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.
Load levels
The number of fixed load levels (pedal resistance during movement) provided in the design of the exercise bike. The more such levels provided in the design, the wider the possibilities for adjusting the load and the more accurately it can be adjusted to the requirements of a particular user. At the same time, the abundance of adjustments accordingly affects the price.
Training programmes
The number of training programmes provided in the design of the exercise bike. Different programmes have different purposes — strengthening the cardiovascular system, maintaining physical fitness, burning fat, etc. At the same time, the operation of the programme relieves you of the need to manually set and change the parameters — this is what the exercise bike does. Accordingly, the more training programmes a particular model has, the wider its capabilities and the more convenient the training. And in some cases, it may even provide the possibility of custom programmes .
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.
