So we were rolling down the rover path in Taipei when we came upon a Birdy bicycle at a rest stop. Half the bikes out there were mini-wheeled folders, but this one had tiny HED aero wheels on it.
On a recumbent traveling at 30mph+, the aero advantage would be inarguable. On a sunny bike trail at 14mph, they are probably more fashion than function. Mind you, I’d love to wind it out to see if there’s a difference at business speed on a mini velo, but that bike trail was just too crowded for riding tempo…let alone sprinting.
