Team BIKES ( Bikeshare I ntended K eyless Encrypted S mart-locks) Junior Colloquia 11/20/14 Mentor: Dr. Robert Newcomb Librarian: Ms. Robin Dasler Members: Luke Boegner, Peter Cho, Kyle King, Nicholas Fleming, Tyler Gilman, Eric Huang, Joshua Lafond, Nathaniel Kruder, Tim McLaughlin, Isaac Noh, William Poh, Emily Ruppel, Libby Wei Conclusion
Bikeshares are a force for change Relatively new trend Promotes healthy lifestyles and sustainability Capital Bikeshare Washington, D.C. Hubway Bikeshare Boston, MA Conclusion
Problems Current bikeshares are not well suited to college campuses Docks are inconvenient for short commutes High cost of bicycles and docking equipment Empty Docks Capital Bikeshare Conclusion
Solution: a stationless bikeshare enabled by smartlocks Eliminates docking stations I wanna Simplified implementation process park here! Convenient for travelling needs in college campuses or here! Conclusion

Grants UMD Sustainability Fund Spring 14: Awarded $4,000.00 Fall 14: Reapplied VentureWell Grant focused Conclusion
Budget Breakdown Bicycles Spent $563.58 $893.54 $255.58 $357.00 Future Spending $1127.16 $725.00 $4000.00 $128.16 Total Spent $2069.70 Total Future Spending $5980.32 Total Budget $8050.02 Conclusion
Branding & Pricing Apply to UMD & other college campuses Red Bar Inspiration of Red Bar Logo Conclusion
Other College Bikeshares: Station-based Pricing Structure Seasonally/ Monthly/ Yearly/ Daily Numbers: Potential users, number of bikes Bikeshare at University of Michigan, Ann Arbor Conclusion
Focus Group (Spring 15) Process of getting IRB Gauge student current understanding of bikeshares Get feedback on web app and lock design(s) Conclusion
Conclusion Where we stand: Finishing the prototyping stages : 3D printed lock designs, testing existing locks : Operational code, meeting size constraints : Web app, Zigbee network : Filed for IRB approval, payment and branding scheme
Conclusion Long Term Objective: Complete the integration of the system parts to achieve: 2 bicycle system by mid-spring, 2015 5 bicycle system by Fall, 2015 Final objective: Demonstrate a proof-of-concept for a stationless bikeshare on a college campus
Conclusion Greatest Challenges: Changing focus while staying true to the project s original goals Mobilizing the team to effectively move forward Individual time management and coordination
Conclusion Recommendations: Organization - distribution of power Apply for grants Spend time together
