...wonder how fast a 50-seater tandem bicycle could get going, assuming ideal conditions and riders.

At least 12

How fast can it stop? I wouldn't want to first heading against a crossing or wall with 49 people pushing the pedals behind me.

Chatgpt says

Professional Cyclists: Elite professional cyclists can produce power outputs of 300 to 400 watts during races, with peak efforts exceeding 1,000 watts for short bursts (like sprinting).

Time Trials and Climbs: During time trials or climbs, trained cyclists can maintain higher power outputs for extended periods, often around 350 to 450 watts for well-trained athletes.

But then it tells me 40km/h assuming 400W which is obviously wrong. I guess you'd have to model that "tandem" in CAD and simulate the airflow to get accurate drag numbers

If I wanted to ask ChatGPT, I would ask ChatGPT myself. You're useless.

Could've done without the insult.
