Comparison Hop-Sport HS-2070 Onyx vs Hop-Sport HS-2080 Spark

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 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.

The presence of height-adjustable legs-stands in the design of the exercise bike. Each of these legs is independently adjustable. This allows you to compensate for uneven floors and stably install the device in a horizontal position.

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

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

— Bottle holder. The presence of a special rack in the design of the exercise bike, on which you can put a bottle or a 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 the workout on the exercise bike.

— Colour display. The presence of a colour screen in the design of the simulator. This feature does not affect the main features of the device. However, such displays are considered more convenient and pleasant to view than monochromatic ones. 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 in the exercise bike allows the exercise bike to be synchronized with the user's smartphone, tablet or laptop/PC. Thanks to data synchronization, the use...r will be able to control the results of training in a convenient form. Additionally, Bluetooth wireless communication can be used to download new training programmes to the on-board computer of the exercise bike 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 exercise bike. 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 exercise bikes can interact with training programmes installed on tablets and smartphones and transmit information to such programmes about the details of the training (distance travelled, calories burned, etc.), others allow you to update the firmware or change the settings remotely, etc. .P.

— 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 exercise bikes; 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 exercise bike of a TV tuner — a device designed to receive television broadcasts. This feature is useful for those who would like to be able to watch their favourite TV programmes, series, etc. during the training: usually, models with TV tuners also have colour displays and speakers (see below), which allows you to watch the broadcast directly on the exercise bike. However, 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, you can get the sound signal from multimedia devices to the speakers built into the exercise bike. 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 users in the same room as you.

— Speakers. The presence in the design of the exercise bike of its 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. Allows you to securely and safely mount a tablet with almost any screen size on the exercise bike. 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 simulator. Advanced models are often equipped with a stand with the ability to adjust the angle of the tablet.

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.
