Critical Mass

Join XR as we reclaim the public roads of Boston by bicycle. We will bring a few XR flags, and some flyers to hand out. We'll be joining up with Boston Critical Mass and taking part in a long standing celebration of transportation alternatives.

Start gathering at around 5:30pm - ride starts at 6:00pm

About Critical Mass:

Critical Mass is a vision of a happy, bike-friendly world replacing our polluted, congested roads, a protest for better cycling facilities and against car culture, a mobile paean to bicycling’s joys, a merry ride downtown and through the neighborhoods with friends, and more – all rolled into one convenient monthly ride right after work!

Critical Mass is a party on two wheels to celebrate bicycling – a fast, friendly, clean, efficient, healthy, cheap, sensible, and fun way to get around the city.

Critical Mass is not an organization. It is a coincidence. It is a xerocracy. Make your own flyers! Make a route map--maybe it will be followed! Bring a sign, noisemaker, or cupcakes to the ride!

We ride on the last Friday of every month at 5:30 PM in Copley Square.

This month, join thousands in over 200 cities worldwide, and hundreds in Bostonalone, in celebrating Critical Mass.
