[Modification]
In the first and second embodiments described above, electronic component 48 includes transmission 50 . However, as shown in FIG. 7, electronic components 48 include at least one of transmission 50, suspension 56, adjustable seatpost 58, braking device 60, lights 62, display device 64, and assist drive device 66. good too. The suspension 56, adjustable seat post 58, brake device 60, light 62, display device 64, and assist drive device 66 are of conventional construction and will not be described in detail.

As used herein, "comprising" and its derivatives are open-ended terms describing the presence of elements and do not exclude the presence of other elements not listed. This also applies to the words "having", "including" and their derivatives.

The terms "member", "part", "element", "body" and "structure" can have multiple meanings such as single part and multiple parts.

Ordinal numbers such as "first" and "second" are merely terms to identify configurations and have no other meaning (eg, a particular order, etc.). For example, the presence of a "first element" does not imply the existence of a "second element", nor does the presence of a "second element" imply the existence of a "first element". does not imply that

As used herein, the term "a pair of" includes both a pair of elements having the same shape and structure as well as a pair of elements having different shapes and structures.

As used herein, the phrase "at least one" means "one or more" of the desired option. As an example, the phrase "at least one" as used herein means "only one option" or "both of the two options" if the number of options is two. As another example, the expression "at least one" used herein means "only one option" or "any combination of two or more options" if the number of options is three or more. means For example, the phrase "at least one of A and B" includes (1) A only, (2) B only, and (3) both A and B. The phrase "at least one of A, B, and C" means (1) A only, (2) B only, (3) C only, (4) both A and B, (5) B and C (6) both A and C; and (7) all A, B and C. In other words, in this disclosure, the phrase "at least one of A and B" does not mean "at least one of A and at least one of B."

Terms such as "substantially," "about," and "approximately" expressing degree can mean a reasonable amount of deviation such that the final result does not change significantly. All numerical values set forth in this application may be interpreted to include words such as "substantially," "about," and "approximately."

Obviously, many variations and modifications of the present invention are possible in view of the above disclosure. Accordingly, the present invention may be practiced otherwise than as specifically disclosed herein without departing from the spirit of the invention.
