Structure developed in the Netherlands uses steamroller wheels and requires the coordinated effort of five cyclists to move
Unlike conventional bicycles, in which agility and low weight are the metrics of success, the new world record holder bets on colossal dimensions. At 55.4 meters long, the world’s longest bike was developed by a team of engineers from the Netherlands. The structure resembles a monumental steel beam on wheels rather than an ordinary passenger vehicle, but it has secured a place in the Guinness World Records.

To support the weight and extension of the structure, the design uses extremely wide wheels, similar to those of a steamroller. This choice gives the “bike” its own stability, allowing it to balance itself. The operation, however, requires a collective effort, while a single cyclist in the front manages the steering, four other cyclists positioned in the rear are responsible for traction.
In addition, the drivetrain is a mechanical reduction masterpiece; By means of various chains and gears, while the occupants maintain a rotation of 60 rpm, the rear wheel rotates only a few times per minute, overcoming the inertia of the metal mass.
The record is not free from technical controversies. There is debate about whether using five crew members would classify the vehicle as a tandem bicycle, which belongs to a distinct category. Interestingly, the same team holds the record for the longest individual bike, with a similar design of 55 meters, just 20 centimeters less than the collective version.
