I can, especially as a one man band photographer filmmaker/videographer who always works solo.
I currently use 2x photo dedicated cameras, 2x video, 1x monopod, 2x tripods, 2x lightstands, 2x lights, up to 6 pieces of audio gear, 1x drone, multiple camera angles at the same time, photo and video at the same time...
There are parts of every job where I use every single one of the above at the same time except 2x photo cameras.
I can have 3 video units rolling, with an audio feed to each, shooting stills with the drone up shooting video straight down statically.
OK, with the drone, it's a frikkin nightmare doing that and last time out I crashed it into a tree landing it 200 metres away...but it can be done.
And that's with single attempt no second chance scenarios.
Now carry all that on a bike plus all the other gear?
Obviously not, but a single robust dedicated camera and either 1 or 2 max lenses, carbon travel tripod, super-lightweight collapsible lightstand and small LED plus audio gear takes up near zero space and battery life is excellent. Tiny compliant drone.
Yes, I can see one person handling this just fine, especially if you are taking your time.
I think all of us to a degree can overthink these things and volume of kit creeps up.
I'm on a reduction mission myself right now in this regard having allowed my own volume of gear to creep up.
I had a kit rationale recently and asked myself, "do you really need 6 lights and when have you ever used 6?" Err, never.
Do I really need that 3rd camera angle for video or is it just overkill and one more thing that actually risks screwing the entire scenario up because you are now juggling too many pieces of kit that all need to be focused, or not focused and rely on AF and is the transmitter for the audio switched on and is the receiver also and...
Sometimes, often even, less can end up being more.
