'Radweg' (bike path) is a compound noun made from 'das Rad' (short for bicycle) and 'der Weg' (path/way). So it is literally a 'path for the bicycle'.

Pay attention to the case with the preposition 'auf': you ride 'auf dem Radweg' (on the bike path; dative, location), but you turn 'auf den Radweg' (onto the bike path; accusative, direction).

'der Radweg' and 'der Gehweg' are both part of the street area and are often located next to the roadway. But the difference is important: a 'Radweg' is intended for bicycles, while a 'Gehweg' is for pedestrians. Learners may confuse the words because both paths can be next to the road and look similar. Pay attention to the first part of the word: 'Rad' points to a bicycle, and 'Geh' to walking.
