I'd like to do the yellow band Schwinn model, just not sure about buying something like that on-line, condition could be anything and they run $100+.

Any thoughts or experience with these new ones from Amazon? It appears this is a very niche market.

This one comes with the whole wheel ready to go.

This Sturmey Archer one doesn't have a very good rating but I like that it uses the standard rear cog, where I can play with different ratios to find one that fits my riding style.
