Comparison Ninebot E Plus vs IPS Zero

— Hoverboard. Such a vehicle is a board with a pair of wheels (one at each end). The hardware of the hoverboard includes a balancing system that allows the rider to stand steadily on such a platform. The board itself is divided into two platforms, separately for each leg. The hoverboard is controlled by slightly tilting the platforms forward or backwards, while each of them controls its wheel, causing it to rotate in the appropriate direction. Thus, to go forward, you need to slightly tilt your legs on your toes; to go back tilt on your heels, and by tilting the platforms in different directions, you can even spin in place. Such equipment usually does not have a clearly defined front and back side; it drives the same way in any direction. Moving on a hoverboard requires certain skills and attentiveness, but it is not as difficult as it might seem at first glance. At the same time, the apparatuses themselves are quite light and compact — the dimensions of many models are comparable to not the largest skateboards.

— Hoverboard with handle. A variety of self-balancing vehicles, colloquially called "segways" — by the name of the Segway company, which first introduced a successful model of such a vehicle to the market. By design, such vehicles are generally similar to the hoverboard described above — they have a platform for legs, two wheels and a balancing system. The key difference is primarily the...handle (steering column) mentioned in the title. It is vertical and is usually located in the middle of the platform, while its length can be different — most often it is supposed to hold on to the upper end of the handle with your hands, but there are also compact models where it is clamped between the knees. In addition, the hoverboard with handle may have a slightly different control method: the platform is often made in one piece, without dividing into halves for the left and right legs, and is only responsible for moving back and forth, while turns in such models are carried out by tilting the steering rack. Anyway, the handle provides additional support, making riding such a hoverboard somewhat easier and safer than a classic one (especially at high speeds). On the other hand, devices of this type are noticeably more expensive, heavier and more bulky than models without handles. As a result, if an ordinary hoverboard can be easily hidden in a backpack, then the hoverboard with handle will most likely have to be transported in the car boot.

— E-unicycle. Further development of the idea of self-balancing transport, units equipped with only one wheel — like unicycle bicycles, only with an electric drive. The wheel in such devices is covered with a case containing electronic and mechanical hardware; and foot platforms are located on both sides of the wheel, usually below the axle, and are often made foldable for compact storage and transportation. The design usually does not include a front/rear side. Maintaining balance on an e-unicycle is easier than on a unicycle bicycle, but it can be more difficult than on a hoverboard. Riding requires carefulness: hitting even a low obstacle can lead to a fall forward (the weaker the e-unicycle motors, the higher the likelihood of such an accident). However, the described points can also be perceived as advantages (or neutral features), and this vehicle also has its adherents, and the maximum speed of an e-unicycle can be quite high (although, of course, protective equipment is required for a safe ride).

The maximum rider weight that the device can support (including the weight of a backpack, bag and other things carried on oneself; this is especially important to remember if the weight of the person himself is close to the maximum allowable). If the permissible load is exceeded, the transport not only loses efficiency but can also break down at any time. Therefore, it is impossible to ignore the prescriptions for weight anyway.

The average distance that can be driven on a single battery charge. Usually, the range is indicated with some overestimation — based on a low (optimal from the point of view of energy consumption) speed, uniform movement on a flat surface, etc. Therefore, the actual battery life may be somewhat less. Nevertheless, this parameter is quite suitable for comparing different models with each other.
Thanks to the development of technology, the range in modern self-balancing vehicles can reach several tens of kilometers.

The maximum speed that the hoverboard is capable of reaching: on a flat surface, with a full battery charge and an average rider weight. The same parameter is also the maximum safe speed allowed when using this model; in theory, it is possible to accelerate even faster (for example, from a mountain), but this is fraught with breakdown, accident and injury, and therefore is not recommended at all.

Most modern models have a maximum speed of up to 20 km/h, and in “high-speed” vehicles this figure can exceed 30 km/h. Note that a fall from a hoverboard, even at a speed of 10 – 15 km/h, is fraught with serious injuries. Therefore, protective gear is highly recommended.

The diameter of the wheels used in the vehicle. Technically, larger wheels contribute to rolling ability and reduce sensitivity to obstacles and small bumps. However, these possibilities are influenced by many other factors, not least the engine power: with a weak engine, the unit may not have time to cope with the obstacle, which will lead to the rider falling forward. Therefore, large wheels must be combined with a powerful engine.

By itself, information about the diameter of the wheel can be useful when repairing or replacing it.

The height of the handlebar provided in the design of the hoverboard with a handle (see "Product type") — other types of self-stabilizing vehicles are not equipped with it. The handlebar should have such a height that it is convenient to hold on to it with your hands (or clamp it between your knees, depending on the design features). At the same time, manufacturers rarely indicate this parameter: it is understood that the length is optimally selected for adults, taking into account the possible difference in physique. In addition, many handlebars are made adjustable; in this case, the maximum height is given.

The maximum angle of inclination of the surface at which the vehicle can normally drive up or down (in some models, this parameter is indicated only for one direction, for example, up).

This parameter characterizes the ability of the device to overcome ups and downs. In modern models, it can reach 45 °. At the same time, note that the ability to cope with large angles requires not only powerful motors, but also appropriate design features (in particular, so that the protective cover does not scrape the ground); and for the descent, the second is even more important than the first. Therefore, when choosing a model for frequent driving on slopes, you should pay attention not only to power, but also to the angle of inclination directly stated in the specs.

Also note that at a high load (approaching the maximum), the efficiency of overcoming climbs may decrease. On the other hand, some manufacturers indicate the angle of inclination at the maximum load, and clarify that the light weight of the rider allows you to overcome steeper climbs than originally stated.

The battery capacity of the device in watt-hours (Wh).

In general, capacity shows the amount of energy that a battery can store. The higher the number, the more energy the battery stores, respectively, the greater the range (see above) and the more time it will take to charge. Note that although watt-hours are used to designate power much less frequently than milliamp-hours (see above), this designation is more reliable, because when evaluating capacity, in this case, the battery voltage is also taken into account (as opposed to counting in mAh). This makes it easy to compare batteries of different voltages. At the same time, do not forget that the energy consumption of different models can also be different, and battery life is easier to evaluate by the directly claimed range.

The power of the motor installed in the device. For models with two electric motors, this paragraph usually indicates their total power.

This parameter is one of the most critical for self-balancing transport. On the one hand, powerful motors improve the efficiency of balancing (especially with the large weight of the rider), allow you to reach high speed, effectively overcome bumps in the road and climb hills. On the other hand, they weigh a lot, are expensive and require capacious batteries to ensure a decent range (which further affects the weight and price of the entire unit). Therefore, motor power, usually, directly depends on the price category of a particular model.

In fact, the more powerful the motors, the better, and the question of choice for this parameter depends primarily on the price.
