Hi,
FWIW I'll ride my folder up to ~ 15 miles in normal clothing.*
My "road" bike 15 to 35 miles some cycling clothing.
I never do less than 15 miles on the "road" bike.
But then again I don't go out to hammer 10 miles,
rgds, sreten.
* I've done more, but saddle issues at around twenty
miiles, and you really can't ride a folder in cycling kit.
