I'm a novice not sure where to get a bike education? Like most kids I road everywhere through high school than my biking waned to the neighborhood rides with my kids when they came along.  Currently I have a Schwinn Single Speed Cruiser that my dad special ordered for my mom from a Schwinn shop in the late 80's/early 90's. She didn't ride it much and I've had it about 18 years and my hubby has kept it maintained for me. I have no knowledge of bike vocab/lingo but want to extend my biking skills and ride more trails.  I don't know where to start, don't know if I have the best bike although at this point it's what I can afford.  Advice?
I would inquire at your local bike shop or look on the internet for a local bike advocacy group in your area.  These are generally a fantastic resource. 
Some of the education my local group offers are below, additionally they also have regular rides, both adult and family oriented. I have heard of other groups offering comparable resources all over the US and Canada. If you happen to be in the US, The League of American Bicyclists has a search tool to find local groups.
