An electric scooter is a two- or three-wheeled vehicle driven by the transformation of electrical energy into mechanical energy. The transfer is made due to the wheel engine - Shkondin wheels. The motor wheel is powered by a built-in battery and can act as a generator of electrical energy. Such scooters can be equipped with additional metering devices and control mechanisms. One of the leading companies selling adult and children's scooter vehicles is Jack Hot.
Characteristics
Scooter Jack Hot on a set of technical specifications belongs to the middle class of devices of this type. The main technical parameters of the models:
- maximum speed - 25-30 km / h .;
- range - 40-50 km;
- carrying capacity - 100–125 kg;
- dead weight - 7–9 kg;
- battery voltage - 24 and 36 v;
- capacity - 9.6 Ah.
These parameters are indicated in the ranges averaged for all Jack Hot models, as they may differ for different modifications. Also, depending on the production batch, the accuracy of the technical data of devices may vary even within the model range.
The maximum speed developed by the Jack Hot electric scooter can only be achieved under appropriate conditions. Of particular importance in this case is the quality of the road surface. Such a scooter is designed to move on a flat hard surface, as it does not have a reserve of high power and sufficient torque. In everyday operating conditions it will be difficult to achieve an indicator of maximum speed without the risk of an emergency and a threat to human health.
If the safety precautions and intensive use of the device on unsuitable road surface are not observed, despite the presence of a safety margin, it may fail. The occurrence of structural damage during movement can also lead to a situation that is dangerous to life and health.
The maximum range depends on the capacity of the battery, the degree of its charge and the nature of the terrain along which the scooter will move. Different model names can be equipped with batteries of different capacities.
During operation, the battery’s energy intensity and its ability to accumulate and hold a charge may deteriorate, which will lead to a decrease in the range.
Most modifications of Jack Hot scooters do not have a suspension. This significantly reduces the level of comfort during operation and reduces functionality. To compensate for the absence of a softening factor when moving on an uneven surface can carbon material from which the scooter deck is made.
Due to the properties of flexibility and elasticity, it can compensate for a certain number of vibrations passing through the frame of the structure, which is a big plus of the line of these devices.
Carbon deck has an acceptable margin of safety and resistance to deformation loads. However, the manufacturer stated a load limit. The limit of this indicator is also relevant due to the proportional decrease in controllability with an increase in weight load. Too much weight when maneuvering can lead to a pendulum effect. Concerning people weighing more than 100 kg are not recommended to use such an electric scooter.
The self-weight of the scooter allows you to simplify its transportation when folded. A low mass index makes it possible to carry it in your hands without significant effort.
The voltage and capacity of the batteries directly affect the speed of charging, the speed of movement and power of the device, as well as the formation of the price bar of the scooter.
Device
The stock model of the Jack Hot electric scooter company has two wheels, a deck with a flat footrest, a steering rack, a steering wheel, a battery, a lighting unit and additional complete accessories, the names of which vary depending on the model.
The front wheel is driving. Inside its rim is a wheeled electric motor. The wheel disc on the sides is protected by durable plastic covers, which protects the engine from dirt, dust and sand from the outside. On the wheel rim there is an elastic and durable rubber non-hollow tire, on which the tread pattern is applied. Through the sleeve, the drive wheel is connected to the fork of the steering rack.
The steering rack is vertical with only a slight bias towards the driver. It is made of durable aluminum alloy or carbon fiber. Inside the rack is a tubular battery. This solution avoids the use of additional wires and insulating materials, because the battery is located directly above the electric motor. There (on the steering column housing) is a connector for connecting the charger, which is equipped with a plug that prevents moisture and dust from entering it.
At the top of the rack is the horizontal steering wheel. In most Jack Hot models, the steering bar consists of two screwed onto a tube rail. When folding the scooter, the handles are dismantled by twisting. Such their arrangement and method of attachment avoids backlash and knocks during movement, as is the case with folding handles.
The front unit of the device (wheel and steering rack) are attached to the main part of the scooter - deck. The mounting mechanism is also folding mechanisms, which allows you to lower the steering rack to the deck and fix its position. When folded, the steering column and deck are parallel to each other.The fastener mechanism is equipped with Euro bolts with hexagonal sweat, which allows it to be completely disassembled for maintenance.
The deck is a flat foot pad with anti-slip coating. To increase its strength, stiffeners are provided. Width and length may vary depending on the model, but these differences are not significant.
The rear wheel is attached to the deck with a hub. It is made in the form of a cast chromed disk of various configurations. Just like the front, the rear wheel is equipped with a durable rubber tire that does not miss. To protect against splashing, a protective wing for the rear wheel is provided, which is also equipped with a brake function. To activate it, you need to press the wing with your foot, which is closer to the rear wheel.
The rear brake mechanism is not the only one. The front wheel block is also equipped with a regenerative braking system. This system works on the principle of returning electricity back to the system. Its function is as follows: when braking occurs (that is, the motor does not need to work to accelerate), the engine goes into generator mode and recharges the battery.
The latest models of Jack Hot scooters are equipped with a front suspension, which is made in the form of a spring with a vibration damper. Such an addition does not completely compensate for the vibration, but reduces the load exerted on the steering rack and all the mechanisms in it.
On the steering film is a display that provides an overview of data on speed, distance and battery charge. Most modern models have a round controller built into the upper end of the steering rack.
There are buttons on it or next to it, through which the device is turned on and its settings are made.
Reviews
Most user reviews of Jack Hot electric scooters come down to positive comments. This line of two-wheeled vehicles has a narrowly targeted area of use, however when used correctly, these scooters can become an indispensable addition and make life more comfortable.
Among the reviews of the owners there are also negative ones. Such characteristics do not relate to any implicit technical flaws, but only the mismatch between the capabilities of the scooter and the level declared by one or another user.
Each scooter is equipped with a specific charger of the corresponding electrical level. It is compact (like a laptop charger) and works on 220 v from the mains.
