Guy Kesteven is one of the world's most experienced bike testers. Having started out working in bike shops, Guy moved into journalism in 1996 and has since written for some of the most respected bike publications out there, including BikeRadar, Cyclingnews and Bike Perfect, while also running his own YouTube channel GuyKesTV. Yorkshire-born Guy is a mountain biker through-and-through, and after more than 25 years as a bike tester, knows what separates the wheat from the chaff. Still, Guy is more than comfortable on drop handlebars, too, not least with the rise of gravel riding. Guy is 180cm tall.
