The Schwinn Airdyne AD3 is a long-discontinued, legacy entry in the Airdyne line, recognizable by its retro copper frame and no longer sold new – today it only turns up secondhand. Mechanically it’s built like its closer sibling, the Schwinn Airdyne AD4: a big metal spoked fan and two-chain, wedge-pin drive delivering Schwinn’s classic dual-action resistance, which scales automatically with effort and needs no dial or calibration. It doesn’t need to be plugged in, so it can go anywhere in a home gym. Where it differs from the AD4 is the console – an analog speedometer and battery-powered digital timer instead of an electronic display, with no built-in programs and a seat that’s cushioned but has no back support. Reviewers who bought one used consistently praise it as a simple, heavy-duty machine that still delivers a serious cardio workout decades on, while flagging the dated readout and the fact that, being out of production, it comes with no manufacturer warranty or parts support if something breaks.

What is a Air Bike?
What an air bike is
An air bike (or “fan bike”) uses a large front fan for resistance: the harder you pedal and push the moving handles, the more air the fan has to move, so resistance scales infinitely with effort. There are no settings to change — you simply work harder. Because arms and legs drive at once, air bikes deliver full-body, low-impact conditioning that is a staple of CrossFit and HYROX training.
Who it’s for
Anyone who wants brutal, joint-friendly cardio in a compact footprint — intervals, sprints, and calorie-target finishers. Belt-drive bikes run quieter and need less maintenance; chain-drive bikes cost less. Prefer a legs-only, cycling-style ride? A BikeErg is the closer fit.

The AD3 is a legacy, long-discontinued Airdyne — the same fan-resistance workhorse mechanics as the Schwinn AD4 (big spoked metal fan, two-chain drive, wedge-pin cranks) wrapped in an analog-console, no-frills package. Functionality is its standout: infinite, self-regulating air resistance that needs no calibration and no outlet. Its weakest dimension is versatility — a bare-bones battery-powered speedometer and timer, no programs, no backrest, and (since it’s out of production) no warranty or support if something breaks.
