My daughter has a Specialized 12" kids bike with a coaster brake that I can't stop myself from re-imagining. It's been a long winter and I've done all the stuff on my bikes I can think of.
Her bike has a 16 spoke rear rim. I have a 32 hole freewheel hub on my bench. I was thinking about relacing the rim on the hub and threading a cog and a lockring on that hub.
Why would I do this? I have heard that fixed gears, like the pedals on tricycles, make a lot more sense to kids and make it much easier for them to learn to ride. Braking is more natural, and I'm also going to add a high end caliper brake with an Avid single digit lever so it'll actually be functional and get her used to hand brakes right away.
It might be kind of nice, though, to not disassemble that existing coaster brake wheel. Anyone know where to get a 12" alloy rim drilled with 16 holes?
