JKANGFIT H640 Rowing Machine Review 

The JKANGFIT H640 Rowing Machine is a foldable, full-body low impact cardio rower that is designed for home use. It supports 300 lbs./136 kg maximum user weight capacity as opposed to the Merach Q1 Magnetic Rowing Machine that supports up to 350 lbs./158.7 kg.  

The slide rail length is 48.6’’ long, thus, users that are up to 6’3’’ tall or with an inseam of 37.5’’ can work out without experiencing restricted full leg extension.  

It was released in 2022 and it is suitable for beginners and intermediary fitness level users wanting to improve overall physical well-being.

The Frame & Construction 

JKANGFIT H640 Rowing Machine

The JKANGFIT H640 Rowing Machine is sturdily constructed to support a higher maximum user weight capacity. Its frame is steel that is coated with anti-rust black paint, while the drive system’s shrouds, the pedals, the console casing, and the stabilizer bars’ end caps are made of ABS.  

The front and rear stabilizers with adjustable levelers are robust for optimized stability. Therefore, the unit can be stable on different types of floors, these include tiled, wooden, or carpeted surfaces.  

There are transport wheels at the front base of the rowing machine which easily facilitates the relocation process. After all, the unit only weighs 61 lbs./27.6 kg.  

The overall assembled dimensions are 72.44’’ long by 22.83’’ wide by 33.85’’ high. Consequently, the workout area required would be 6’ (184 cm) in length by 1’9’’ (58 cm) in width, and extra clearance of at least 2’ on each side and the rear part of the machine for ease of access and safety purposes.  

The seat-to-floor height is 13.4’’, while the folded dimensions are 29.13’’ long by 22.83’’ wide by 53.54’’ high. Hence, a storage area with measurements of 2’4’’ (74 cm) in length by 1’9’’ (58 cm) in width can conveniently accommodate it.  

The Seat of the JKANGFIT H640 Rowing Machine 

The seat of the JKANGFIT H640 Rowing Machine Review

The seat on this rower is the same as the one on the Sunny SF-RW520008 Rower. It is contoured, textured, large, and padded to provide maximum comfort. It has 2 big rollers that run on top of the rail, and one underneath for smooth, stable, and quiet back-and-forth motion.  

Due to its deep contoured design users won’t experience slipping off it while exercising. 

Although, some users purchase a cushion/gel seat cover to improve the overall feel for a prolonged rowing activity.  

The Handlebar 

The handlebar is straight and cylindrical, and it is coated with anti-slip soft rubber foam material for secure and comfortable grips.  

It has a strong nylon strap that is connected to the drive system attached to it.  

There are no heart rate sensors on the handlebar, nor any control button.  

The Footrests 

The footrests are large enough to accommodate most foot sizes or gym shoes. They are also ribbed with adjustable safety straps and heel guards that would guarantee stable and secure foot placement.  

They also pivot so that your feet adhere to their movement during a workout. This indeed reduces, if not eliminates ankle stress. 

The Resistance  

The resistance control knob of the JKANGFIT H640 Rowing Machine

This is a magnetic rowing machine. In other words, it has elements such as magnetic brakes, and a 7 lbs./3.17 kg perimeter weighted flywheel integrated to generate resistance.  

The resistance system is frictionless because the magnetic brake pads emit magnetic fields around the flywheel without contact to cause a drag that would ultimately produce resistance. The closer the magnetic brake pads are to the flywheel the more intense the resistance becomes and the farther away it is to the flywheel the less intense the resistance becomes.  

There are 16 adjustable resistance levels; they represent easy to difficult workout challenges. Most users, especially beginners and intermediaries would appreciate the workout challenges they provide.  

To increase or decrease the resistance level, you will have to manually turn the tension knob that is right below the handlebar clockwise or counterclockwise, respectively. 

No power is needed to get the resistance to work. No maintenance is required because no part wears out in the long run. Also, the operation of the rowing machine is almost whisper-silent and smooth.  

The Console 

The console of the JKANGFIT H640 Rowing Machine

The console features an LCD monitor that tracks Time, Distance SPM, Counts, Strokes, and Calories Burned simultaneously via the segmented windows.  

The readability is good. However, if viewed in an environment that is not well lit it will be compromised because the monitor is not backlit.  

The Distance metric unit is measured by meters and cannot be toggled to a different measuring unit. 

Moreover, the console is not Bluetooth enabled, nor compatible with any workout app.  

There are 4 easy-to-use navigation buttons: Mode, UP/DOWN, and Reset.  

The monitor is powered by 2 AAA batteries that are insertable at the back of the console. The display comes alive once rowing activity begins or when the Mode button is pressed, and it automatically turns off if the unit stays idle for a few minutes.  

Accessory 

There is a built-in tablet holder on the console. This is integrated to help users keep a smartphone/tablet device handy for taking calls, and watching workouts, or entertainment videos while exercising on the unit.  

Although, any device that is placed on the holder will block the view of the monitor.  

Storage 

The JKANGFIT H640 Rowing Machine is lightweight, foldable, and transportable. These make it to be easily stored away.  

It weighs 61 lbs./27.6 kg and its folded dimensions are 29.13’’ long by 22.83’’ wide by 53.54’’ high. So, a storage area with measurements of 2’4’’ (74 cm) in length by 1’9’’ (58 cm) will suffice.  

Finally, the front-mounted transport wheels enable an easy relocation process by one person.
