, Elizabeth Au, Lindsay Todman

  2. Community Partnership • Abdullah: tricycles versus wheelchairs • Medical, environmental, stigmatic reasons • Rory: synchronous versus asynchronous crank • Power efficiency, mobility • General difficulty in communication

  3. Concept: Modify Current System • Provides tangible results for community partners by the end of the term. • Will seek to optimize: • Gear ratio • Crank configuration (synchronous vs. asynchronous) • Crank position • Steering system

  4. Modules • Steering • Gears • Ratio, derailers, speed, arms • Crank • Symmetric and Asymmetric • Adjustability • Position

  5. Next Step:Testing power output • Find the maximum power output for different people using the hand crank • This power output should be measured for a reasonable period of time to ensure it is sustainable • Vary the position of the crank and see how the power output changes
