For those of us who live in really hilly areas but want the weight of a fixed or single gear bike has anyone heard of building a single rear cog with a double crankset/front derailleur bike? I am sorry if this has already been addressed but I could not find it in the search feature.
I am a newbie here and to the idea of fixed or single gear bikes. I guess it l must be regressing to the times I learned to ride a bike, single with a coaster brake but after riding only multi speed bikes I would like to give the single rear cog a try but in the hilly area I live, I would be walking the bike uphill all day long.
In short anyone build a single rear cog bike with a double or triple crankset?
