The main thing is to start, simple enough. You could get a used bike and later move up to what you prefer. I started with a 20+ year old mtn bike, get something that is the correct size and decent quality. A helmet is a must then just ride. My 1st ride was only a few miles and it nearly killed me (over weight and out of shape) the rides got longer and easier. You need to find the type of riding you like and get a bike and gear that meet that need. Check out the shops and ask questions. Good Luck
