"Could I bring it in and have someone let me know if it's worth fixing? Thanks for any help!"
Totally, that's what we're here for. From what you've said so far, it may be better to see if we've got a used wheel for sale and put that on. (Make sure the replacement wheel has a coaster brake if your current one does, or plan to add hand brakes).
Before you get started though, ask a mechanic to go over the whole bike with you, so you can get a sense of what, if anything, else needs to be done to the bike, so you can budget your time and money accordingly.
Perfect, thank you! I'll try stopping by tonight. Thanks again!
