The World’s Tallest Rideable Bicycle Is Over 25 Feet Tall

Two French biking enthusiasts recently set a new Guinness World Record for the ‘tallest rideable bicycle’ by building a 7.77-meter (25 ft 5 in) behemoth that can (barely) be ridden.

Nicolas Barrioz and David Peyrou came up with the idea for the world’s tallest bicycle 5 years ago, while drinking at a pub, but they actually decided to go through with the project and spent months putting together a plan to make it work. Made from metal alloy, steel, and wood, the unique bike took hundreds of hours to complete in a way that made it rideable, even for a short distance. It may not seem like a challenge, but building a 25-foot rideable bicycle is definitely not as easy as riding a bike. For example, the pedals are connected to the wheels via a 16-meter (53-ft) chain, and because of its extreme height, the bicycle has to move at a speed of around 15-20 km/h (9-12 mph) for the rider to maintain balance.
