Comparison Yadea S-Way vs Yadea EM215

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.

Speed modes allow you to limit the maximum speed of an electric scooter or moped for different riding conditions. With 2 modes, there is usually a calm and a faster option, with 3 modes an additional convenient medium level is added for the city, and 4 modes provide more precise customization for the yard, sidewalk area, regular road, or economical riding.

The more modes, the easier it is to balance speed, battery consumption, and safety. For example, the low mode is convenient for parking and moving next to pedestrians, the medium mode is for everyday trips, and the maximum mode is for open road sections.

— 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.

A charging port for a smartphone, navigator, or another small gadget directly from the battery of an electric scooter or electric moped. Typically, such a port is located near the handlebars or on the panel, so the cable does not interfere with riding, and the gadget can be conveniently placed within view.

This feature is useful for couriers, traveling on unfamiliar routes, and daily use of navigation. It is important to note that the USB port is usually designed for low power, so it is suitable for charging gadgets rather than powering large devices.

Wheelbase of the vehicle.

This term shows the distance between the wheels, more precisely, between the axles of the wheels. This size is one of the key parameters for any motorcycle, it determines not only the overall dimensions of the vehicle but also some of the features of the movement. So, a small wheelbase reduces the turning radius and makes the vehicle more manoeuvrable; at the same time, a longer vehicle will be more stable and predictable in corners.

The total weight of the vehicle without cargo and rider.

The lighter the unit, the greater the range and, accordingly, the weight of the payload that can be carried on it. On the other hand, too little weight adversely affects the stability, and sometimes the overall strength of the structure.
