Winter Bike?

I have been thinking about my ‘winter bike’ idea, and I realize the bike I bought is trying to be too much.  It can’t have it be a fixie and a mountain bike and a winter commuter.  However, it is possible to salvage the bike.  I could put a big chain ring on it.  Right now the gearing is miserable.  I detest the handlebars, too.  Maybe they can be adjusted.

My other altertative is to sell this bike and buy an old junker track bike, put some cross tires on, and go fixie.  This is the attractive idea, at the moment.
