  1. Successes and Challenges of Electric 2- and 3-Wheelers in Developing Economies Christopher Cherry Civil and Environmental Engineering University of Tennessee, Knoxville TRB 2011 Emerging Technologies Subcommittee January 24, 2011

  2. Beijing repeals ban on e-bikes, Guangzhou bans all motorized two-wheelers China passes law granting right to bike lanes Weight/Speed Enforcement Threatens First viable e-bike ventures launched Sales surge after SARS outbreak Gasoline two-wheelers banned in many cities

  3. Emission Rates China

  4. Emission Rates Significantly Biases Public Health Estimates-Consider Exposure

  5. E-bike fatality rate more than 10x lower than car

  6. Battery production loss rates hover around 20-30% of the battery weight… Multiplied by millions of batteries a year

  7. Why so few outside China—is there potential? Cutting-Edge Tech Upgraded Tech Current Tech

  8. Back to the US: Can e-bike technologies be combined with bike sharing?

  9. E-bike Share Proof of Concept on UT Campus • Small Scale Project to Test Technology and Market • How to recharge batteries? • Can we exchange batteries? • How are vehicles secured? • How much energy is used-f(speed, weight, terrain)? • Can we tie in solar power (truly zero emission)? • What are environmental impacts? • Is there a positive public health impact? • How will students/faculty/staff use or pay? • What is the preference relationship with bicycles?

  10. E-bike Share Proof of Concept on UT Campus • Scope: • 15-20 bikes (sensored) • 10-15 e-bikes • 5 bicycles • 2 stations (unattended) • auto-locking rental kiosks • removable battery vending • scan card/credit card checkout • Serving • on-campus housing/ag campus • staff and faculty day trips • Launching in the next month!
