We recently had this leaflet through our door. It offers the opportunity to "discover public transport", by giving each member of the family a one day pass to the local bus network.
The leaflet also points out that folding bikes are allowed on the buses for free as hand luggage.
Being able to take a bike on the bus is a very useful option. I prefer to cycle, but I've done this three times already this year to get to Groningen for work when it's raining too much for the 60 km round trip by bike.
