After doing some thinking post-this thread I have decided that I want to swap out the rear coaster brake hub on my son's bike (Islabike CNOC 14) for a freewheel hub. I've read various posts on converting a coaster brake hub to a 'freecoaster' hub but I'm not convinced that's going to be the choice for my son. The 1/4-1/2 turn to get pedal engagement seems far too clumsy but I could possibly be convinced, especially if the freewheel hub conversion turns into a true pain.

I am hoping I can find a cheap freewheel hub that can be a direct swap for the current hub, although worst case I'll just buy new spokes, too. The current hub dimensions are:

110mm OLD
16 holes (likely going to buy a 32 or 48 hole hub and just skip holes)
47.5mm center to center of the flanges (need to measure offset, if any)
diameter 51mm centerline of spoke holes

Any thoughts on a suitable replacement for this hub? Barring a direct swap, which hubs would be a good candidate for this conversion? Most hubs I'm finding have fairly wide spaced flanges which I'd like to avoid given the tiny wheels on this bike (14" wheels which measure slightly over 12" over the 1.5" tires). The spokes already enter the rim at a decent angle so any wider or taller on the flanges will only make the issue worse. If I can remove spacers from a wider OLD hub to make it work that'll do, too.

Thanks for the help!
