You ll know of the old original ones with "fans"

l was interested to hear anything said about these ergo vs regular indoor cycles (heavy fly wheel fixed with rubberstopper for resistance)
Whether anybody swears by them?

l may have the opportunity to get an old roadbike frame and get it "converted",its cheaper than "spin bike" and l dont want to stress biannchi frame on trainer either.
Admittitly lm not sure if they fixed or not.
