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.
Load levels
The number of fixed load levels (pedal resistance during movement) provided for in the design of the cross trainer.

At the same time, the abundance of adjustments accordingly affects the price.
Seat

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.
