Eliminating the driven sprocket
- Thread starter Pablo
- Start date
The leetle fat tube at the very bottom of your frame where your crank goes through.
yes bottom bracket is in inside the round part at the bottom of the bicycle the cranks screw to. they can cost alot for a top of the line one
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.....................
Is this what your talking about??
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.

I'm going to remove those tubes from the seat post up to the neck and weld in a bar so it will be a boys bike when I'm through. I bet I'll have lots of room if I do that. The main reason I asked was because the frame I was originally planning on using was a boy bike but it has the larger pedal bearings. I just want to make sure the freewheel crank will fit the frame....................
Please explain - you mean everything less the "crankshaft, cranks, nuts, etc"? - perhaps. We would need to price it appropriately.
I think I understand - you have a freewheel....but does it have two chainrings? (large one to be driven by the small jackshaft sprocket, other smaller chainring for driving your normal bike chain)
This is a phenomenal invention guys. I am STOKED. More so because you are here in WA state! I am coming to you. Don't go anywhere I'll be there in an hour..
