I want to ride like the next guy or gal, and will probably ride tomorrow because today and tomorrow is pretty good here on Long Island, NY.
But the long term solution to long winter months is to adapt, and find an activity which is close to riding a bike. Look no further than... SNOWBOARDING. Those who are thinking of trying, but are hesitant, let me tell you something. I've been skiing for many years, and a few years ago got really bored with that. At 50+ years old, I decided to learn how to snowboard. Keep in mind, I am a very slow learner. So, I got a used board and boots on ebay a few years ago. In a few sessions spread over a period of a couple of years, I got to a decent beginner level.
And boy, what a feeling going down the easiest trail, being leaned over almost touching the slope while in turn, completely relaxed and experiencing this perfect balance between the two very familiar forces - gravity and centripetal force. Wait a second! This is the same feeling I get when riding a bike! See what I mean?
Side effects are very similar, too: non-erasable grin on your face, seeing the road... I mean, the slope as you are falling asleep... you know, all the good stuff. Of course, hungry afterwards, and a great topic during dinner.
So, stop doubting yourself, get the board, take the lessons, get past the initial learning curve, and you will be shaking your head and thanking yourself for pushing yourself over that mental barrier, while enjoying very moment of it.
I am not gonna go in details - there is plenty info out there, but just wanted to say this: helmet and wrist protectors are a must.
