NICE bike Ann-Marie!!!! i luv vintage single speed step through frames.....and those are also very hipster-ish where i live
don't do much to it (the bendix hub won't allow a change to a different sized sprocket) just ENJOY riding and getting even healthier!!!!!!!!!..if you find you're having a problem just ask as there are some very knowledgable women here. It's a learning journey, enjoy being on it...
....and welcome to TE
