New (to me) bike- needs help!
I have recently purchased a 27" Free Spirit Sun Bird road bicycle and am fairly happy with it thus far, however, I do realize it needs some general maintenance. Also, I am hoping that the noises I am hearing and the minor problems I have been experiencing is not something I need to be largely concerned about. I apologize that I am unfamiliar with all of the terminology of the parts of a bike (although I do know quite a bit because I have been riding and servicing my personal bicycles for about 10+ years and have been learning along the way).
I believe there may be a problem with the rear cassette and whatever slips when I am coasting. I think there is a problem because I was coasting and went to pedal again, normally it would catch and start powering me forward, no problem. However, I found today that the pedals moved forward and spun around about 3 times before the drive mechanism caught and started moving forward again. It did that a couple of times and then seemed to resolve itself. I wonder if the slip mechanism in the rear wheel is failing or needs to be lubricated, etc.
Also, I notice grinding noises from what I believe is the crankcase as I am pedaling, primarily going up hills (under heavy strain, etc). I am wondering if the crankcase is failing, needs to be lubricated, or it is something in the rear drive mechanism.
