SF-RW5809 Frame Construction
The Sunny Hydro+ SF-RW5809 rowing machine features a steel frame combining rectangular and oval tubing in its construction. All the steel bars come coated with a corrosion-resistant gray paint finish. The front section of the structure has two large guards of thermoplastic material. The two footrests are also plastic-made.
The rower is not too large compared with some other models. With all the parts assembled, it is approximately 77.2″ (196 cm) long and 18.9″ (48 cm) wide, while the top of the fitness monitor reaches approximately 44″ (112 cm) above floor level.
It is also necessary to leave at least two feet of clearance at the rear of the machine and on each side for easy access and correct safe usage.
This Sunny Health & Fitness rower does not have a folding frame like the SF-RW5866 model. However, it can store vertically, resting on its front stabilizers. When held vertically, its footprint becomes 44″L x 18.9″W (112 x 48 cm), while its height reaches 77.2″ (196 cm).
The unit is not heavy, weighing 73.6 lbs (33.3 kg). Thus, one person can carry and assemble the rower. In addition, with water inside the tank, it weighs close to 100 lbs (45 kg). Once completed, transporting the machine is easy as its front base integrates a set of small wheels. Also, its rear stabilizer features adjustable levelers.
Seat and other parts
The Sunny Hydro+ SF-RW5809 rower has a large, contoured seat for optimal comfort. Its top is high-density foam to reduce the impact on your tailbone. It is also textured to prevent slippage.
The base frame of the seat is steel-made. It integrates three sets of wheels—two slides on top of the rail and the third under the rail for improved stability. The wheels come equipped with sealed ball bearings for smooth seat movement. They also have a silicone rubber layer on the outside for reduced noise.
The machine’s rail is not perfectly horizontal. It is about 0.5° inclined forward and has a maximum user weight capacity of up to 275 lbs (125 kg). Furthermore, it is relatively long, so this Sunny rower’s applicable inseam length is approximate—41″ (104 cm). Therefore, the rower comfortably accommodates users up to 6’6″ (198 cm) with no problem.
The unit’s seat is reasonably high above the floor, and its height is approximately 15.5″ (39 cm) when extended to the back. Therefore, it is a plus for users with disabilities as it facilitates easy entry and exit.
The rower comes equipped with a set of pivoting footrests. They are made of durable thermoplastic materials and have heel guards and adjustable straps for superior foot stability. In addition, they are large enough to accommodate athletic shoes of all sizes.
Last but not least, the rower pulling handle consists of a short straight bar. It does not have any sensors or resistance controls. However, it has thick PVC foam sleeves for an improved grip. It is attached to a heavy-duty nylon strap that’s highly resistant to abrasion. Furthermore, its drive system does not require lubrication.
SF-RW5809 Resistance system
The Sunny Hydro+ combines water and magnetic resistance. To begin with, the rower comes equipped with a durable polycarbonate water tank. Its exact capacity is not specified. However, by considering its size, it is approx. 3 – 3.5 gallons (11 – 13 liters).
The tank integrates a 16-blade impeller attached to the machine’s pulley system. Thus, the impeller spins inside the tank through the water when you pull the handle, generating resistance.
The tank does not have any mechanical adjustment elements for the water level. So, if you want to add or remove the water, you must use the provided pump. The tank has a maximum water level marked, which you should not exceed to avoid overflowing or internal part damage.
The magnetic resistance system is pretty similar to standard upright bikes. However, it offers 16 distinct levels. It consists of a small magnetic brake and a flywheel at the tank’s base. The brake connects to the tension knob on the front part of the rower. Thus, when you turn the knob, the brake moves closer or apart from the flywheel to increase or decrease the workout resistance.
Of course, since the primary resistance system of the machine uses water, the rower provides a dynamic response. Therefore, the hydro blade will spin more quickly inside the tank and provide more resistance if you stroke faster.
This effect is pretty close to rowing a real boat through water which is a plus, especially for users who are training for professional competitions.
The Sunny SF-RW5809 rower comes equipped with a mid-range fitness monitor. It features an LCD that tracks time, time/500 m, strokes, strokes per minute (SPM), total strokes, calories burned, distance, and Pulse.
The distance displays in meters only; there is no option for changing it to yards or miles. The pulse reading function requires a 5 kHz wireless HR chest strap (not included), as the machine does not have integrated contact pulse sensors. A pulse recovery function is also available.
The fitness monitor has two workout modes which are Manual and Race. The Manual mode offers two options. For the first one, you can row, and the monitor will record your completed strokes, strokes per minute, distance traveled, etc.
You can select time, distance, strokes, calories, and pulse goals for the second option. After choosing a goal for any of these metrics, the monitor will indicate the remaining value from your goal and notify you when you have completed your goal.
The Race mode has 15 levels of difficulty. For level 1 (L1), the Time/500m is set at 8:00, while level 15 (L15) is 1:00. Thus, if the Race mode is on, you will race with the computer for the set time/distance.
The center display will indicate the user and the PC on two separate lanes. Each virtual boat advances towards the set goal, and the race will end when either your boat or the PC boat reaches the goal.
The battery-powered fitness monitor requires two AA batteries. In addition, it begins counting your data when you start rowing and automatically turns off after four minutes of inactivity on the machine. In sleep (or idle) mode, the LCD indicates the current date (year, month, day), room temperature, and clock.
SF-RW5809 Assembly and Maintenance
The front section of the rower with the magnetic resistance elements comes pre-assembled. However, the other parts do require user assembly.
You must insert the seat onto the rail, connect the rail to the front frame section, connect the rear stabilizer, and attach the water tank, the footrests, and the fitness monitor. Therefore, it shouldn’t take more than an hour of your time. All the necessary tools come with the machine, and the manual provides precise assembly instructions.
For maintenance, it is advisable to keep the machine clean and periodically inspect it for loose or damaged parts to ensure it still functions properly. The water inside the tank requires chlorine purification every six months; a pack of chlorine pills comes with the machine. The internal parts do not require any lubrication.
