WLB - The World's Longest Bicycle

Em and Bill are twelve-year-old twins. After their mum and dad die, they live with their wonderful grandparents, Pops and Grannie. Together, they invent an amazing, snake-like bicycle that can seat up to a hundred children - and it even has ten superseats for those who can't ride by themselves. The amazing bicycle is able to bend round corners and can even wind up and down the aisles of a supermarket. Everyone wants to know about it and it becomes a world-famous super-bicycle when they ride round Monaco in front of the world's TV cameras.
