Schwinn AirDyne AD2 — model code 100425, discontinued reference review

A discontinued U.S. model listing, not a current buying recommendation

Schwinn’s U.S. AirDyne AD2 product page now labels the item discontinued and says it is not available from SchwinnFitness.com. The manufacturer’s older AD2 route bearing model code 100425 redirects to that U.S. page; its product record carries UPC 708447909084. A separate Schwinn parts-library record identifies code 100425 as the 2014 North American AD2 and links its owner manual. Together, those first-party records connect the observed U.S. listing to the North American model-code/manual path; 100425 is a manufacturer model code, not a retail SKU, and no individual used bike or serial number was inspected. Schwinn’s support article says the serial identifies a particular unit’s revision and directs owners to support for the matching manual. The AD2 is a past model, not a substitute for the current AD6: a used listing may be incomplete, incorrectly identified or in unknown condition. This page is an identification reference only and has no purchase link.

What the manufacturer page actually supports

The product description says the AD2 uses wind resistance for an upper- and lower-body workout. The page title and product imagery identify an AirDyne AD2, and the photo shown here is Schwinn’s image associated with the U.S. listing. The U.S. page does not provide a retail SKU or serial-specific details. Schwinn’s support article says a physical serial is needed to identify a particular AD2 unit’s revision and directs owners to support for the matching manual and parts information.

The manufacturer comparison row is keyed to model code 100425 and lists a 46 × 25 × 50-inch body, 96-pound product weight and 250-pound maximum user weight. The code-linked North American 2014 manual independently confirms the 250-pound maximum, 46 × 25 × 50-inch body diagram and two AA batteries; it gives an 82 × 61-inch minimum workout area but does not list machine weight. These are model-code and manual values, not measurements of an individual used bike.

Keep the weight record explicit rather than silently choosing between editions. Schwinn’s comparison row for code 100425 lists 96 pounds, while the separate International AD2 (2014) manual lists an 81.6-pound machine weight. The North American code-100425 manual does not give a weight, and the International manual is a distinct market edition; do not transfer its 81.6-pound figure to the U.S. model or treat either figure as a measurement of a specific unit. For an actual secondhand bike, the frame label and serial still matter.

Two manual entries mean check the exact revision

Schwinn’s manuals indexes include a general AD2 manual and a separate AD2 (2014) entry, alongside different regional records. The official U.S. model-code route now resolves the observed AD2 product path to code 100425, and the official parts library associates that code with “SCH AD2 Airdyne | 2014” and a North American English assembly/owner manual. This establishes the model-code path for the discontinued U.S. listing, but it does not identify the serial number of a particular secondhand bike. Before assembly, maintenance or repairs, compare the frame label and serial with Schwinn’s support guidance and ask support to confirm the correct manual and parts for that physical unit.

The North American code-100425 manual lists a 250 lb maximum user weight, a 46 × 25 × 50-inch body outline, two AA batteries and an 82 × 61-inch minimum workout area; it does not give machine weight. Keep this manual distinct from Schwinn’s separately indexed International “AD2 (2014)” manual, which lists 81.6 lb. The manufacturer comparison page’s 96 lb entry is tied to the U.S. code-100425 AD2 row, but neither number is an individual-unit measurement. These records answer what Schwinn documents for the model paths, not what condition, package or serial a used seller will deliver.

Schwinn describes the AD6 as the current model in the position the AD2 used to occupy. That wording signals a successor in the lineup, not guaranteed parts interchangeability or identical fit, controls, resistance response, dimensions or package contents. The AD6 product page lists SKU HCB0260-OS; the AD2 source listing has no SKU. Keep those product identities separate.

Questions to settle before considering a used AD2

• Does the seller show the frame label and serial number, and will Schwinn confirm the edition and matching owner/assembly instructions?
• Are the console, pedal straps, handles and any claimed accessories physically present? Compare the seller’s item with the instructions for that revision.
• Can Schwinn confirm availability of replacement parts for the exact serial number? The support article says parts may be limited and advises owners to ask support.
• What condition, delivery method, return terms and seller warranty apply to this particular used unit? Schwinn notes that third-party or secondhand condition and history cannot be verified by the manufacturer.

These are verification questions, not findings about any particular secondhand bike. No used unit was inspected here, and the current documentation does not support a dependable price or condition judgment.

Who this page helps

Use this assessment to identify the discontinued U.S. Schwinn AirDyne AD2 model-code 100425 listing or prepare questions about an older bike. It confirms the manufacturer code path and linked North American manual, while keeping the serial-specific identity and condition of any physical used unit open. It does not compare ride feel, publish a buying shortlist or certify personal capacity, space or training fit. For a new machine, research the exact current model separately; for an AD2 already in a home, compare the frame label and serial with Schwinn’s support guidance before operating or servicing it.
