Eliminating the driven sprocket

I'm not a biker, but what is a bottom bracket?

The leetle fat tube at the very bottom of your frame where your crank goes through.

So Pablo, will your crank fit the bicycle I have in the photo? The other frame I was going to use has the one piece crank. I actually think this frame will be less work than the one I originally was going to use. I just want to make sure whichever one I use will work with the jackshaft.....................

It looks like that one will work with the kit. A bit rusty, and funky.

It's been laying in the junkpile for a few years. I'll have to unrusty and unfunk it................

OK I put the 10 tooth gear on and rode like a maniac - balls to wall on pavement and chuckholed gravel roads - man it's spring - I got bugs on my teeth. I beat it hard, so hard that I scared myself enough to stop and check everything over. Nothing loose.

OK if the production sample gears show on Monday and they fit and work - we will start spending our $1000's of dollars to get production rolling. Can you say "VISA and Mastercard"?

Pablo, weren't you supposed to be at your daughter ball game?

I don't know if Ilikeabikea's frame will hold a engine. Those extra tubes might get in the way.

Just for some clarification on the bottom bracket. You need what I think is called "cup and cone" style. Attached is a photo of the type of spindle that your current bike should have. If you have the newer style I am told that it can be retrofitted back to the old style.
