Mi padre monta en bicicleta todos los domingos is translated to my father rides a bicycle every sunday. They used the "va a" because of the "goes", so it's not the future but rather a simple translation of "to go". Here you have a repetition of the action (todos los domingos), it not an immediate future like "next sunday". For example a future would be something like "my father is going to bike next sunday", and the translation would be "mi padre va a montar en bicicleta el próximo domingo". I hope that helps.
