As part of an ongoing project studying the use of electric-assist bicycles, or e-bikes, a research team led by TREC's John MacArthur conducted an online survey of e-bike users on their purchase and use decisions. The results, highlighted in this infographic, suggest that e-bikes enable people to bike more often, bike farther and carry more cargo than on a traditional bicycle. In addition, e-bikes let people ride a bike who otherwise could not because of physical limitations or distance.

Bicycle and pedestrian safety has emerged as a top priority for U.S. Transportation Secretary Anthony Foxx and the Department of Transportation. With this in mind, the department’s top research official visited Portland State University, home to the U.S. DOT-designated national center for livable communities.
Greg Winfree, the assistant secretary for research and technology, visited Portland State’s transportation research and education center June 13. Center Director Jennifer Dill and researcher Christopher Monsere gave Winfree a tour of the center’s living laboratory: Portland’s active transportation infrastructure.
Winfree, an advocate for improving safety for vulnerable road users, explored the city’s various bicycle safety efforts, including bike boulevards, protected bike lanes, bike boxes, bike-specific signals and signage. He also learned of pedestrian research involving traffic signals, crossings and modeling.
The tour highlighted research projects funded through U.S. DOT’...Read more
The NITC program's executive committee has selected a new roster of projects for funding under the National Institute for Transportation and Communities, or NITC, program. The committee chose 10 projects, totaling $900,000, under the NITC theme of safe, healthy and sustainable transportation to foster livable communities.
The projects are national in scope and reflect priority areas including transit supply and outcomes, and pedestrian and bicyclist behavior.
Projects selected include:
- A bicycle and pedestrian miles traveled project for Washington state.
- A study that measures the effectiveness on social media on advancing public transit.
- A look into crowdsourcing the collection of data on transportation behavior.
- A national study of Bus Rapid Transit outcomes.
A complete list of projects and principal investigators is below:
- National Study of BRT Development Outcomes: Arthur Nelson and Joanna Ganning, University of Utah
- Crowdsourcing the Collection of Transportation Behavior Data: Christopher Bone, Ken Kato and Marc Schlossberg,...
OTREC at Portland State University welcomed Eva Heinen of the University of Groningen, The Netherlands, for a special seminar June 18. Around 40 people attended the presentation, held at the Intelligent Transportation Systems Laboratory and titled “Cycling in the Netherlands and Multi-Modality.”
Eva Heinen is assistant professor of infrastructure planning and mobility at the Department of Spatial Planning and Environment, Faculty of Spatial Sciences, University of Groningen. She earned a Ph.D. from Delft University of Technology in 2011 focusing on bicycle commuting.
Many people in Groningen and The Netherlands as a whole combine transit and bicycling for trips. A typical configuration involves cycling from home to a train station and then renting another bicycle to reach the final destination, Heinen said.
Few people take bicycles on transit, Heinen said, and buses don’t offer bike racks or other accommodations. Folding bikes, whose compact size allows for portability, are one exception, Heinen said. Electric-assist bikes are also popular, particularly with older people.
Heinen has published many papers on cycling in international and national journals and has a large international network in cycling. She spent three months at the University of California in Davis as a visiting scholar. She is a member of the editorial board of Rooilijn, a Dutch journal for science and policy in spatial planning; a member of the Bicycle Committee; co-chair of the...Read more
Even as Portland racks up bike-friendly honors, ongoing research at Portland State University is shedding light on a new travel option that promises to get even more people on two wheels. Electric-assist bikes, or e-bikes, could hold the key to increasing cycling, particularly among women, older adults and people with physical limitations.
Portland State researchers Jennifer Dill and John MacArthur are exploring people’s perceptions and attitudes toward e-bikes and evaluating their use to see if these bikes encourage new cyclists. This spring, they’re loaning out locally made, GPS-equipped e-bikes to 120 people to learn about people’s actual experience using the bikes, marking the first time such research has been done in the country.
The research also includes a survey on e-bike use, which will help others understand the potential market. People who have ridden e-bikes can participate in this research by taking the survey at tinyurl.com/e-bike-survey.
E-bike use is increasing in North America, with many people switching from private cars and others using e-bikes to keep cycling as they age or after an injury. Increased use brings increased scrutiny, and efforts are already underway to limit where e-bikes can go and who can ride them. Many states require e-bike riders be licensed, set age limits or both.
Some local regulations prohibit e-bikes on bicycle and pedestrian paths. The city of Toronto,...Read more
