E-bikes are the fastest-growing segment of the bicycle industry. They're popular with commuters and baby boomers who might not otherwise be able to get out on a bicycle.
The bikes, which can cost $2,000 or more, combine the frame of a regular bike with lightweight batteries and electric motors for extra zip.
Their sales jumped 72% to $144 million in the U.S. last year, helping to breathe life into bicycle sales that have been relatively flat, according to the NPD Group, which tracks retail bike sales nationwide.
Their popularity has led to conflict.
In bike-friendly southern California, as local land managers take cues from agencies like the National Park Service, some are banning e-bikes from bicycle paths. That has angered riders, said Morgan Lommele, of PeopleForBikes, a bicycle advocacy group and trade association.
Should E-bikes be treated like bicycles or motorcycles when it comes to roads, bike paths, and access?
