The scheme, introduced in summer 2021, allows passengers to use a supplied "bike sock" to cover their wheels and chain so that the bike can be carried in the luggage compartment without damaging other baggage.
The pilot service has been run as a partnership between Scottish Citylink and Stagecoach and funded by HiTrans, the regional transport partnership for the Highlands and Islands.
It has been operating on Stagecoach services between Inverness and Caithness, and Inverness and Ullapool, and by Scottish Citylink on services between Inverness and Skye, Fort William and Ullapool.
Data gathered during the pilot shows that the Ullapool to Inverness route was the most popular for bike carriage, mainly due to people returning from completing the Hebridean Way cycle route, which goes from Barra to the Butt of Lewis in the Outer Hebrides.
