Answering the call for a StepMill that can fit into more spaces and reach more users, we are excited to introduce the much anticipated StairMaster 4G. As the newest addition to the StairMaster family, the 4G delivers the same heart-pounding StepMill workout with a great calorie burn through a low-impact stair climb. Designed to fit perfectly into hospitality, boutique, and multi housing training centers, the 4G has harnessed the quality members have experienced over the past 4 years with the 10G and the recently launched 8Gx. With a footprint of 54" x 29" and a height clearance of only 8 feet, the 4G is the solution this market has been missing.

Available with a variety of OpenHub console options, safety-stop sensor and a redesigned handrail system that supports multiple climbing positions and includes integrated speed and stop controls for a better user experience. Additionally, the service panel removes with 4 fasteners, allowing for easy access to drive train and electronics.

• VERTICAL AND RESIDENTIAL WARRANTY
• 7 INCH STEP HEIGHT
• 8FT CEILINGS
• 29 INCHES WIDE (FITS INTO ANY DOORWAY)
• AVAILABLE TO SHIP AUGUST/SEPTEMBER

The Nuts and Bolts - A quick explanation as to why our drivesystem works: The 10G, 8Gx and 4G all share the same mechanical design, championed by a generator based drivesystem vs Alternator. As a user climbs stairs, the generator creates resistance; this resistance prevents the steps from 'free-falling' - this is why the creation of resistance is important. Because the generator-based drivesystem is lightly geared (has a low gear ratio), the generator does not have to spin at a high rate to generate resistance. This is important because it means lighter-weight users won't have an issue generating resistance. In contrast, previous designs (pre-2019) utilized an alternator which requires a high gear ratio (needs to spin fast in order to generate resistance), higher gear ratios mean more friction in the system and thus needs more downward force to move. More friction is also prone to other issues.
