Comparison Kettler Rivo 2 vs Kettler Rivo M

The maximum horizontal distance between the pedals of the cross trainer, determines, respectively, the length of the athlete's step when working on the machine. It is believed that for people of average height, a step length of 400 – 500 mm is optimal, and many cross trainers are made with this calculation. At the same time, there are models with a variable step length, which allows you to adjust it to the personal preferences of different users.

Anyway, the step length should be chosen depending on height, physique and personal preferences. Too small a step will lead to the fact that you have to mince, and the imitation of walking will turn into marking time, and too wide will lead to inconvenience and an unjustified increase in load without increasing efficiency. Ideally, it is advisable to test the cross trainer before buying — how comfortable you will be on it. This applies to both fixed and adjustable step lengths.

— Handlebar controls. The control buttons for training modes are placed on the handles of the cross trainer. With their help, you can change the load without stopping the workout. However, the control options in each model may be different.

— Fan. The cross trainer has a fan. This feature is useful for cooling during intense workouts, especially in warm weather.

— Bottle holder. The presence in the design of the cross trainer k of a special stand on which you can put a bottle or glass. Thus, you will always have a supply of water at hand, and to replenish its amount in the body you will not have to be distracted from working out on the machine.

— Colour display. The presence of a colour display in the design of the machine. This element does not affect the main features of the device. However, such displays are considered more convenient and pleasant to view than black and white. Some models may include various additional features designed to make workouts more interesting — for example, the ability to play DVD movies or virtual workouts (see above).

— Bluetooth. The presence of a Bluetooth wireless module allows the machine to be synchronized with the user's smartphone, tablet or laptop/PC. Thanks to data synchronization, the user will be able to control the resu...lts of training in a convenient form. Additionally, Bluetooth wireless communication can be used to download new training programs to the computer of the machine and synchronize with the heart rate monitor via the ANT protocol.

— Wi-Fi. The presence of a Wi-Fi wireless communication module in the design of the machine. The Wi-Fi interface was originally intended for connecting to computer networks (including Internet access), but more recently it has also been used for direct connection between different devices, without using a network. The specific features implemented using this module may be different. So, some cross trainers can interact with training programs installed on tablets and smartphones and transmit information to such programs about the details of the training (distance travelled, calories burned, etc.), while others allow you to update the firmware or change the settings remotely, etc.

— USB port. USB itself is a universal interface designed to connect external peripherals to a computer or other control device. Actually, for the same purpose it is used in modern machines; but the specific application in different models may be different. So, USB can be used to connect heart rate sensors and other specialized accessories, to play music and/or video from a USB drive, to update the firmware using the same USB drive, etc.

— TV tuner. The presence in the design of the machine of a TV tuner — a device designed to receive television broadcasts. This function is useful for those who would like to be able to watch their favourite TV programs, series, etc. right in the process of training: usually, models with TV tuners also have colour displays and speakers (see below), which allows you to watch the broadcast directly on the machine's display. However, one needs to remember that tuners can be designed for different broadcast standards; therefore, before purchasing a model with this function, it is advisable to make sure that it is compatible with local TV broadcasts.

— mini-jack 3.5 mm (Aux). The 3.5 mm mini-Jack (Aux) connector is designed to connect an MP3 player or a smartphone/tablet. Thanks to this, it is possible to output a sound signal from multimedia devices to the speakers built into the cross trainer. Some models may additionally have a mini-jack connector for connecting headphones. The sound output to the headphones will allow you to train to your favourite music without disturbing other people in the same room.

— Speakers. The presence in the design of the cross trainer of speakers. They can play music, the sound of a movie playing on the display (see "Colour display"), as well as various service messages — for example, a warning about exceeding the maximum heart rate.

— Tablet stand. It allows you to securely and safely mount a tablet with almost any screen size on the cross trainer. Thanks to this, the user can enjoy watching TV shows or movies directly during training. Usually, the stand is located under the main screen of the machine. Advanced class models are often equipped with a stand with the ability to adjust the angle of the tablet.

The type of power source used in the cross trainer.

— Mains. Cross trainers are powered by a standard 230 V power supply. Such power allows you not to worry about replacing or recharging dead batteries — the machine will work as long as there is electricity in the house. In addition, it is suitable for machines with any load system, even electromagnetic (for more details, see "Load system"), while such models are much cheaper than similar generator ones (see below). The main disadvantages in this case are the dependence on the outlet and the need to use a power cord, which can limit mobility and get in the way. However, in most cases, these shortcomings do not cause significant inconvenience.

— Battery. The cross trainers are powered by batteries. The main advantage is the autonomy of the machine — it can be installed anywhere without worrying about the presence of sockets and laying the power cord. On the other hand, the battery power is very limited, and they are only suitable for cross trainers with mechanical or magnetic load systems (see "Load System" for more details), where only the computer needs power. In addition, the battery life is not infinite, and they need to be changed or recharged periodically.

— Built-in generator. The cross trainers are powered by a built-in generator, which is driven by the rotation of the flywheel. In othe...r words, when using such a model, the user himself generates the energy required for work. To turn on the generator simulator, it is enough to turn the flywheel several times. This type of power supply combines the advantages of the two above. On the one hand, it is autonomous, on the other hand, it has sufficient power even to provide energy to electromagnetic load systems (for more details, see "Load system"). And you won’t have to change anything, unlike batteries, because the service life of the generator is comparable to the service life of the machine itself. At the same time, this feature significantly increases the weight, and most importantly, the cost of the cross trainer, and therefore is found only in premium-class models.

The dimensions of the equipment in the assembled and ready-to-work state. It is important to note that more space is needed for the comfortable and proper operation of the machine.
