Take a Deep Breath and Say AHHHHH!
hey Lee,
Welcome to TE.Kudos to you for getting a new bike.First off,just relax and enjoy the sensation of moving your body as you haven't since you were a kid!There is no greater feeling than the freedom a bike imparts to your body and your spirit.Like the other ladies said,find an empty parking lot or a park with some grassy areas that you can practice on.Take your time and work the middle chainring until you feel confident in knowing what gear your rear cassette(back gears) are in and what combination works for you.Definitely spin easier gears so that you don't put any stress on your knees.In a couple of weeks,you'll get the hang of it and find gear combos that work best for you.If you have a real local bike shop in your area you may check with them to see if there are any bike clubs in your area that offer tips and rides for new riders.It's a great way to meet other cyclists and up your learning curve quickly.Most cyclists are a friendly,helpful bunch and alway happy to welcome someone new to the sport.Again,congrats to you and welcome to TE!
