One way to gain skills and confidence is to ride with more experienced riders. You watch them and do what they do (if and when you are comfortable doing so).

Try to find someone with experience to ride with, but who will ride your pace and only go in easy to ride areas. Someone who will allow you to ride at your comfort level where there's low traffic, the least amount of signals, etc.

Is there a club in your area? Ours has a women's only ride on Sundays where the pace is easy and so is the route. That sort of ride would be perfect for you.

The more you ride, the more comfortable you'll get.
