Max. user weight
The maximum weight of the user for which the cross trainer is designed. This parameter should be adhered to as accurately as possible, do not be mistaken about the fact that 3-5 kg over the calculated weight will not affect the device. Yes, most likely, the simulator will be able to work for some time, but it will experience loads exceeding the calculated ones, and at best it will fail earlier than expected, and at worst it may break at the most unfortunate moment, which is fraught with injuries. In addition, this case is usually not covered by the manufacturer's warranty, and you will have to eliminate the consequences at your own expense.
Seat
The presence in the design of the cross trainer
seats. It is similar to what is used in exercise bikes. The main purpose of this function is the possibility of using the unit as a "bicycle". Most likely, such a model will not replace a specialized exercise bike, but the seat significantly expands the scope of use of the cross trainer.
Power source
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.Dimensions
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.
