The RUNOW 6204B is one of the rowing machines released in 2021. In terms of features, it is pretty similar to the RUNOW 6203B that we’ve already covered here. However, it has a black color finish and it is slightly heavier.

Frame construction

The RUNOW 6204B rower features a frame made of walnut wood with a black paint finish. Like most other wooden frame rowers, it has a dual-rail design which is quite a plus as it provides extra stability for the seat and superior structural sturdiness. The machine also integrates several plastic parts. For example, the side covers of the rails, the adjustable sections of the footrests, and several other small parts are made from durable thermoplastic material.

Similar to the WaterRower Club model, this particular rowing machine is fairly large. It is approx. 82″ (208 cm) long, and 22″ (56 cm) wide. It is also recommended to allow at least two feet of clearance on each side of the rail assembly, and at the rear of the machine, for easy access and to be able to execute the rowing motion correctly.

The unit’s rail assembly is pretty long and the applicable inseam length for this machine is approx. 40″ (101 cm). Thus, it should be able to accommodate users up to 6’5″ (196 cm) with no problem allowing a complete leg extension. The rail-seat assembly is also pretty durable. The machine is rated for a maximum user weight limit of 350 lbs (159 kg).

This rowing machine is also pretty heavy. The package weight is approx. 108 lbs (49.5 kg), so its transport may require two people. However, once it is assembled, it can easily be moved by only one person. Its front base has a set of wheels for this particular purpose.

The rower rests on several rubberized levelers. Its frame is not foldable as is the case for the HouseFit Skyline model. However, the unit can be stored vertically. When in vertical position, the water can remain in the tank.

Seat and other parts

The RUNOW 6204B rower is equipped with a seat designed for optimal comfort. Its top is contoured in order to provide superior stability for the user. It’s made of a layer of high-density foam material so it’s not completely hard. However, it is a pretty firm seat. Also, its height is approx. 12″ (30 cm).

The base of the seat combines wood and steel elements. The side panels are made from the same wood as the frame with the black finish. The wheel rods and the other hardware are steel-made. The wheels are eight in number. Four of them slide on top of the rails, the other four on the inner sides of the rails. The wheels have internal ball bearings and a thick rubber layer on the outside for reduced noise and for a smooth seat movement.

The rower is equipped with a set of adjustable footrests. The adjustable sections are made from a tough and flexible ABS polymer. Although they’re adjustable, they are also large so they should accommodate athletic shoes of any size. They also have straps and heel guards for superior foot stability.

The wooden board to which the footrests are attached is set at an angle of approx. 45°. It is pretty firm so it provides great support for each leg push phase. Its angle is non-adjustable.

The machine’s pulling handle is a simple, straight bar. It has rubber foam grip covers for improved contact. It’s attached to the machine’s resistance system via a heavy-duty, braided nylon strap, highly resistant to stretching and abrasion. It does not have any controls or pulse sensors.

Resistance system

The RUNOW 6204B rowing machine is equipped with a slightly larger water tank than other rowing machines. It has a capacity of 20 liters (while most others only have a 17 l capacity). This being said, a little extra water in the tank can provide more resistance. However, the tank is not meant to be filled up to the top. It actually has a marking on the side with a maximum fill level.

The water tank is made of durable polycarbonate material. It features blue, transparent walls. It’s a simple, single-chamber tank, without any water level adjustment mechanism like the First Degree Fitness Apollo, for example. It also does not have any magnetic resistance adjustment elements.

Although the tank does not have any resistance adjustment system, you can still adjust the overall resistance provided by the rower. This can be done by manually adding or removing water. A siphon pump for this task is included.

The main resistance-generating element is a multi-blade flywheel that’s integrated into the tank and attached to the machine’s pulley system. Thus, when you pull the handle, the flywheel spins in the water generating resistance. The machine provides a dynamic resistance response. In other words, the resistance depends on how much strength you put behind each stroke, or how fast you stroke. The faster you stroke, the faster the flywheel will spin, and the more resistance you will get. This simulates the rowing of a real boat through the water.

Like most other water resistance rowers, the 6204B is not a very loud fitness machine. Of course, the spinning of the flywheel inside the tank water can be heard, but the noise level is pretty low. Also, most users have described it as pleasant rather than annoying.

Fitness monitor

The RUNOW 6204B rower is equipped with a pretty basic fitness monitor. It does not have pre-set programs, workout target functions, or online connectivity. It features an LCD display that tracks time, distance, calories, stroke count, and total strokes. It does not show split time and does not have a pulse reading function. So, in case you’ll want to monitor your pulse during workouts, you will have to use a different device.

The monitor unit is very easy to use. It has only one button. By pressing the button repeatedly, you can select the workout metric that you want to view. There is also a Scan Mode that automatically rotates all the metrics showing each one for a few seconds.

The monitor also has a Reset feature. You can press and hold it for a few seconds to clear all the values on it to zero, except for the total strokes.

The monitor unit integrates a device holder. It features a small shelf on its lower base that can act as support for your phone or tablet. The monitor is battery-powered. It requires two AA batteries which are not included. It starts counting your workout data when you begin rowing. It turns out automatically after four minutes of inactivity on the machine to save battery. It wakes up if you press the button or if you begin rowing.

Assembly and Maintenance

The front section of the machine with the water tank and the other drive and resistance elements comes pre-assembled. You only need to connect the two rails, the seat, and the rear small board. This shouldn’t take more than 30 minutes of your time. All the necessary tools are included and the manual provides clear assembly instructions.

For maintenance, it is recommended to keep the machine clean, especially the rails, to prevent any scratches or damage to the rail covers. The water inside the tank should either be changed periodically, or purified with rower chlorine tablets. Other than this, it is also recommended to periodically inspect the machine and check for loose bolts and parts.
