Electric bicycles are being offered for hire in the Cairngorms National Park.
The park authority said the idea was to allow people to explore the area in a more environmentally-friendly way.
A network of free charge points has been put in place and the electric bikes are available to hire from a number of sites.
Helping to launch the initiative was 75-year-old endurance cyclist Penny Weir, from Aviemore, who has completed a number of long distance rides.
In 2008, with Mavis Paterson, from Dumfries and Galloway, she completed a 6,000-mile charity cycling marathon across Canada.
