I am a grown adult who does not know how to ride a bike and am DETERMINED to learn. I did learn as a child but seem to have forgotten (proving the old adage wrong). I welcome all tips on how to survive while cycling. I am generally okay when there is an open expanse in front of me, but as soon as I see another human/car/biker it all goes to shit. I plan on taking out my new (used) bike every evening to practice but would love some practical advice for getting over my nerves.
