For space efficiency, yes. Bikes are actually better than walking for CO2 output. Your food has a CO2 cost, and bikes are really damn efficient at turning your food calories into forward momentum. Ebikes are even better on a per mile basis, but their higher manufacturing cost mean they never catch up to lifetime CO2 output of a regular bike. Still, whatever gets more people on bikes is a win in my book, ebike or otherwise.
Yes, it's the new scheme work put in for reducing hamster ball costs, ballsharing. I mean, most people run in hamster balls with more space than needed, no? Although it would more efficient if there was a bus route to carry all 50 people ngl.
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
Realistically, the 50 people riding a bus scenario will become 50 people riding a bus with rest of the road space occupied by 16-wheelers or other large transportation trucks
