Response text from high t alpha shemale @gluetaster: that’s not a cargo bike man that’s a loopholemobile
Edit: I found a slightly higher-quality version of the image:
Trikes and quads might share characteristics with bicycles, but they’re not bicycles because they don’t have two wheels.
“a vehicle with two wheels tandem”
“a two-wheeled vehicle that you sit on”
“a vehicle with two wheels in tandem”
“Bicycle is a two-wheeled vehicle powered by the rider”
“bicycle, two-wheeled steerable machine that is pedaled by the rider’s feet”
“a bicycle, a bike: a two-wheeled vehicle moved by pressing down on pedals with your feet”
Sometimes you could argue that there’s a grey area between a moped and a bicycle, or an e-bike and a bicycle. But, the two wheels is a key part of the definition. As soon as it’s more (or less) than two permanently attached wheels, it’s no longer a bicycle. That’s why we have words like unicycle, tricycle, etc.
