Bike is a British motorcycling magazine that was established and edited by journalist in 1971, originally as a one-off Car magazine special. Taking a leaf out of Car magazine's book, Bike published "Giant Tests", namely, head to head comparison tests, which were innovative at the time. Before then, motorcycle journals and magazines would test bikes only individually and in isolation from other bikes. The first "Giant Test", in summer 1971, was a comparison between a BSA Rocket 3 and a Norton Commando.
