Comparison Rover Dragon 05 vs AIMA Journey King E

The maximum additional weight that a vehicle is designed to carry is, in fact, the weight of the payload that it is allowed to carry.

The maximum load includes both the passenger himself and the things he carries. In this case, the value is usually indicated based on a flat road and a quiet ride. So, ideally, it is best to have a maximum weight margin of at least 10-15 kg — this will give an additional guarantee in case of emergencies, such as a wheel falling into a pothole.

The range of a vehicle is the distance it can travel on a single battery charge.

Note that the range usually indicates the value for perfect operating conditions: driving at optimal speed with a small load, flat road, no ups and downs, etc. The actual range may differ from the claimed one, sometimes quite noticeably. In addition, to improve range, manufacturers can deliberately use low-power motors that consume little energy.

The motor power of a vehicle, in horsepower.

In general, the power of electric motors is indicated in watts. However, in electric transport, this designation is also often indicated. This is done for the convenience of comparison with internal combustion engines: for internal combustion engines, especially in vehicles, horsepower is traditionally used, and it is more convenient for some users to evaluate the power of motors by this designation. At the same time, if the need arises, some units are easily converted to others: 1 hp. ≈ 735 W.

For the power value in general, see the relevant paragraph below.

The highest speed that a vehicle can reach.

When choosing according to this parameter, it is worth considering that in dense city traffic, it is rarely possible to accelerate faster than 40 km/h; so if the vehicle is bought mainly for a comfortable ride through traffic jams, then there is no need to look for a high-speed model. In addition, for the same motor power, low speed means more torque, which makes it easier to climb hills.

The rear brake on an electric scooter or e-moped helps stabilize the vehicle when decelerating and complements the front brake. It is especially useful at low speeds, for smooth stopping, riding with a passenger, or on slippery surfaces where it's important not to overload the front wheel.

— Disc. A disc rear brake uses a brake disc and pads that quickly and confidently slow the wheel. This option is better suited for more powerful electric scooters as it withstands active braking, overheats less, and gives the rider more precise control.

— Drum. A drum rear brake has a closed mechanism inside the hub, making it well-protected from dirt, dust, and moisture. It is simpler and cheaper to maintain but usually less effective during sharp braking, so it is more commonly found on lightweight e-mopeds and models for relaxed city riding.

The capacity of the battery installed in the vehicle, in ampere-hours.

Theoretically, the battery life of the vehicle directly depends on this parameter: a more capacious battery can supply the electric motor longer. However, the actual amount of stored energy depends not only on the capacity in amp-hours but also on the nominal voltage of the battery. A more correct unit in this sense is watt-hours, taking into account the difference in nominal voltages; see "Battery capacity" below for details on this designation. Additionally, the operating time on a charge will depend not only on the characteristics of the battery but also on the power consumption of the vehicle itself — and it is determined by the motor power and several other parameters.

The capacity of the battery that is installed in the vehicle, in watt-hours.

To correctly compare batteries of different capacities and voltages, the designation in watt-hours is used. In addition, such a designation is convenient for estimating the operating time on a charge: for example, with an engine power of 2 kW, a battery of 3000 Wh is enough to power it at maximum power for 3000/2000 = 1.5 hours.

As for the capacity of the battery as a whole, theoretically, the battery life of the vehicle directly depends on it. However, the operating time will also be determined by the power consumption of the unit itself — and it is influenced by both the mentioned motor power and several other parameters.

The time needed to charge the vehicle battery from 0 to 100%.

This parameter allows you to estimate what breaks you will have to take between trips to charge the vehicle. But keep in mind that a short charging time may mean a low battery capacity.

Separately, we note that in modern battery technology, “emergency” charging technologies can be used, which make it possible to partially replenish the energy supply in a very short time — for example, to charge a battery by 40% in an hour, which in normal mode would be fully charged in 8 hours.

An anti-theft security system for preventing vehicle theft. It is worth noting that the specific operation method of the anti-theft system may vary across different models, so it should be clarified separately. In some cases, it is limited to notifications sent to the key fob or mobile phone alerting that the vehicle is being moved. In other models, the protection system is capable of physically preventing theft — for example, by locking the steering wheel or brakes. Also, note that a key ignition start system in itself is not considered an "anti-theft system" in this instance.
