Max. user weight
The maximum user weight for which the exercise bike is designed, in other words, the maximum weight of the athlete, at which the unit is guaranteed to work for the amount of time stated in the characteristics without the risk of breakage. 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 exercise bike 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.
Flywheel weight
The weight of the flywheel installed in the exercise bike — a massive wheel, the rotation of which provides the movement of the pedals and creates a load on them. It is believed that the more weight, the better: a massive flywheel provides smooth movement and creates uniform loads that mimic natural ones as much as possible. This will be especially useful for athletes with a large body weight — from 100 kg and above — especially when working on vertical machines (see "Type"). At the same time, the cost of the entire device directly depends on the weight of the flywheel, and for home non-professional use it is not always justified to look for an exercise bike with a very heavy wheel.
Handlebar adjustment
Handlebar adjustment usually implies the possibility of changing the angle of its inclination and, accordingly, the distance between the handlebars and the seat. Thus, each athlete can set the distance that is most convenient for him to avoid unnecessary stress on his arms and back.
Power source
The type of power source used in the exercise bike.
—
Mains. Powered by a standard 230 V power supply. Such power allows you not to worry about replacing or recharging dead batteries — the exercise bike will work as long as there is electricity in the house. In addition, it is suitable for models with any load system, even electromagnetic (for more details, see "Load system"), while such devices are much cheaper than models with generators (see below). The main disadvantages are the dependence on the outlet and the need to use wires, which can limit mobility and get in the way. However, these shortcomings do not cause significant inconvenience.
—
Battery. The exercise bike is powered by replaceable batteries. The main advantage such exercise bikes can be installed anywhere without worrying about the availability of sockets and laying the power cord. On the other hand, the power of the batteries is very limited, and they are only suitable for models with mechanical or magnetic load systems (see "Load system" for more details), where power is required only for the computer. In addition, the battery life is not infinite, and they need to be changed or recharged periodically.
— Built-in generator. The exercise bike is powered by its built-in generator, which is driven by the rotation of the flywheel. In other words, when using such a model, the user himself generates the energy
...required for work. To turn on the exercise bike with a built-in generator, 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"). At the same time, this feature significantly increases the weight, and most importantly, the cost of the device, and therefore is found only in premium models.Dimensions
The dimensions of the assembled equipment. It is important to note that in fact more space is needed for the comfortable and proper operation of the exercise bike.
