4.1. Evolution of Scientific Production
From 1973 to 2017, the search yielded 896 report results, whose temporal distribution is exhibit in Figure. It ought to be cited that the search has no records prior to this date, for this purpose 1973 is regarded the first yr of this search. It is discovered that the amplify starts in 2003, and 2008 is the yr when scientific manufacturing will increase significantly. These publications are written basically in English in greater than 90% of cases, even though the Chinese language additionally seems strongly because 2001,with 7.5%, different languages are already anecdotal with much less than 1% and covered Japanese, Dutch, German, Polish, Russian, Spanish, and French.
Evolution
of the scientific production in relation to the electric bicycle
(1973-2017)
In the evaluation of the capability of scientific diffusion, generally, the most used capability are journal, besides in areas of novel research, the place the search phrases show up normally in specialised scientific conferences. This is what takes place in our case, the place convention papers account for the most part, 54% of the total, whilst articles in journals account for 43%. Figure suggests the proportion of the kinds of scientific manufacturing disbursed on the theme of electric powered bicycle.

4.3. Keyword Analysis
The evaluation of the key phrases identifies or summarizes the work of the researchers .
This area analyses the key phrases received from the principal question described in the methodology
section. In the normal articles got from the query, the frequency of look of every key-word has been obtained. In Figure , a phrase cloud has been represented the place dimension and centrality exhibit the significance of that key-word inside the complete publications, described through the very best frequency of incidence or the range of instances it is repeated. If the predominant question is filtered by way of every of the most important international locations by way of wide variety of publications, the predominant key phrases of these nations are obtained. Therefore, the three foremost key phrases of the pinnacle ten countries. The key phrases of the international locations that least resemble the relaxation are these of Japan and Australia, and each have a gender factor that is very an awful lot current in their studies.
On the different hand, if the principal search is confined to a unique keyword, the frequency of occurrence of this key-word for every 12 months can be obtained. Figure indicates the evolution over time of the pinnacle three keywords. Note that the search is restricted to the closing ten years, from 2007 to 2017. This is due to the small distinction current in before years (note that in 2007 two of these key phrases had no values). The key phrases “Electric Vehicle” have been nearly constantly above the others however they have emerged typically considering the fact that 2015. The different two keywords, “Sporting Goods” and “Transportation”, had been in the equal rank till 2012. Since then, wearing items started out to distance itself upwards. In this phase of the analysis, it is well worth noting that the electric powered bicycle is no longer simply an choice for transportation, however a potential of every day sports activities exercise to enhance health. Indeed, the electric powered bicycle is viewed a vehicle. It is essential to spotlight this fact, due to the fact for many international locations it is proposed as a answer to the hassle of non-public transport. On the different hand, in the US, “sporting goods” refers to gadgets that are bought for leisure purposes.

4.4. Analysis of the Interconnection Between Keywords: Community Detection
Considering a neighborhood as a gadget composed through a couple of interdependent elements, with
a very large vary of relationships that are variable and dependent, we ought to accept, conceptually, that communities are made up of a notably cohesive central core and peripheral spheres with unions increasingly more weaker in contrast to the center. The central core would be structured by way of the most large factors of the community, in phrases of granting a definable individuality, evinced by means of the hyperlinks between its ingredients who share the strongest and most sizeable connections inside the complete neighborhood complex. Communities or clusters are generally corporations that are greater probable to relate to every different than with individuals of different groups. Identifying communities is an fascinating trouble in our case due to the fact it will information us round which way the principal matters of the publications are grouped. For this particular analysis, we downloaded the key phrases of every book separately, producing a file line with up to six key phrases used in every publication; this file used to be entered into a community evaluation software program that detected the foremost communities.

Main keywords used by the
communities detected in the topic electric bicycle
Clusters with exclusive hues have been proven and they are represented in the structure of neural network. Each node is a keyword, and the thickness of the link between nodes is the frequency of that relationship. In the evaluation of the e-book of the electric powered bicycle, six communities have been detected the usage of a neighborhood detection algorithm, and Table three indicates their primary keywords. To perceive every cluster a proposed identify is presented in the ultimate column of the table. By order of significance they are: Transportation–Environment, Electrical engineering, Safety, Batteries, Sporting goods–Urban planning, and Mechanical engineering. Transport and surroundings is the first in order of importance, highlighting this cluster inside world research, and above all the challenge for air air pollution in cities.

Electric
bicycle Keywords network and their community detection
As used to be expected, electrical engineering helps this technology, and it is pretty logical that it ranks second. The hazard elements for accidents have improved significantly with the extend in the variety of electric powered bicycles, so the trouble of security seems as the 0.33 most vital issue. Batteries rank fourth amongst the clusters, highlighting the enchancment of batteries, specially in charging structures and the extend in their autonomy. As noted above, it is stunning that the electric powered bicycle is phase of the thinking of sport, however its every day use surely promotes person sport, and this can be a fitness improving sports activities routine. The mechanical method is consequently the remaining of the categories.
