Assault AirBike Classic

Overview

The Assault AirBike Classic is the machine that put air bikes on the map in functional-fitness gyms, and it is still a reliable workhorse for interval conditioning at home. Resistance is generated by a 25-blade steel fan that pushes against the rider in direct proportion to effort, meaning beginners and athletes can train on the same bike without ever swapping a setting. The Classic uses a chain drive connecting the pedals to the fan, which delivers a familiar, slightly clattery feel that long-time riders associate with the bike, though it requires periodic lubrication and tensioning compared with newer belt designs. Twenty sealed cartridge bearings keep the motion consistent over years of hard use. The LCD computer displays speed, distance, calories, time, watts and heart rate, with several preset programs and a clear interval mode. The seat moves up, down, forward and back to dial in fit, and the multi-grip moving handlebars let you target the upper body or coast with your arms and drive only the legs. At under 100 pounds with built-in transport wheels it is reasonably easy to reposition. It is loud and not foldable, but for proven, affordable high-intensity cardio it remains a benchmark.
