Basics

This page aims to determine the towing capacity produced by the average person on an average bike
May add other categories later
Mainly used to determine the reasonable capacity of a non-dedicated cargo bike setup (ie a trailer etc)
According to this 15km/hr seems like a reasonable "cruising speed" with a bit of variation
May want real world data
From Wikipedia:
- "Cargo tricycles can typically carry 100–300 kilograms" (also said human endurance/power is the main limit) (and 50 kg for bikes with basket only)
From the quora answer:
- "Our experience has been that most people can comfortably pull 300 lbs (137 kg) with a typical mountain bike and cargo trailer or cargo trike. How quickly a person can move load of that weight will depend on his or her physical condition. Someone in reasonable physical condition can generally pull a 300 lb load at 10 mph (16 km/hr) on level ground if there's no wind. A person exerting the same effort could pull a load of 600 lb. (275 kg) at a speed of about 8 mph (11-13 km/hr), and a 1000 lb load at about 6 mph."
Guestimating 250kg at ~10km/hr?
