Apparently needs trailer brakes...
“..the entire loadwaste, trailer, bike, Ibarraadds up to almost eight hundred pounds.”
They’re talking the load of man, bike, trailer and waste weighing 800#, not just the load. That waste food is probably damp and packed into that container.
Since all that does have to be stopped I can see adding it all up. Still doubt the 800# figure though.
Riding that bike with hand brakes down a hill with 800 pounds on a tiny trailer behind it is a job for the guys from Jackass.
Not hard to believe if Ibarra weighs 400#s.
That does seem like a lot. Probably beyond the capacity specs for the trailer. The wheels and axle in your picture don't look like they could hold that much.
Possibly they're talking about "government contractor pounds," which are what they've been billing the city for collecting and hauling. These do not necessarily bear any relation to what you and I call "pounds."
