How delivery works
Your item’s shipping method and price are confirmed in the shipping calculator and at checkout. Here is what each delivery path means.
Driveway freight delivery
Your equipment is palletized and protected. The freight carrier schedules delivery, then uses a liftgate to lower it to your curb or driveway. Moving it inside and unpacking it are up to you.
Inside delivery & assembly
When selected and available for your address, the delivery team brings the equipment into the room, assembles and tests it, then removes the packaging.
Full truckload
For commercial builds and multi-pallet orders, a dedicated trailer keeps the full order together in one delivery. We confirm the unloading plan before the truck ships.
Size: 51" × 29" × 58" tall
Doorways: 29" at its narrowest, so it clears a standard 32" door
What Remanufactured Means
Every remanufactured machine is fully disassembled, deep cleaned, repaired or re-parted to factory spec, then tested under load before it ships. Backed by one year parts and labor, with extended coverage available.
Warranty Coverage
New and remanufactured equipment are both covered for one year, parts and labor, backed by us. Extended protection is available on either through BAG Care+. Used equipment is sold as-is with no warranty coverage, and is described honestly before you buy. We service nationwide - every ZIP code in the country - so coverage travels with the machine.
30-Day Returns & Exchanges
Change your mind within 30 days of delivery and you can return the machine or exchange it for a different size, color or configuration.
Return shipping is the customer's responsibility and a 15% restocking fee applies to preference returns and exchanges. Freight items must go back packaged to the same standard they arrived in. We will tell you exactly what that means before anything is collected.
Anything that arrives damaged or fails under warranty is handled separately and carries no restocking fee. Full terms are in our Returns, Exchange & Refund Policy.

I was thinking about getting Ozempic, but I’m not in the mood to go blind yet. So I decided I’d do it the old fashioned way and called CTX.

CTX stands by their products. I recently purchased a Precor elliptical from them & it arrived with a mechanical flaw. They coordinated with a technician to get my product fixed like new. They accomplished this despite the fact that my home was two states away. Special thank you to Nichole for staying accessible and attentive throughout the process!

Absolutely best in business! Not only is Dillon just genuinely a great human being, he’s real and honest. Loved everything I’ve gotten from him and the team. I’m about 10-15 pieces in deep with him and not stopping anytime soon! Absolutely recommend hitting these guys up for home/commercial equipment. New or refurbished!

Dillion was great to work with!! Super friendly, quick turn around time, and great at communicating! The guys who delivered it Robb and JJ were also amazing. They came prepared and were very fast and efficient. They offered to help us move around other equipment to ensure we loved our gym! Super nice people and an amazing company! I would highly recommend working with them. Oh and the equipment itself is high quality and looks great in our home gym!

Rebuilt in our Jarrell, TX shop
What remanufactured means here
Every machine we sell as remanufactured goes through the same process, whatever the brand or the price. Not a wipe-down and a price tag.
-
Inspected and stripped down
Assessed frame to console, then taken apart and checked part by part. Nothing gets judged from the outside.
-
Moving parts rebuilt or replaced
Every moving and touched component, from belts and cables to bearings, bushings and grips, is evaluated and rebuilt or replaced, then the machine gets a full cosmetic restoration.
-
Refinished and rebuilt to spec
Electronics bench-tested, frames and welds checked, panels refinished, then reassembled to the manufacturer's specification.
-
Tested under load
A full operational cycle under load before it ships. Anything that fails the final check goes back through service, not onto a truck.
Get an email when new machines land
Good units go fast. We'll email you when new machines land - nothing else.

Commercial-grade equipment, inspected and supported by warranty.
The StairMaster HIIT Air Bike delivers fan-based wind resistance that scales automatically with output - and is tested to withstand 1,400 lb of force, a structural rating that signals serious commercial construction beyond standard air bike specs. Dual-action moving handlebars engage the upper body alongside the pedaling motion for a complete full-body conditioning session, and the self-regulating fan resistance means every interval is exactly as hard as the athlete decides to make it.
A redesigned pedal system makes HIIT exercise transitions faster and easier, and shorter handlebars with a repositioned console improve display access during hard efforts. The HIIT console includes Bluetooth and ANT+ connectivity with programmable time, distance, calorie, time interval, and calorie interval modes. Adjustable seat accommodates users from 4'11" to 6'8". 146 lb, 51" × 29" footprint. Remanufactured.

Key features
Tested to 1,400 lb - Commercial Construction
Structurally tested to 1,400 lb of force - a durability rating that exceeds standard air bike specifications and signals the frame integrity needed for sustained maximum-effort commercial use in high-traffic HIIT and conditioning environments.
Fan-Based Wind Resistance - Self-Regulating
Fan resistance scales automatically with pedaling and arm effort - harder output equals more resistance, instantly and without adjustment. No preset levels, no ceiling, every interval is as hard as the athlete chooses to make it.
HIIT Console - Bluetooth & ANT+ · Programmable Intervals
The backlit HIIT console includes Bluetooth and ANT+ connectivity with programmable time, distance, calorie, time interval, and calorie interval programs - structured interval training built into the display without manual tracking.
Redesigned Pedal System · Improved Console Access
A redesigned pedal system makes HIIT exercise transitions faster and easier mid-workout. Shorter handlebars and a repositioned console improve display readability and access during hard efforts without breaking the riding position.
