M1 HiRise vs Ash Build
Build Material
Edge: Tie
The WaterRower M1 HiRise S4 BLE features a powder-coated aluminum frame, offering a commercial-grade, durable structure designed for demanding home gyms or studios. In contrast, the WaterRower Ash Rowing Machine is handcrafted from sustainably sourced ash wood with a natural finish. Both models are made in the USA, but the aluminum construction provides a different aesthetic and structural profile compared to the traditional wooden frame of the Ash model.
Weight
Edge: WaterRower M1 HiRise S4 BLE
Weight is a major differentiator between these two rowers. The M1 HiRise S4 BLE weighs 200 pounds, providing a substantial, stable base suitable for high-intensity training. The Ash Rowing Machine weighs only 63.9 pounds, making it significantly lighter. This weight difference affects stability during intense strokes and ease of movement, with the heavier aluminum model offering more inertia and the lighter wood model being easier to reposition.
Dimensions
Edge: WaterRower Ash Rowing Machine
Size matters for storage and footprint. The M1 HiRise S4 BLE measures 86 inches in length, 24 inches in width, and 27 inches in height. The Ash Rowing Machine is slightly shorter at 84 inches long, with a width of 21 inches and a height of 22 inches. The Ash model has a narrower profile, potentially fitting better in tighter spaces, while the M1 HiRise is wider and taller, offering a more traditional, expansive footprint.
Connectivity
Edge: WaterRower M1 HiRise S4 BLE
Both machines include the S4 monitor, but connectivity differs. The M1 HiRise S4 BLE explicitly supports Bluetooth and connects to WaterRower Connect for app integration, allowing for digital tracking and workout programming. The Ash Rowing Machine lists the S4 Monitor but does not specify Bluetooth capabilities in its key specs. If you require seamless data sync with training apps, the BLE version offers a clear advantage in modern connectivity.
Seat Height
Edge: Tie
The M1 HiRise S4 BLE is a high-rise model with a 9-inch seat height, providing a traditional low rowing position relative to the frame. The Ash Rowing Machine is available in Lo-Rise and Hi-Rise options, with the base model listed as Lo-Rise at 22 inches height. The M1 HiRise offers a specific elevated frame design, while the Ash model may offer a lower starting position depending on the variation you select.
