BikeDenver Executive Director Molly North will leave the city’s bike advocacy group on Friday, according to a statement from Mark Chapman, president of BikeDenver’s Board of Directors.

Piep van Heuven, who led BikeDenver from 2008 to 2013, will hold the reins until the board hires a permanent replacement in May.

“I’ve had an incredible ride as the executive director for the past two-and-a-half years,” North said in a statement. “We’ve come a long way in that time and I am very proud of the accomplishments of our tremendous staff. I am grateful to have had the extremely fulfilling and always challenging opportunity to advocate for people who bike in Denver.”

Under North, BikeDenver’s membership and staff doubled. She advocated for Denver’s first protected bike lane on 15th Street and the city’s first parking-protected bike lanes on Arapahoe and Lawrence. North sparked the conversation about a bikeable Broadway, which will undergo a major redesign sooner than later.

“She is leaving the organization positioned for continued success with wonderful momentum from new branding, a fresh website and an impressive year-end fundraising campaign,” Chapman said. “We thank her for her dedication to BikeDenver.”

Chapman said the decision was “a pretty new development” and was mutual. The board will hold a retreat this weekend to begin looking for a new director, which Chapman said could be a national search.
