Colin Furze made “Mad Max Stroller” — a carriage with a 125-cubic-centimeter motorbike engine that cost $750 in parts and took four weeks to build. Furze isn’t stupid enough to actually put his child in the Mad Max Stroller and speed around town at 53 miles per hour. Although he does have a doll wrapped up in a blanket to fool people, the baby carriage is purely for show and another notch for his collection of Guinness World Records. Furze even admits that the handlebar accelerator, brakes and ruggedized wheels from an old mobility scooter are a little unstable for daily commuting.
