The Frame and Construction

First of all, the Viatek Flex Bike Ultra is available in 4 different colors, which are black, purple, red, and blue. TheseViatek Flex Bike Ultra Review are variants of the same folding bike with the same set of features and quality except for the colors. Therefore, you will be able to choose your favorite color for the bike.

It is a compact and foldable bike that can easily fit in a small room or apartment and will be liked by those that want portable stationary exercise bike. The overall assembled dimensions are 42.5 inches long by 21.5 inches wide by 41 inches tall. This means a workout area of 3 feet 5 inches long by 1 foot 8 inches wide will be required.

But it is recommended to provide extra clearance of at least 2 feet on both sides and the rear for a safe and comfortable workout and the ceiling height of the room it is going to be used should be at least 6 feet high.

While on the other hand, the folded dimensions are 17 inches long by 21.5 inches wide by 54 inches tall and weigh just about 39 pounds/app. 18 kg. It is also equipped with transport wheels at the front base which is designed to aid in the relocation process. Therefore, simply fold and roll away to the storage destination without hassle.

The frame is made heavy-duty steel that is finished with anti-corrosion and scratch paint that should prevent rusts and scratch. However, this is an indoor bike meant to be used indoors otherwise, if exposed to rains and water this could damage the console and you don’t want that to happen. It is sturdy enough to support up to 300 pounds / 136 kg maximum user weight.

Stabilizer bars are integrated into the bike to ensure that stability is achieved; one at the front base while the other at the rear base.

The Viatek Flex Bike Ultra also provides full-body workouts, unlike the conventional stationary bikes that mostly provide lower body workouts. This is possible because of the upper body resistance bands that are located just below the main handlebars. You can utilize this feature when you wish to exercise the upper body and may choose not to do so as well, it is optional. The resistant bands’ handles are coated with rubber/foam material to provide a comfortable grip that will prevent blisters on the palms also.

The frame and the overall construction of this foldable semi-recumbent bike will not disappoint you in terms of quality, sturdiness, and stability.

The Seat and Handlebars

Just a reminder, the seat and the handlebars are basically among the elements that make a stationary bike comfortable and desirable if they are well designed.

Therefore, the Viatek Flex Bike Ultra has got a recommendable large seat with backrest that suggests providing much-needed comfort.  Both the seat and the backrest are well cushioned and padded with foam and covered with a vinyl material that offers nothing but comfort to the butt. You will be able to work out longer without feeling violated or bored which increases the possibility of you attaining your fitness goals quickly.

To further boost the comfort you get from the seat and the opportunity of exercising in different workout positions the seat has 3 recline adjustable levels, and could also be adjusted vertically, which is upward and downward.

Now, this also increases the number of different users it can accommodate regardless of their height, however, one user did complain of not been too comfortable for him because he is short but says he still enjoys the bike.

There are side handles or armbars to the seat which are coated with foam material for a comfortable grip as well. These are designed or meant for the sole purpose of providing support to you so that you could achieve more leverage to pedal harder while you enjoy the comfort.

It has multi-grip designed handlebars that also have the heart rate sensors embedded in them so that your heart rate data can be read and transmitted to the display/monitor each time you grip them during a workout.

The handlebars are also designed to provide a comfortable grip because they are covered with foam/rubber material.  However, you cannot adjust the handlebar because it is fixed but that does not reduce the comfort you will because the seat adjustability got you covered.

The Drive and Pedals

The Viatek Flex Bike Ultra features a belt drive system that is very popular due to its smooth and quiet operation. This means that the bike operates with a consistent, smooth, and quiet motion that will set your mind at ease because you do not only enjoy the workout but you do not also bother the family or the neighbors with unwarranted noise.

You can use this bike and workout anywhere you find it convenient to do so because of its compact and mobile design and of course quiet operation.

Not also forgetting that you have the liberty of entertaining yourself by watching your favorite TV show or listening to some good music.

The bike also features non-skid pedals which means they are slip-resistant with safety adjustable straps to further stabilize the security of your feet during a vigorous workout.

The Resistance System

The Viatek Flex Bike Ultra comes with a manual adjustable magnetic resistance system. The multiple resistance levels could challenge you enough to burn more calories.

You can easily adjust the resistance by turning the tension knob that is designated on the double frame just below the resistance band and the console. The resistance can be increased by twisting the tension knob clockwise and decrease by turning anti-clockwise.

However, the resistance band that is designed for upper body workout is not adjustable; nevertheless, you should be able to tone every muscle group in the body even as you lose weight and improve physical endurance.

The Viatek Flex Bike Ultra’s resistance system is maintenance-free because it is a magnetic resistance system.

The Console

The console is relatively large and larger than most consoles on other stationary bikes of the same category.  TheViatek Flex Bike Ultra Review problem is that the monitor is not backlit and therefore could be difficult to read the metric in a poorly lit room. The good news is that it has a large metric display with high readability if used in a well-lit room.

The console is basic with three control buttons; which are Reset, Mode, and Set.

It is very easy to manipulate or use the console and you will be able to track speed, time, distance, SCAN, calories, and heart rate. This is so important because you will be motivated and be focused on achieving your fitness goals. Being able to view your heart rate will also help you to maintain your target heart zone at all times.

There is on the console a tablet holder where you could place your phone or tablet while working out, but the problem is, you may not be able to manipulate the buttons on the console or even view the display.

The console is powered by 2 AA batteries which are included. The display comes on when there is activity on the bike and goes off when there is no activity for a couple of minutes. This is to save battery power and no electricity is needed.


The only accessory present on the Viatek Flex Bike Ultra is the tablet holder which we think is badly positioned because it will block your view of the workout data being displayed on the monitor should you decide to place a tablet on it.


What more can we say about the storage of the Viatek Flex Bike Ultra? It is very easy and convenient to move andViatek Flex Bike Ultra Review store it away because of its compact and foldable design and the transport wheels that are also integrated into it.

It doesn’t even take up much space when fully assembled much less when folded. Anyone can single-handedly move the bike to a storage destination because it is also a lightweight machine of 39 pounds / 17.7 kg.

Approval Rating

The approval rating is a prerequisite for determining how well a product is accepted by its users. This simply solves half of your purchasing decision problem…well, at least we listen to users’ feedback because these are folks that have walked down the road and you can learn from them instead of trying to find out for yourself.

That being said, the Viatek Flex Bike Ultra has a very good and impressive approval rating with the majority of the users’ feedback saying they will recommend it.
