Guy Attempts To Make Roller Blades From Two Kid’s Bikes

This is a video documenting Youtuber Jake Carlini’s quest to build a pair of roller blades using two kid’s bikes. He starts with the version seen above, which proves impractical and basically immobile, even after lowering the bindings and adding training wheels. He then builds a pair with each skate made from two smaller bikes side-by-side, which proves a much more practical solution. ‘Practical’ being entirely relative here, of course.
