There are quite a few heavy-duty air resistance exercise bikes that you can choose from at the moment. Among them, we can count the SOLE SB800, the Schwinn AirDyne AD7, the LifeCORE Assault Air Bike, and more. However, Samina has released its own model in 2019, this being the Stamina X 15-1175. This bike offers a very solid construction, includes a HIIT performance monitor, and definitely matches the standards and feature range of the other top air bikes.

Frame construction

The Stamina X air bike features a frame made of thick steel tubing combining ovalized and cylindrical bars in its construction for improved sturdiness and aesthetics. The only major ABS plastic element is the cover of the belt drive system. All the steel tubes in the frame construction are coated with a rust-resistant and abrasion-resistant paint finish. The color used is black; the only red parts are the bars that link the pedals to the handlebars and the flywheel. Also, the seat post features a chrome finish.

This Stamina exercise bike isn’t extremely large. It is approx. 53″ (135 cm) long, and 22.75″ (58 cm) wide, while the top of the handlebars reaches approx. 54″ (137 cm) above floor level. It is recommended, though, to allow at least two feet of clearance all around the unit for safe access and usage.

The fully assembled bike is fairly heavy. It weighs approx. 145 lbs (66 kg) which is at least three times the weight of the average road bike. This being said, its assembly may require two people. But on the other hand, all this weight provides superior stability.

Once the bike is assembled, its transport can be done with ease by only one person. Its front base features a set of transport wheels while the rear base is equipped with a lifting handle. Also, the rear base of the bike has two adjustable stabilizers which allow you to level your bike on any type of floor.

It’s important to mention here that even though the bike has a short bar that connects the seat tube with the oblique tube of the frame, this element should not be used as a step up support. That’s because it is covered by the plastic casing of the belt which may crack under extreme pressure.

Seat and handlebars

The Stamina X 15-1175 air bike includes a padded and contoured seat designed for extra comfort. It is also fairly wide offering plenty of contact surface. It is important to mention, though, that the slider of the seat features a triangular metallic plate to which the saddle attaches via three screws. This isn’t exactly a standard design, and if you will ever need to replace it, compatible options may not be too widely available.

The seat offers four-way adjustability (up, down, forward, backward). Its upright post has 10 adjustment positions, while its horizontal slider also offers several inches of front to back movement. This being said, the bike can accommodate users between 4’10” and 6’4″ (147 – 193 cm). It is also very durable, designed to support users up to 350 lbs (159 kg).

One of the notable features with regards to the bike’s seat is the horizontal adjustment system. The top slider of the seat is equipped with a small lever at the front, which can be easily unlocked in case you want to adjust the position of the seat while you are seated. Not all exercise bikes have this feature; in most cases, in order to adjust the seat, you have to dismount the bike.

Since it’s an air bike, the Stamina X 15-1175 features a set of moving handlebars. They have a multi-grip design so you can focus different upper body muscle groups during exercising. The handgrips don’t have pulse sensors. However, the bike’s performance monitor is telemetric.

Similar to other air bikes, the Stamina X model doesn’t have stationary handlebars. The performance monitor frame bar can serve as a fixed-grip, but this is not recommended, and the position is awkward anyway. The moving handlebars are directly attached to the pedals via two metallic bars. Therefore, they cannot become stationary; they continue to move for as long as you pedal. But on the other hand, the bike integrates foot resting pegs on each side which give you the possibility to only work with your arms.

Drive and resistance

The Stamina X 15-1175 is an air resistance only exercise bike. This means it doesn’t have an additional magnetic brake for resistance micro-adjustment. The main resistance-generating element is the large fan. Also, the bike doesn’t require an external power source.

Even though it doesn’t have a resistance adjustment system, this Stamina exercise bike delivers a dynamic response during exercising. Differently put, the faster you pedal, the more resistance you will get. This type of resistance is great for HIIT exercises and offers a quick and intense cardiovascular boost.

The bike’s drive system uses a standard (690-J6) poly-v belt. This type of drivetrain comes with several advantages. To begin with, a belt drive doesn’t need periodic lubrication. Also, the pedaling motion is very smooth.

The bike is equipped with a durable crankset. Each crank arm is reinforced by an outer plate to which the pedal attaches. The bike is rated for a weight capacity of 350 lbs (159 kg) which applies to the pedals and crank arms as well.

The included pedals are made of metallic alloy. They have standard threads, so in case you will ever need to replace them, compatible options are widely available. They don’t have SPD elements, but they do have toe cages with adjustable straps for improved foot stability.

Performance monitor

The bike is equipped with a performance monitor similar to the one included with the Sunny Tornado SF-B2729. It’s a unit designed for HIIT exercises. It features an LCD display divided into several windows in order to show multiple workout metrics at once, so you don’t have to use a scan function to rotate them. The display tracks time, total time, distance, watts, speed, RPM, calories, and pulse. You can select either miles or kilometers for the distance display. Also, for the pulse reading, you will have to wear a 5 kHz HR chest strap which is not included.

The monitor unit doesn’t have online connectivity, nor it is compatible with any fitness apps. However, it has several built-in workout programs. To begin with, it has three interval-based programs. These are 10/20 Interval, 20/10 Interval, and Custom. Needless to say, the 10/20 interval program requires 10 sec. of work and 20 of sec. rest, the 20/10 interval program calls for 20 sec. of work and 10 sec. of rest, while for the Custom interval you can set your own work and rest periods.

Target programs are also available. You can set up a workout target for time, distance, calories, and heart rate. If a workout target is selected for time, distance, and calories, the console will countdown from the selected value until you complete your set up goal.

The Heart Rate goal (or Target Heart Rate) is basically a different type of program. It has two preset values of 65% of your HRC, and 85% of your HRC. So, as the program starts, the monitor will beep if your pulse drops below 65% prompting you to increase your workout speed, while if it exceeds 85%, it will prompt you to reduce your workout intensity.

The console unit is very easy to use. Each Target program and interval program has its own button. The lower section of the unit features arrow buttons for increasing or decreasing values when selecting goals. The Enter button allows you to confirm a certain goal, while the Start and Stop buttons initiate or pause the programs.

The monitor unit is battery-powered. It requires two AA batteries which are not included. It has a Standby mode into which it will enter after 60 seconds of inactivity on the bike. To power it on, you can either begin pedaling or press one of the buttons.

Assembly and Maintenance

The main body of the bike with the seat, fan, cranks, and other drive elements comes pre-assembled. You only need to attach the two base tubes, the moving arms, the pedals, the monitor support bar, and the monitor. This shouldn’t take more than an hour. A set of tools for the assembly is included. Also, the manual provides very clear assembly instructions and schematics.

Once the bike is assembled, maintenance doesn’t require much. All you have to do is periodically check for loose or broken parts and re-tighten them or replace them before an accident can happen. Also, in case the fan accumulates dust, you can vacuum it from the outside without removing its metal casing.
