Comparison AIMA Tiger vs Rover Element

The general type of vehicle determines the overall arrangement as well as some application specifics.

— Electric scooterbike. Vehicles of this type are outwardly almost indistinguishable from classic motor scooters. In particular, they have a relatively small footwell and a rather large ledge above the rear wheel; on this ledge is the seat, and inside is the motor. The only difference from classic scooters is that an electric motor is used instead of an internal combustion engine.

— Minibike. Minibikes are rather peculiar electric vehicles that look like slightly improved and weighted kick scooters: two very wide wheels, a platform for feet, a small seat and a handlebar. In terms of technical parameters, such as maximum speed and range, minibikes are not inferior to electric scooterbikes. However, low ground clearance and modest depreciation make minibikes demanding on the road surface, and the absence of turn indicators in most models makes them unsuitable for highways. The perfect options for such transport are parks, pedestrian and bicycle zones, narrow streets of the historical centre and other similar locations.

— Electric motorcycle. Such vehicles differ from traditional motorcycles only in the use of electric motors instead of internal combustion engines. Like traditional motorcycles, they can be of different types and have differ...ent specializations — in particular, among electric motorcycles there are enduro and cross models.

— Electric car. Electric cars are similar in design to cars: they have 4 wheels, an enclosed interior, appropriate controls (steering wheel, pedals) and seats. The main difference from full-fledged cars (including electric ones) is their miniature size: units of this type are often designed for one or two passengers with a minimum of luggage (although there are also larger models). However, in many countries, according to the SDA, such vehicles fall under the category of cars. Electric cars are noticeably more expensive than other electric vehicles, but they also provide the appropriate comfort: you do not need to keep your balance, and the closed cabin protects the driver from bad weather.

— Electric tricycle. Quite a rare category of electric transport. Electric tricycles, by the name, have three wheels; but otherwise, they are usually similar to the minibikes described above — the design has a large platform and a relatively small seat. The three-wheel layout makes such units very stable, they do not require kickstands, and the design most often has a basket on the front. At the same time, for several reasons, electric tricycles are not very common.

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 motor power of a vehicle, in kilowatts. In addition to them, horsepower is also used (for more details, see above).

Let us clarify that in this case, we are talking about maximum power; the actual power can be adjusted while driving with the help of the accelerator. And in some models, it may even be possible to set a limit on the maximum power.

A more powerful motor allows you to carry more weight, reach higher speeds and/or have more torque. However, the energy consumption from the battery will also be high, and the battery life, with the same battery capacity, will be correspondingly less than when using a less powerful motor. Also note that in many countries, motor power is a criterion for classifying an electric vehicle as one or another variety. For example, according to this criterion, motorcycles and scooters can be formally separated, requiring different driving licences.

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.

— 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.

— Lead-acid. The most popular type today. Their design is based on a combination of electrodes made of lead compounds and an electrolyte, the role of which is played by sulfuric acid diluted with water. It is the classic type of batteries that use a conventional liquid electrolyte. Their widespread use is due to their simple design and low cost, combined with good capacity and starting currents characteristic of all lead-acid batteries, as well as resistance to low temperatures (compared to other types of batteries).

— Lithium-ion (Li-Ion). Lithium-ion technology was originally used in batteries for portable gadgets such as mobile phones, but such batteries are being used more and more recently in vehicles. Among the advantages of such batteries, one can note smaller dimensions and weight, the ability to deliver high starting currents and the ability to be charged with high currents (the latter significantly reduces the charging time), as well as numerous charge-discharge cycles. In addition, such batteries contain a minimum of harmful substances, do not use acids and heavy metals, and some models are even directly positioned as absolutely harmless to the environment. The main disadvantage of lithium-ion models is the high price.

— Gel. A type of lead-acid battery in which the electrolyte is not liquid, but condensed to a gel state. This design prov...ides several advantages compared to the classic version (see above): more charge-discharge cycles (which means longer service life); minimum leakage of electrolyte and associated gases; no need for maintenance; resistance to deep discharges and temperature fluctuations, etc. On the other hand, such batteries cost significantly more.
