I'm certainly not a pro at biking or maintenance or anything like that. I've owned a Schwinn Rocket 2 mountain bike for a year. In the last year I've fallen in love with the idea of a folding bike and after much research, I bought an orange 2005 FS Downtube on Ebay. I've had it less than a week, and already love it. I've been reading through the posts in this forum for the last few weeks and have a few questions.

Many have talked about replacing the "BB" in their bike. Can someone tell me what that is? I know a little about bikes, but I guess not as much as I thought.

Also, are there other folder owners who have had problems specific to these bikes that they've found solutions to that would help a newbie like me to know what to expect?

I'm sure I will have many silly questions in the future, and appreciate any helps anyone offers.

Thank you!
