This is the Official Longest Bike (For Now) in the World
The official longest bike in the world is about 35m long (117 feet), which is almost half a block of a huge office building.
The 2 bikers' seats are linked with aluminium trusses. It's apparently very easy to ride, but really heavy too, and it can't turn corners.
