  • DON’T DELAY: We’re placing another order for #BicycleColorado masks made by our friends at @primalwear TOMORROW (5/14) at noon! Click the link in our bio to get yours now!
We’re thrilled to see so many people out enjoying (and often rediscovering the joy of) riding a bike right now, and we’re asking ALL bicyclists to do their part to prevent the spread of #covid19 by wearing a mask or other face covering when out for a ride. Doing so keeps you, your loved ones, those around you, and all Coloradans safer while helping reduce stress on our medical system. If you still need a mask, click the link in our bio to pre-order one now and support our advocacy work! Thanks so much to everyone who has already purchased, and to @primalwear for supporting our efforts over the years. Ride on.
  • #BicycleColorado volunteers and staff members spent time today helping @denverurbangardens and @denverfoodrescue deliver “Grow a Garden” food boxes to home-bound families in Denver—via bike! Supporting our community on two wheels makes for a great way to spend a sunny day. Many thanks to our friends @ddchen47, David M., and @juggernautcargo for your help! Head to or to learn more about these great local organizations. #rideyourbike
  • Tonight the #BicycleColorado team celebrated Stacey, our outgoing Development Director, with a virtual happy hour. Stacey has been an absolute rockstar for BC. We’re sad to see her leave, but thrilled for her as she heads out on a new adventure (hopefully in the #BikeAdvocacy space!) in North Carolina. Please join us in wishing her well!
