Wheelbase
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.
Power
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.
Number of motors
The total number of electric motors installed in the vehicle.
In the vast majority of modern electric vehicles, a single motor is used for the entire unit. This option is considered optimal in terms of several parameters: dimensions, weight, cost, simplicity of design, etc. There are almost no exceptions to this rule.
Battery capacity
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.
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.
