    How to find me1003 hub, can you help?

    I am struggling to find a correct hub to suit a me1003 motor.
    Just to be clear because I am not 100% that I am using the correct terminology for what I am looking for: I want a female to fit the the motors rotating out put which will have a sprocket attached.
    I have seen a few with the right inner diameter on eBay but never the right keyway, is it possible to key a key which fits one size on the outside and one on the inside?

    Also if there is a device which I could plug into the wall which would simulate a battery pack so I could test before my batteries are bought that would be pretty sweet as well (but this is less important.).
    Thanks in advance!

    Stupid Yankee measurements.

    22.23mm round with an 4.78mm keyway

    7/8 inch bore and 3/16 inch keyway

    example if you are in the states http://www.mcmaster.com/#roller-chain-sprockets/=yog1yj

    OMG sooo helpful.
    Thanks ken will, the first is exactly what I was asking for when I mentioned a "a key which fits one size on the outside and one on the inside" and then second link is cool as well.
    Thanks a lot tomdb that's another awesome link but I had imagined getting a piece just like that but without the sprocket and then having it drilled and tapped so i could change the sprocket.
    Do you use sprockets / hub units from that site ?
    What do you think of them?

    You could use a power supply, Mastech are decent quality. But you'll need a 100V model and those start at $300.

    Or if you already have a charger picked out you might be able to power the controller with it. Depends on what type of charger.

    Why bother with drilling and so? Search on Ebay for sprocker 7/8 bore and you will find a lot of different sprocket you can use.

    You can take a standard key and remove lite on top so it fits key slot in sprocket. I did so for my sprocket.

    And if you want to test your motor a car battery will work fine.

    I just thought it would be useful to be able to interact with traditional or oem motorcycle parts, but the more I hear of the availability of these sprocket+hub pieces the more i think my original idea may not be worth the hassle.
