Hi - I am looking for a bike that won't break as much as my cyclocross triple monster. So I want a freewheel single speed. Simple. However I have knee problems so I can't mash the pedals, so I need some kind of smaller gear on there to save my knees. Is there such a thing as a three-speed?
EDIT: A decent, new-type bike though. Not a vintage.
Thank you sirs.
