Perhaps the worst bike ever made; I don't say this casually, I've worked on them and ridden them. There were a lot of them in my area because they came free with purchase of a stereo or TV. Bike shop Yellow Page ads frequently had the phrase "We will not service Firenzes" (really!)

Anyway, no matter how easy it is to put on a new bb and crank, it'll always be a pig. I understand not wanting to spend a lot of money on a bike when you're not yet a cyclist... but this will not be a good introduction.

We frequently get guys like you in here who buy the bike first and then come looking for advice. That's too bad because we have a lot of good advice for what kind of bike to buy.

So... I would advise against spending any more money on a new crank and BB, but if you can find another old bike with an English BB you might enjoy getting your hands dirty with a swap.
