    For help "Right NOW!":

    1. Say what you need help with in the subject line so people will read
    it

    2. Use the search function "Right NOW!" There have been many threads on
    this. People already did the writing. Now you just need to do the
    finding. Hints: You need a cotterless crank puller tool -- Your crank
    type is cotterless.

    That's a fair question. Usually cotterless cranks come loose when you
    don't want them to, but hold like they're welded when you do.

    But often you can get them to loosen up by riding around with the
    nuts/bolts off. Hop a little with one foot in front, then a little with
    the other foot in front. Or just idle for a few minutes with each foot
    down. Eventually you should feel the crank moving around.

    Don't overdo it; this will cause wear and tear to the parts.

    Even if you do manage to get the cranks off without a crank puller you
    will still have to deal with getting the bearings off without a bearing
    puller. That's going to be the hard part. If the bearings are tight on
    the hub (which the should be) you are not going to be able to slide them
    off by hand. It requires something like 'this'
    (http://www.unicycle.com/shopping/shopexd.asp?id=419) to pull the
    bearings off a standard hub.
