NATIONAL Park chiefs have launched a hi-tech attempt to ensure that cyclists exploring the New Forest stick to authorised routes.

Visitors planning to tour the area on two wheels can now hire a cycle with its own computer – described as a sat nav for bikes.

It follows a spate of complaints about riders deviating from official cycle tracks, either accidentally or deliberately.

The National Park Authority (NPA) has teamed up with technology firm Garmin to provide cyclists with GPS navigation devices to help them find their way.

Loaded with easy to follow cycle routes, they are available free of charge with bikes that can be hired at outlets around the Forest.

NPA chairman Oliver Crosthwaite-Eyre said: “We’re always looking for practical ways to help everyone enjoying cycle routes to stay on track.

“People need to know where the permitted routes are and these devices are going to be a great help.

“Cyclists can get the best out of the 130 miles of gravelled tracks while also helping preserve tranquillity and minimising disturbance to wildlife.”

Gail Cook, UK and Ireland Marketing Manager at Garmin International, said: "Garmin is an active lifestyle brand and we are delighted to encourage family cycling throughout the UK.

"I’m very pleased that we’ve been able to support our local New Forest National Park Authority’s cycling scheme with the provision of a large number of our Edge Touring units, a sat nav for your bike.

"These cycling computers are pre-loaded with maps of dedicated cycle paths to encourage family cycling participation whilst preserving the beauty of the New Forest."
