Product Highlights
Patented Variable Fluid Twin Tank Resistance
The M550's side-mounted twin tank uses Dynamic's patented Variable Fluid innovation, allowing resistance to be adjusted instantly at the turn of a lever. The updated impeller design achieves 15% greater resistance than prior models, and the double-sealed, precision-aligned tank ensures tight tolerances and consistent performance over time.
Short-Frame, High-Access Design
At 1950mm in length, the M550 has a shorter frame than most commercial rowers, reducing floor space requirements without compromising stroke quality. The elevated seat height makes getting on and off the machine straightforward for users of all fitness levels and mobility ranges.
Bluetooth Auto-Adjust Monitor (BAM)
The Interactive Performance Monitor (IPM) displays time, speed, distance, stroke rate, calories per hour, watts, and 10-level resistance adjustment. Bluetooth connectivity and a built-in heart rate receiver compatible with major HR belts are included as standard.
Ergonomic Seat & Advanced Footboard
The contoured, textured seat rides on concealed Air Glide low-friction rollers for a silent, smooth action. Height-adjustable footplates with an Advanced Heel Cradle design and straps ensure secure, comfortable foot placement across a wide range of user sizes.
Deluxe Ergonomic Handle & Belt Drive
The ergonomic handle is shaped to minimize strain on forearms, wrists, and hands during extended sessions. A durable belt drive with an active recoil system provides consistent, reliable performance across high daily usage volumes.
Commercial-Grade Steel & Aluminum Frame
The M550 frame is constructed from high-grade steel and aluminum with a premium black finish and tough hardened dual anodized aluminum seat rails. Heavy-duty concealed transport wheels and rubber floor feet make repositioning easy while protecting floor surfaces.

Frequently Asked Questions
How does the M550 differ from the M350?
The M550 features a side-mounted twin tank rather than an angled front-mounted tank, resulting in a shorter overall frame length (1950mm vs. 2120mm) and a higher seat position. This makes the M550 particularly well-suited for commercial environments where ease of access and floor space efficiency are priorities.
Can resistance be adjusted during a workout?
Yes. The M550 uses Dynamic's patented Variable Fluid technology, which allows resistance to be changed instantly at the turn of a lever — without stopping or interrupting the rowing stroke. Ten resistance levels are available.
What type of resistance does the M550 use?
The M550 uses a side-mounted, double-sealed Twin Tank Adjustable Fluid Resistance system. The updated impeller design delivers 15% greater resistance than previous-generation models and provides a smooth, water-like rowing feel.
Does the M550 have Bluetooth connectivity?
Yes. The Bluetooth Auto-Adjust Monitor (BAM) supports Bluetooth connectivity and auto resistance detection. A heart rate receiver compatible with major HR chest belts is included as standard.
Can the M550 be stored vertically?
Yes. The M550 includes a vertical storage option with an upright footprint of approximately 860 mm × 810 mm, making it practical for studios and facilities with limited floor space.
What is the maximum user weight capacity?
The M550 supports users up to 150 kg (330 lb). Do not exceed this rated capacity.
What warranty is included with the M550?
The M550 includes a commercial warranty: 5 years on the frame, 2 years on the fluid tank, 2 years on mechanical and non-wearing components, and 1 year on wearing components.
Is the M550 suitable for users with limited mobility?
The M550's elevated seat height — comparable to an office chair — makes entry and exit easier than lower-profile rowers. It is used in personal training and rehabilitation settings, though we recommend consulting a healthcare professional before use if you have any physical limitations or medical conditions.
The Dynamic Fluid Rower M550 is a well-engineered commercial rowing machine that combines a compact frame, accessible seat height, and instant-adjustable fluid resistance into a durable package built for daily gym use.
