During the summer season, PostBuses are fitted with rear bike racks (minibuses excluded). These can carry up to 5 mountain bikes. Riders must travel on the same bus and load their own bikes. A valid ticket is required for each bike. There is no guarantee that there will be sufficient room on any given PostBus. If a vehicle is already carrying the maximum number of bikes, any additional riders wishing to board with their bikes will be carried on the next PostBus.
