The rebel is a great first bike. It's easy to handle, and won't overpower you.

Check the motorcycle safety foundation for rider's courses, most of the time there's a local chapter that has riding lessons for a small fee, they supply the bikes, all you normally need is a helmet and your learner's permit/license. The MSF courses normally also help you with the riding test for your license. If you have no experience on motorcycles, these courses are an excellent starting point.

Make sure you wear a helmet. It may be more comfortable to ride without one, but the first time you get a rock or other road debris kicked up into your face you'll be glad you had the brainbucket on.
