MERACH R21 Self-Powered Magnetic Rowing Machine – 60 kg resistance, solid wood, wireless


Train anywhere without limits. The Merach R21 is a revolutionary rowing machine with a self-powered system that eliminates the need for an external power source. With cutting-edge magnetic resistance of up to 60 kg—twice that of standard home models—it delivers a professional-grade gym workout right in your living room.



Technological innovations:



  • Self-Powered System: Forget about cumbersome cables. The rowing machine generates its own electricity while you row. Plus, it supports 15W reverse charging via USB-C, so you can charge your phone or tablet while you work out.

  • Extreme Magnetic Resistance (up to 60 kg): A wide range of 16 resistance levels covers everything from light cardio to extremely demanding strength training focused on the back, shoulders, and chest.

  • Smart controls: You can adjust the resistance directly using the buttons on the handlebars or let the machine automatically adjust it based on the program you select in the app.

  • Ultra-quiet operation: With noise levels below 40 dB, the rowing machine is quieter than a hushed conversation. You can work out at night or early in the morning without disturbing the rest of the family.

  • Luxurious solid wood construction: The frame made of FSC-certified wood and the extended 125 cm double rails ensure stability and ample space even for users up to 195 cm tall.






Display and ergonomics:



  • Extra-large HD LED display: The four-panel screen is 120% larger and twice as bright as on standard models. Thanks to the adjustable angle (120°–180°), you’ll see your data clearly regardless of your height.

  • Comfortable seating: The reinforced ergonomic seat is designed for long workouts without discomfort.

  • Greater range of motion: The extra-long stride length provides 20% more legroom, which taller users will particularly appreciate.
