Carlton Reid has departed BikeBiz, 22 years after founding the brand in 1996.
He will now work as a transport correspondent for Forbes.com.
The industry veteran will continue to contribute expert guest posts via the BikeBiz website on an ad-hoc basis.
"BikeBiz has been my life for 22 years, and I'm sad to be leaving the post of editor-at-large," said Reid. "The magazine and website are in the capable hands of James and Rebecca, and I will keep in touch with the industry through their fine reporting.
He added: "It's been an immense privilege to work for so long on one title reporting on an industry that I love. The bike market is facing challenging times but, as I know from my three decades reporting on the industry, it has faced such challenges before, and cycling always bounces back."
Last month, Reid was awarded Transport Journalist of the Year in Press Gazette's British Journalism Awards for Specialist Media.
He took his first steps in the world of cycling journalism in 1987 when, during his first year at university, he became the deputy editor of Peter Lumley's Bicycle Times magazine. BicycleBusiness was founded nine years later, before being sold to Intent Media in 2006, becoming BikeBiz in the process.
Reid remained editor for a time before handing over the reins to Jonathan Harker in 2008. He stayed on as editor-at-large, contributing breaking news stories on a regular basis.
NewBay Media, which purchased Intent in 2012, was acquired by Future Publishing earlier this year.
BikeBiz editor James Groves said: "I'd like to personally thank Carlton for his tireless efforts throughout my tenure, and for the innumerable contributions in the decades prior.
"I am delighted he will continue to provide BikeBiz readers with expert insights from all corners of the cycling industry."
