The bearings are shot on the freewheel for my mini4 and so I'd like to replace it. Rad wants $40+ plus shipping for a new one which seems awfully high to me.

I'm guessing that this is a standard item used for other kinds of bikes but I don't know what to even search for or what to ask. Can anyone give me any advice on what to search for, or the model or size?  Are there any good sources for these?

Thanks for any help that you can give.

My wife and I both have Mini4's that we really like. My bike, however, occasionally has a mind of its own that I'd like to tame.

If I walk beside it with the bike turned on, the pedals go round which fools the bike into thinking it's being ridden. When this happens the pedal assist kicks in and the bike wants to take off on you. This was quite a surprise the first time it happened and luckily I had a firm hold on it and got it stopped. My wife's bike doesn't do this (thank goodness).

Can anyone give me a hint how to stop this?  Obviously the crank should not revolve while the bike is just being pushed, but I don't have any idea what to adjust to stop it.

Thanks for any advice you can offer.
