Hello all, first post here.

Im getting back on a bicycle after about 6 years of not riding one (last riding was on a mountain bike, grew up riding BMX). Also, I live in San Francisco and haven't done much urban riding (I had my mountain bike down here, but mostly rode it around my college campus, never went into the city with it).

My end goal is to ride fixed, however my bike will have a flip-flop hub with a freewheel side... so my question to everyone is;

Should I start off with the bike in a fixed gear configuration and just get right into the learning curve of that style of riding, OR, should I start off with the freewheel option to get comfortable on the bike in general, given my time away and the new riding environment?

The idea of going freewheel for a while to ease into urban riding is appealing and seems like a gentle way of going about it, but I wonder if it'll hamper my learning to ride fixed down the road (which is what I really want to do).

Thoughts, opinions, experience, and of course sarcasm, are welcome.

Thanks in advance.
