The co-op got their order in and my hub was among the schwag. I brought it home with me just so that I could show my daughter. She will be excited and this is the missing piece of the puzzle. Now, with the assistance of the fellows at the co-op I can begin to build the wheel.
I am glad I went with the coaster brake. For a ten year old (my daughter) I think that this will be a more solid and reliable stopping option.
It is heavy, probably 5 lbs., but it's a cassette, derailer and brakes all in one little, slick package.
