Analysis of Naturalistic Electric Bike Rider Behavior: Energy and Power Considerations By Noelani Fishman and Breanna Piercy Graduate Assistant: Kwaku Boakye Professors: Shashi Nambisan, Chris Cherry Center for Transportation Research University of Tennessee, Knoxville
Goals Determine how much energy is put into pedaling a standard e-bike Analyze naturalistic behavior Interpret data about Power expenditure user’s energy distributionElectric bicycle’s efficiency Encourage use of electric bikes 5- 2
Introduction An e-bike is a hybrid between human and electrical power that uses an electric motor to assist its rider 5- 3UT hosted an on-campus e-bike share program in 2012 Currently, research continues centered around e-bikes at UT
Bicycle/E-bike Share Programs are self-serving bike stations in cities First 30 minutes free Return to other stationMainly in Europe and AsiaTwo cities:DenverNew York City E-bike share programs rare in US Started on UT campus in TN Ended within a year San Francisco plans on creating a program 5- 4
Classifications and Parts of E-Bikes How electric bikes operate: Power-assisted Power-on-demandElectric Bike Classification:Pedal AssistThrottle on DemandSpeed PedelicMoped or Motorcycle Three main components of an electric bike: The Battery The Motor The Controller 5- 5
Anatomy of an E-bike We will add a picture of an e-bike right here, and then use graphics to explain its anatomy. We haven’t done this yet because we are going to use a picture we take ourselves. 5-6
5- 7 Advantages of E-bikes Disadvantages of E-bikesPromotes exerciseOn some e-bikes, can pedal to power motor Easier to pedal More energy efficient for uphill and against wind riding Greener form of transportation Requires greater use of ab muscles because of weight Smaller environmental footprint than regular bicycles Heavier than normal bikes Expensive Increased crash rates on bike trails Difficult to steerCumbersome due to weight and size Greater speeds lead to safety concerns Not as much exercise as a normal bike Government regulations are vague and restrict usage
Country Experiences and Legislation of E-bikes E-bike usage in the United States is limited due to legislation put in place by state governments Limits put on e-bikes include: Speed limitMust follow regular bicycle regulationsMust have pedalsWeight restrictions Motor wattage E-bikes have increased in popularity globally In 2012, 29.3 million e-bikes were sold globally E-bike popularity has boomed in China and the Netherlands 5- 8
The Process 5- 9
Data we don’t yet know Equation we use to figure out power used by each rider 5- 10
Data we don’t yet know This would be a chart to explain the differences between electricity-free riding and full electricity riding 5- 11
Data we don’t yet know Conclusion of data and the result we got 5- 12
