Wheel size
tThe diameter of the wheels used in the vehicle. For models with wheels of different sizes, the largest diameter is usually indicated, other data can be specified in the notes.
For electric scooterbikes, the traditional size is a modest 10"; larger sizes are also found — up to
16". Among minibikes, large
18" wheels are more common. Electric motorcycles have small wheels — an average of 12 – 14". Among electric tricycles, a combination of a large front wheel with small rear wheels is often found — for example, 16 "and 4" each, respectively.
The large diameter allows you to roll over the bumps on the road, overcome rather large obstacles and maintain speed longer when coasting; on the other hand, such wheels require more torque from the engine, they accelerate worse and reduce the maximum speed of the unit. Small wheels, on the contrary, accelerate well and also provide good manoeuvrability, but they are intended mainly for flat roads.
More features
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.Battery capacity
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.
Weight
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.
