I was wondering if anyone here has ran a Nexus 3 coaster brake hub on a 20" kids bike. Experiences and thoughts about this would be appreciated. My Mother and myself are planning to purchase a 20" wheeled bicycle for my Niece (Moms granddaughter) for Christmas and I would like to add a Nexus 3 hub to it. I'm hoping we can find a vintage American made bike for her instead of having to buy a new China bike. Been looking but haven't come up with a good candidate yet. It has to me mostly pink or purple and in very good to excellent condition for her. I had considered buying a girls frame, painting it, and building a bike for her but my remission period is fading for this year and I will likely be to ill in the near future to tackle such a project. Lacing a Nexus hub will be enough of a challenge since I've never laced a wheel before. Think I can do it because of all the good posts about it here and videos on YouTube.
