Explanation:

Emphatic forms of verbs are used to emphasize what is expressed by the verb. This is accomplished by the use of the auxiliary verb to do. There are two emphatic tenses: the present and the past emphatic tense. Depending on the tense, a fitting form of the verb to do (do/does for present tense, did for past tense) is used together with the base form of the verb. For example:

He does like reading. (Instead of simply He likes reading.)

He did do his homework. (Instead of He did his homework.)

The same form is present in the sentence We do wear helmets when we bike together, as a rule. (Instead of We wear helmets when we bike together, as a rule.)
