Two teams go head to head in a challenge to transform a pile of scrap metal and old bike parts into awe-inspiring cargo bikes. Oliver Bridgewood & Paul Burford take on Mildred Locke & Ted James to construct new bikes from old, all under the watchful eye of judges; Manon Lloyd and Andrew Denham. After three days building in the workshop, their creations will be put to the ultimate test in a series of challenges. Will their designs be able to take the load? Who will be crowned the champion of GCN’s Junk Bike Battle?
