Too many hills and thus selling it? Hilly riding means you need to change the bike from your Corvallis frame of mind. Put lower gearing on it and continue riding fixed in your hillier area. British bike riders rode fixed on rides including hills. If a certain one or two hills are too steep for your lowered gearing, then walk up those hills and ride all the others. Try 60 gear inches. I ride my 1944 Claud Butler Continental Club in a hilly coastal area with 46/20 (60 gear inches). You may wish to consider putting brakes on it for your convenience to ride a hillier area. I use front and rear brakes to control my Claud Butler easily on long steep downhills. It's not just me riding single gear in hilly areas. I ride occasionally with some younger guys who ride single speeds at 60-68 gear inches and they jam up the hills okay.
