I've seen that there is even a "sticky" topic now with the grammar notes.
'ber-' prefix is not on that list.
It's probably already explained in the original Tips&Notes.
(the lightbulb icon)
Long story short....'ber-' prefix can have the following meanings :
"to have" , "to use , "to produce".
(please check/doublecheck with the Tips&Notes)
Saya bersepeda. (I use the bicycle ==> I bike/I cycle !?)
Saya beranak. (I have a child / I give birth to a child)
Not sure about the bicycle (to cycle ???) (is that a verb in English ?).
But that's how the ber- prefix is used in Indonesian.
To form a verb from other words (mostly nouns).
