No, I don't see  How To Post Pictures
Toward the end of this thread the members really helped me learn how to post pic's http://motorbicycling.com/f28/post-m...tures-916.html
To use attachment:
When posting scroll down to "Additional Options"
Click on "Manage Attachements"
A window will open up
Upload a pic from your computer by clicking "Browse" then click "Upload"
Or enter the URL and then click "upload"
If you did this, and your pic's did not come out....they are most likely over sized and you must make them smaller.  |

I don't know if that would work and I thought of that also. I guess that I need to see a breakdown and operation of that drive hub, will have to do some reasearch on it.
The hub is only 250 watt 24volt and runs about 14mph, would like to have a little more speed and range.

In all honestly I still think Pablo's kit would be the cleanest solution. Not cheap, but clean and would work well. Then you don't need to install a new sprocket on the rear wheel, it just uses your existing pedal/chain/gears setup. Eliminating the driven sprocket |

HI,
Looks like a big hub....What material is it made of?....I wonder if some "studs" for a 9 hole mount sprocket could be welded to it then simply use washers to space out a sprocket and bolt it directly to the large hub....
Just a thought,,,,Good luck!
