  1. Bicycle Energy Measurement System Exigo Technologies Denis Dmitriev Mimi Wu

  2. Overview • Introduction • Purpose • BEMS • Market • Timeline & Budget • Conclusion

  3. Introduction • Exigo Technologies • CEO & COO • Denis Dmitriev • CFO • Mimi Wu

  4. Purpose • Problem • Want to know how much calories you burned while riding your bike, but don’t want to be confined indoors? • Current Solutions • Expensive, complex systems • Our Solution • The Bicycle Energy Measurement System (BEMS)

  5. What is BEMS • BEMS is a simple, user friendly product that measures and computes the energy expended by the cyclist BEMS

  6. Features • User-friendly interface • Easy to enter personal information • Eg. Weight of cyclist & bike • Display • Velocity (km/h or mph) • Distance (km or miles) • Power (W or kCal/h) • Energy (kJ or kCal) • Trip duration • Average velocity/power

  7. How does it work? • Sensor package measures • Speed • Inclination • Display unit • Inputs personal info • Outputs energy expended

  8. Operation concept System Overview • Cyclist enters weight using the display unit • Start pedaling • Energy spent displayed on LCD screen

  9. Sensor package • Houses • main power supply • optical encoder • accelerometer • signal conditioning circuitry • Attaches to the fork of the bike

  10. Display unit • Mounts on the handlebars • Processes data from the sensor unit • Main point of communication with the user

  11. Market • Recreational Cyclists • Monitoring physical output is part of a healthy lifestyle • Fact: • 33 billion dollars are spent annually in the United States on weight-loss products and services

  12. Current products • Polar Electro, Power Tap & SRM • Cost • Expensive • Usability • Complex Installation • Calibration Required

  13. BEMS • Cost • Can be sold for under $100 • Usability • Easy to install • Snap on, Snap off • No previous experience required

  14. Milestone Hardware Design Finalized All components received Hardware Ready and Working Firmware provides desired level of functionality Demo Timeline comparison Proposed Actual Oct 05 Oct 05 Oct 14 Nov 15 Nov 07 Dec 18 Nov 20 Jan 11 Dec 10 Jan 13

  15. Budget comparison • Proposed Budget: • $300 • Actual Spending: • $140 • Funding: • $110

  16. Future development • Extensive Testing and Calibration of the BEMS • Further research and implementations of velocity measurement • Improvements of display options and user interface • User Manual

  17. Conclusion • Interesting Project • Basic functions of the system works • Could always use more time

  18. Questions & Comments?
