Text: Amazon’s electric cargo bikes have arrived in DC.
Image: A four-wheeled vehicle that appears to be a cross between a bicycle, a go-cart, and a mini-truck
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:
Bicycle can also be 3 wheeler, either 2 in front or back like adaptive bicycles
or even 3 in line like this
There’s also 4wheel adaptive bicycles like this one
Noteworthy also that only 2 from the above had a handlebar!
Now I’m not defending loopholecyle, which is basically a light truck, but just pointing out that your definition is very wrong
The words are tricycle and quadcycle
Bi means two
A trike is not a bike
Behold! A child riding a quadcycle!
Yeah that’s the origin of the word
Just like one would think of the dice game when talking about ‘hazard’
Sometimes words change their meanings
I’m not usually a linguistic purist but we can’t let two mean three.
I would call the first image a tricycle (The shoulder-driven steering linkage on that thing is cool as hell btw), the second one is a concept that the builder does admittedly call a bike, and the third one a quadcycle with a pedal assist motor.
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.
