I am about to embark on my next 700c childrens bike.  After building on with my oldest son we found out it fit my daughter as well.  So now she is very excited to start hers.  I really liked how it turned out, not much I would improve on for her so it should be an easy build.   This could be a trend, but it might be hard to keep up with these kids that seem to keep growing. Especially since there are 5 of them.

Just a reminder, here is his bike:  https://everydayracer.com/2015/09/01/the-boys-road-bike/
