| Summary: | Electric bicycle is a vehicle which is used widely in all the citys and provinces
of Vietnam. However, it’s hard to choose “the most suitable” or “the best”
type of electric bicycle because each type has different criteria
(parameters). To choose out the best option, we need to consider all the
alternatives at once. That is called multi-criteria decision-making. This
research used three multi-criteria decision-making methods include SAW
method, MARCOS method and PSI method to choose from seven bestselling types of electric bicycle on the market in 2022. All the methods
which were used chose out the same best electric bicycle type and the same
worst bicycle type. And so, among seven types of electric bicycle which
include M133 mini, M133 Sport 2022, Aima 133AM, Nijia – PA4, DK 133M,
Yadea iGo and Yadea i3, the best type is Aima 133AM, in contrast, Yadea
iGo is considered the worst type. Things that need to be done in the
folowing researches were proposed in the last part of this paper.
