The Rush will provide bike hire, trail information, guiding plus food and refreshments at a new cycling complex in Dykecroft visitor centre, Newcastleton.
The joint venture is part of the European-funded 7stanes project which aims to create seven mountain bike centres right across the south of Scotland.
Jeremy Thompson at Forestry Commission Scotland said:
"We are really excited at The Rush coming on board with us to take forward this venture at Newcastleton. In the Borders we've always wanted our mountain bike projects to be run by mountain bikers as this produces a great
"We now have three new businesses starting up as a direct result of our mountain bike developments and this is great news for local employment and the economy. With top notch facilities attracting more visitors we can
really put our stamp on the tourism market."
The Rush is the latest mountain bike business to start up in the Borders following the tyre-tracks of the Hub cafe and shop at Glentress and the downhill mountain bike business Progravity at Innerleithen.
The 7stanes project is being carried out by a partnership of Forestry Commission Scotland, Scottish Enterprise Dumfries & Galloway, the European Regional Development Fund through the South of Scotland European
Partnership, Dumfries & Galloway and Scottish Borders Councils and Tourist Boards, the Heritage Lottery Fund, Scottish Natural Heritage, Solway Heritage, Barony College and local cycling volunteers.
