"We're definitely at some kind of a tipping point," said David Watson, executive director of MassBike (massbike.org), a nonprofit cycling advocacy and education group.
Data on commuter bicycle use are scant, Watson said. On his daily ride from Arlington into Boston, he sees "more and more bike traffic from week to week." He mentioned a survey showing a 70 percent increase in ridership between 2002 and 2006 in Cambridge, quoted on the website of the League of American Bicyclists (bikeleague.org). He also said there is a spike in demand this year for MassBike's introductory on-site Bicycle Commuter workshops for local companies (three in 2007 compared with 15 and counting in 2008).
Of course, bike commuting has room to grow: The 2000 Census estimated that fewer than 0.4 percent of all journeys to work were made by bike.
