Ditch the car, put that CharlieCard away and pump some air in your tires.

That’s because Friday, May 20 is Bike to Work Day.

It’s a celebration right in the middle of National Bike Month and Bay State Bike Week that calls on everyone who can to commute to work in the bike lane.

“We think it’s important to celebrate everyone who rides in Boston, and we want to make it easier for new riders to start commuting,” Boston Bikes, the city-sponsored cycling initiative, said in a statement.

The city planned to host a big early-morning get-together at City Hall Plaza from 7:00 a.m. to 9 a.m. with some music and a free breakfast.

The riders had been encouraged to join one of a dozen “convoys” from around Greater Boston, then converge at City Hall.

“The City of Boston is pleased to be celebrating National Bike Month and Bay State Bike Week with the tens of thousands of people in the greater Boston area who bicycle as a mode of transportation, for exercise, or just for fun,” said Chris Osgood, City of Boston Chief of Streets. “Boston offers miles of off-road bike paths and on-street bike lanes, over a hundred Hubway bikeshare stations, and other amenities to help people ride bikes to their destinations, near and far, safely and conveniently.”

There are lots of other bike-hyping events to attend throughout Bike Month. For example in Somerville, bikers on Sunday, May 22 plan to take a historic tour retracing the path Paul Revere trotted down on his horse that fateful night.

Still too nervous to ride a bike through the busy, tangled mess that is Boston’s roads?

The city offers an “Into to Street Riding Clinic” periodically through October. The next one is Saturday, June 4 at the Boston Water and Sewer Commission in Roxbury from 12 p.m. – 2 p.m.
