The main advantages of an electric road bike are that it offers you the choice of doing a bit more—whether for commutes or rides—than with a classic bike, without forcing you into more demanding training, or of using it as a complement to traditional cycling.
Concretely, in the first case, opting for an electric bike will allow you to better tackle different types of terrain and cover longer distances without extra fatigue. This makes it ideal for those who want to get into sports without overexerting themselves, who want to ride with more experienced cyclists but don't have the same physical condition due to lack of time for intense practice.
