Portland's love affair with e-scooters has only just begun.

That’s the big takeaway from a report released Tuesday by the Portland Bureau of Transportation (PBOT), which detailed last year’s four-month e-scooter trial. The report concludes that e-scooters were popular enough with Portlanders to be invited back for a one-year pilot.

During last year's trail period, people could pick up an e-scooter—provided by companies Bird, Lime, and Skip—anywhere in Portland's city limits for a quick, relatively affordable ride, and drop the pay-per-minute scooter off on a sidewalk whenever they're finished using it.

Between July 23 and Nov 30 of 2018, people took 700,369 trips on e-scooters in Portland, spanning 801,887 miles, according to PBOT’s report. The average trip length was 1.15 miles, while rides in East Portland averaged 1.6 miles. Thirty-four percent of Portland riders reported using e-scooters instead of a taxi, Uber, or Lyft, and two-thirds of people using e-scooters said they used them specifically for transportation, not just to go on a joy ride.

Perhaps the most important finding: Portlanders, and especially younger Portlanders, are crazy about e-scooters. While 62 percent of all those surveyed expressed a positive view of them, that number shot up to 71 percent for those under 35 years old.

The report found that, unsurprisingly, there was an increase of scooter-related injuries during the pilot period—and that a full 90 percent of riders did not wear helmets—but “most injuries seen by emergency rooms across Multnomah County were not severe enough to warrant emergency transport.”

While 74 percent people of color polled by PBOT said they felt positive about e-scooters, there was also some anxiety around the prohibitive cost and risk of being racially profiled.

“It is not in our culture to pick up something off the street, ride it, and leave it for the next person,” one person of color told PBOT in a focus group.

Despite these concerns, there was significant e-scooter use in the more racially diverse, lower income pockets of East Portland. PBOT required each participating company to deploy at least 100 e-scooters to East Portland each day, and the results imply this strategy paid off: 44,155 occurred there in the original pilot period.

People with disabilities, meanwhile, said they recognized that e-scooters hold some potential for transportation; but improperly parked e-scooters caused serious accessibility barriers. At least one person with a disability said that people riding e-scooters on public sidewalks made getting around more difficult for them.

In its report, PBOT indicated plans to continue analyzing e-scooters, and addressing issues and concerns, throughout the upcoming year-long pilot. While the report was fairly comprehensive in scope, it made no mention of e-scooters allegedly being thrown in the Willamette River.
