The IE Critical Mass is a fun bike ride that takes place every third Friday of the month. We meet at 7pm, ride at 7:30pm for you stragglers, in the REI parking lot located on the northwest corner of Foothill Blvd and Day Creek Blvd in Rancho Cucamonga.

Let's see if we can grow this thing and inspire people that bikes are a great way to get around. All experience and fitness levels are welcomed. No riders left behind!

Meet people who ride bikes for fun, sport, exercise, commuting. Invite your friends. Bring anyone who hasn't ridden a bike since they were kids. Join citizens of the Inland Empire who want to explore the region by bike.
