Are fixed gear bicycles best for cadence training?

[alex c]

As an avid bicyclist and runner for many years, I recently got a fixed gear bike together from a few bikes that were laying around. The bicycling lifestyle looks really appealing to me more than ever and I want to save up for a decent, lightweight road bike with all the bells and whistles.I haven't biked for a few months now and I am wondering if you think fixed gear bikes are good for cadence. This being my first fixed gear bike, I found it fascinating that I have to pedal constantly or fall off. I just came from a 40 mile round trip and my legs feel awesome. I run a 40x16 ratio for now and surprisingly I am really fast on this gear. I feel this ratio is best for hills and that I can go faster but I have this ratio for now willing to work my way up to 14 then eventually 11 in the back. I have the logic in my head that it does do wonders for your cadence but something tells me to ask someone that would know. Thank you all in advance!
