2. Schedule 3. Originality eBike Comparison Contributions to Field 4. Evaluation Evaluation Methodology Expected Outcomes 1. Purpose Problem Importance 2. Approach Modules/Parts Technology and Testing

3. Purpose General Information Purpose  The Problem and Importance 2 Problem: Assisted biking dramatically expands the market, but current eBike systems are unintelligent, ugly, and cumbersome. Importance: The research areas required are motor design, electrical engineering, mechanical engineering, and industrial design. It is intended that the work be published in a way that makes is a useful reference for the process of building an electromechanical system.

4. Approachfeatures Approach Features 3 ABS braking Data logging and workout plans Fully wireless control Gearless drivetrain Integrated energy storage and charger in wheel Ratiometric torque control mode Water-resistant

5. Module Breakdownmodules Approach Module Breakdown  Modules 4 Two main modules

6. Module Breakdown modules Approach Module Breakdown  Modules 5 Outer Casing Motor Electronics and Batteries

7. Module Breakdown modules Approach Module Breakdown  Modules 6 Enclosure (19) Electronics and Batteries (16, 17) Gear and Mount (15)

8. Technologyonboard intelligence Approach  Technology  Onboard Intelligence 7 Intelligent velocity matching toque assist can provide either adjustable 1x - 2x torque or full torque Data-logging enables users to retrieve vital statistics such as calories burned or distance traveled Safety countermeasures provide back-up circuitry in the event of hardware failure

9. Testingmethodology Approach  Testing  Methodology 8 Mechanical and Electronic devices can be tested to determine specifications and areas of improvement User experience is determined by mass interaction with the device in order to determine flaws The look and feel of the device (subjective artistic impression) gauged by polling, art history, etc.

10. Originalityelectric bikes Originality Competitive Analysis  E-bikes 9

11. Competitive Analysisadvantages Originality Competitive Analysis  GreenWheel Advantages 10 GreenWheel is the least expensive kit when paired with a < $200 bicycle Most powerful motor Competitive cycle life and charge time Most advanced features (ABS/data-logging/workout plan potential)

12. Contributions Originality  Contributions to the Field 11 As much about the innovations required to make the device as the process through which the innovations are made Goal is to have a guide, or design reference, that can be used by others to design anything from a better toaster to a world ending robot

13. Evaluationmethodology Evaluation  Methodology 12 In-field faculty and local expert consultations to determine the extent to which the goals of the work have been met Physical evaluation similar to testing

14. Evaluationexpected outcomes Evaluation  Expected Outcomes 13 Strong Engineering Successful Industrial Design Useful Resource to Others
