The Frame and Construction 

The Circuit Fitness AMZ-587R Magnetic Recumbent Bike

The AMZ-587R Magnetic Recumbent Bike features a heavy-duty wide steel tubing frame that is coated with anti-corrosion paint for longevity. Of course, it also integrates ABS-made covers for the drive system and console.  

Its robust base framework features front and rear steel stabilizers with rubber end caps. Thus, the bike has superlative stability that doesn’t give in to wobbling during vigorous workouts. 

Moreover, there are adjustable levelers at the rear base which enable users to balance the bike on a surface that is not even.  

The bike’s net weight is not specified but we presumed it should be around 90 lbs./41 kg since its gross weight is 99.2 lbs./45 kg, and this positively impacts the overall stability.  

To easily move the unit for storage, a lifting handle and transport wheels are attached to the rear and the front bases, respectively.  

The overall assembled dimensions are 55’’ long by 24.8’’ wide by 48.5’’ high. In other words, its required workout area perimeters should be 4’6’’ in length by 2’1’’ in width. An extra clearance of 1-2′ will be necessary around it for safety and easy access purposes.  

As aforementioned, its walk-through design enables every user to step in and out of the bike without struggling, regardless of their physical status.   

The Seat of the Circuit Fitness AMZ-587R Magnetic Recumbent Bike

The Circuit Fitness Recumbent Bike seat (with the backrest) is large, contoured, and adequately padded for extra comfort. As a result, users can work out longer with ease without putting stress on certain parts of the body.  

In other words, you will be able to workout relaxed and aggressively for the ultimate fitness goals. Its dimensions are 11’’ long by 17’’ wide.  

The seat is attached to a slanted rail and could be adjusted to several positions horizontally (backward and forward) while its elevation is also impacted. Hence, users between the heights of 4’10’’-6’5’’ can be accommodated.  

The adjustment can conveniently be done while seated via the lever on the right side of the seat, and the backrest does not adjust independently without the seat.

The Handlebars  

There are 2 sets of handlebars on the Circuit Fitness AMZ-587R Magnetic Recumbent Bike. One set is at the front while the other is on the seat.  

The short vertical handlebars at the front are without EKG sensors but are designed for an alternate workout position, while those attached to the seat have the contact sensors for heart rate reading.  

The 2 sets of handlebars are coated with soft rubber foam that ensures comfortable and secure grips. In other words, it prevents slippage and blisters that may occur as a result of frequent and prolonged workouts.  

Finally, none of the handlebars is adjustable, however, they are optimally positioned to be suitable for different users.  

The Pedals 

The Circuit Fitness AMZ-587R Magnetic Recumbent Bike has standard and simple pedals that are large, textured with adjustable safety straps. They are self-leveling and are made of durable nylon plastic with a metallic core.  

They are designed to accommodate different foot sizes and the use of standard gym shoes.  

The pedals provide maximum footing stability that won’t be compromised even during an intense workout.  

The Drive 

The recumbent bike is equipped with a belt drive system that comprises an anti-stretch Poly-V belt, pulleys, cranks, and a flywheel. Its operation is smooth and quiet, and also, it doesn’t require any periodic lubrication or adjustment as opposed to a chain drive system.  

So, you can utilize or exercise with the bike at any time you see fit and you don’t have the obligation of taking the drive’s shrouds apart for maintenance.  

You can watch a TV show or listen to music without interference from the bike’s operation. Also, people around you, including neighbors won’t be bothered by your workout activity.  

The flywheel’s weight is not specified, but it is usually between 8-12 lbs./3.6-5.4 kg. Either way, it still provides a smooth and consistent motion for a recumbent bike.  

You may pedal in reverse because the drive is bidirectional.  

The Resistance 

The unit has an eddy current magnetic resistance system that consists mainly of a servo motor, a magnetic brake pad, and a flywheel. These are the elements that are responsible for generating resistance.  

When powered by the included power adapter and the resistance is activated, the servo motor moves the magnetic brake pad close to the flywheel and emits magnetic fields that eventually cause a drag.  

The closer or farther away the magnetic brake pad is to the flywheel the harder or easier the resistance intensity becomes, respectively.  

This also means that no actual contact is made between the internal mechanisms of the resistance system. Thus, no friction occurs and no part is expected to wear out and be replaced.  

There are 24 resistance levels adjustable via the console and they provide easy to fairly difficult resistance intensities that are suitable for those that are recovering from an injury, beginners, intermediaries, and everyone else whose goals are to lose weight, improve heart and lungs’ health, and overall physical fitness.  

The Console

The console on the Circuit Fitness AMZ-587R Magnetic Recumbent Bike has some interesting features that put it on a mid-range category level. These include the integration of a backlit LCD monitor, 15 workout programs, Recovery Function, Body Fat, a sound system, USB charging port, MP3 3.5mm port, a tablet and water bottle holders.  

The LCD monitor tracks 7 workout metrics that include Time, Distance, Speed, Watts, RPM, Calories, and Pulse. It does so with high readability that can’t be diminished when viewed in a poorly-lit room. 

The 15 workout programs involve a Manual Mode, Beginner Mode (4 program selection), Advance Mode (4 program selection), Sporty Mode (4 program selection), Cardio (Target HR training mode), and WATT Program (WATT Constant Training Mode). 

The Manual Mode gives you the control to select the resistance level you wish to use for a workout and to also set workout goals for Time, Distance, Calories, and Heart Rate.  

The Beginner, Advance, and Sporty Modes have 4 preset workout programs each. When any of them is selected, a certain resistance level is automatically applied.  

The Cardio Mode automatically adjusts the resistance level based on your heart rate. It has 55%, 75%, and 90% HRC (Heart Rate Control) values that you can select from, while there is also a Custom HRC that allows you to set a preferred customized value.  

The Recovery Function calculates your fitness level and produces an output that is usually between F1 (excellent) to F6 (poor).  

While the Body Fat Function calculates your body fat percentage. It starts measurement upon prompting you to supply personal data such as Gender, Age, Height, and Weight.  

There are few navigation buttons on the console, and they are pretty easy to use. The owner’s manual has graphic guidelines on how to use them.   

Lastly, the console is not telemetry-enabled, and it doesn’t connect to any online app.  


As aforementioned, this unit has built-in speakers, a USB charging port, MP3 port, water bottle, and tablet holders; all are designated on the console. Except of course for the second water bottle holder that is on the drive system’s casing making it a total of 2.  

Therefore, you may choose to keep a water bottle up on the console or down on the drive’s casing for maintaining proper hydration. The sound system and the USB charging port allow you to entertain yourself by listening to good music while your device battery is always charged.  

The retractable tablet holder securely accommodates a tablet device. Also, the view of the display screen doesn’t get blocked when a device is placed on it.
