Comparison Rover Ampere vs BRAVIS Grace

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.

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.

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.

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.

A cargo element in the form of an open platform, mounting frame, or closed box, designed for transporting items. Luggage rack is useful for daily trips, delivery, carrying a helmet, raincoat, or small purchases.
