James May and Oz Clarke hopped onto an electric-powered motorbike made of Meccano to complete a lap of the Isle of Man's famous TT circuit.
The challenge was for the Christmas special of James May's Toy Stories.
"After having seen James take on the challenge of building a Meccano bridge over the Liverpool canal, it came as no surprise that he wanted to do something even more technically challenging for his Christmas special," said Sue Barratt, country manager at Meccano Toys (UK) Ltd.
"We have been working closely with his team to pull together the parts to enable the bike to be built. It was quite a task - there’s 600 nuts and bolts in each wheel alone.
"It has all been rather hush hush so we're delighted to learn that he managed to complete a lap of the world-famous TT course - even if living up to his nickname of Mr Slow!"
The bike was created over nine weeks by Toy Stories and Man Lab’s project manager, inventor and engineer Simeon Oakley.
