A £3.9m project aiming to get Scots on their bikes was unveiled in Fife on Friday.

The Scottish Government wants 10% of all journeys to be made using pedal power by 2020, with the funding package set to support the creation of new cycle paths, a traffic free route through Glasgow city centre and more cycle training for children.

However, the move has sparked criticism, with environmental campaigners saying the cash is not enough to reach the target while the Conservatives argue the £3.9 package is “unaffordable”.

Speaking as he unveiled a new stretch of cycle network between Kincardine and Culross on Friday, Transport Minister Stewart Stevenson said: "As a result of our cycling plan almost £4 million will go into building new cycle routes and improving cycle training.

"I am confident that as we improve the delivery of cycle training in our schools and construct new cycle routes, like the one I've opened today in Fife, that we will achieve our 2020 vision."

According to a recent household survey, just 1% of journeys in Scotland are made by bike while half of all journeys under two miles are made by car. The Government says those journeys could be switched to bike with investment and advice.

Colin Howden, director of transport alliance Transform Scotland, said: "The one-off funding package announced today is welcome but it only represents a drop in the ocean compared to the level of investment required.

"We need to see a major boost in investment in walking and cycling when the Scottish Government publishes its spending review later this year.

"If this doesn't happen then we can't see how the Government can meet its aspiration that 10% of all journeys be made by bike by 2020.

Tory transport spokesman Jackson Carlaw said the funds take the total budget to an "unaffordable" £17 million.

He added: "No one is denying cycling is an excellent alternative mode of transport. It's healthy and is a great way of cutting carbon emissions.

"But we can extol the virtues of cycling and make it easier for people to cycle without spending £17 million. The fact is that, thanks to Labour's legacy of debt, we are living in difficult economic times and every penny of taxpayers' money has to be justified.

"In the best of circumstances this funding is a luxury. Right now it is unaffordable."

Liberal Democrat transport spokeswoman Alison McInnes said: "It is unfortunate that the SNP have not used this opportunity to produce a genuine step-change which could have revitalised cycling in Scotland.

"Cycling can benefit people in lots of great ways. Not only does it promote a healthier lifestyle but also has far-reaching benefits for the environment which makes the Government's action plan all the more disappointing."
