Comparison AIMA Journey King E vs AIMA Power Eagle

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 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 maximum incline that the vehicle can overcome.

Most vehicles, even the most inexpensive ones, can cope with angles of 10 – 12 ° without problems. So you should pay special attention to this parameter only if you have to deal with very steep slopes.

It is also worth mentioning that on road signs the angle of elevation is usually indicated not in degrees, but as a percentage. This means that to evaluate the capabilities of a particular unit, it may be necessary to convert degrees to percentages or vice versa. For this, there are special tables and calculators.

— Rubber Inflatable Tubeless. Tires without an inner tube, where the air is held by the tire itself on a sealed rim. They comfortably handle small bumps, tiles, and poor asphalt, and they better withstand small punctures: pressure usually doesn't drop immediately, and the rider often manages to reach a repair point. Unlike tubed wheels, they are less dependent on the condition of the tube and require less frequent replacement. However, they are more demanding in terms of rim quality and installation, making this type more common on practical city electric scooters, where reliability and daily use convenience are important.

— Rubber Inflatable. In the classic sense, they have a separate tube inside the tire that retains air and cushions road shocks. In terms of comfort, they are close to tubeless, making them well-suited for riding in yards, on tiles, uneven asphalt, and suburban areas. The main difference from tubeless wheels is their behavior when punctured: the tube usually loses pressure faster, but it is simpler and cheaper to patch or replace. This option is often found on affordable electric mopeds and electric scooters, where smoothness, simple construction, and inexpensive maintenance are important.

The front brake in an electric scooter or electric moped is responsible for the main part of deceleration, as the weight shifts forward during braking. Its efficiency affects not only the braking distance but also the rider's confidence during sudden stops, downhill descents, or riding with a passenger.

— Disc. The disc brake consists of a brake disc and pads that clamp it from both sides. It is considered a more effective solution for the front wheel as it responds faster to the lever press, better withstands heat, and provides clearer braking force. This option dissipates heat better, allows for more precise modulation, and works more effectively on more powerful electric scooters, especially at high speeds, with frequent stops, and for urban riding.

— Drum. The drum front brake is located inside the wheel: the pads expand and press against the inner surface of the drum. It is simpler, cheaper, and better protected from dirt, but generally inferior to the disc brake in terms of sharpness and stability during active braking, so it is more commonly found on lightweight electric mopeds and calm urban models.

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.

Additional features provided in the design of the vehicle.

— Headlight and position lamps. Lighting devices are designed to ensure safety at night and in conditions of low visibility. Position lamps are used to highlight the vehicle on the road, the headlight can also perform this function, but its main task is to illuminate the road in front of the vehicle. In most countries, traffic rules prohibit driving on roads in the evening and at night without headlights and headlight and position lamps. Note that such lighting devices can be purchased and installed separately. However, it is easier to immediately purchase transport, where it was originally provided.

— Turn signals. Standard turn signals are yellow or orange and are installed on both sides of the unit. Recall that according to the rules, it is necessary to indicate turns and lane changes; without light indicators, such signals have to be given by hand, removing it from the handlebar — which is not very convenient, and sometimes unsafe. Turn signals also simplify the task — to turn on the signal, just press a button or slide a switch.

— Horn. Special sound signal. The sound signal is intended primarily to warn other road users and prevent accidents.

— Anti-theft system. Security system to prevent vehicle theft. Note that the specific way the anti-theft system works in...different models may be different, it should be specified separately. In some cases, it is limited to notifications sent to the key fob or mobile phone that the thief is trying to move the vehicle. In other devices, the protection system can physically prevent theft — for example, by locking the steering or brakes.

— Carrier. Only containers installed in the rear of the vehicle are referred to as the carrier — a basket on the handlebar can be used in the front (see the relevant paragraph).

— Handlebar basket. A small basket is located on the handlebar of a vehicle. It is similar to the carrier (see the relevant paragraph) and is intended for the transport of various items. However, note that it is impossible to carry a lot of weight on the handlebar, this worsens stability and manoeuvrability. However, baskets usually have a small volume anyway.

— Kickstand. It is a small stand in the lower part of the body, which is laid out during parking and allows the unit to stand stably in an upright position. This function is relevant only for two-wheeled vehicles.

— Pedals. In this case, we are talking about pedals like bicycle pedals, which are placed under the driver's feet. This feature can be extremely useful in emergencies — for example, if the battery was forgotten to be charged or it discharged in the middle of the trip, if there was a malfunction in the electronics, or if it is far from charging and the battery needs to be saved. Another way to use the pedals is to assist the motor in difficult conditions, such as when driving through mud or on a steep slope.
Note that pedals are not used in minibikes — not because of difficulties of installation, but as unnecessary: in extreme cases, you can ride on such transport like on a kick scooter, pushing off the ground with your foot.

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.
