Rules covering taking bikes on trains are laid out at National Rail and A to B Magazine.
The following ferries carry bikes for free:
Ferry services between Gourock and Dunoon, Wemyss Bay and Rothesay, Largs and Cumbrae, Ardrossan and Brodick, and other west coast destinations are shown on the Caledonian MacBrayne website.
Times of buses to and from Wheelcraft at Clachan of Campsie are found in these timetables (these services do not convey cycles, but are useful for getting to and from Wheelcraft to collect wheels). Wheelcraft is located adjacent to the bus terminus.
Scottish Citylink will only accept folding bikes in an approved bag. Bags can be purchased from Citylink at the counter in Buchanan Bus Station.
Stagecoach carries bikes in the boot of its coach-operated express routes, including services between Glasgow, Ayrshire and Fife. Bikes are normally loaded at bus stations rather than roadside stops. Timetables are also at Traveline.
For details of other bus services in Scotland that convey cycles see Traveline.
The Cyclists' Touring Club produces a leaflet entitled Taking a cycle by bus and coach in Britain.
For information on all bus services in the Glasgow area try the Glasgow Bus Timetable Finder.
For advice on interaction between bikes and buses on the road, and road safety, see this leaflet from Oxford (619kB).
