My since of ridiculous is probably different than other people’s, but here are some bikes I would not want to ride 750+ miles on, in a row.
tandem made from 2 inexpensive department store mountain bikes.
90%+ of the bikes were off the rack road racing bikes, with skinny tires, no real lights, or mudguards.
Sure this is a nice Colnago, but the rack is made of metal, sticks, and tape. really, there is branches from a tree. plus no toeclips.fairly aggressive gearing. She finished, but past the cutoff.
