I like it!
I was playing around a bit.
That is the Bikingreen 70T chainring. They're not too expensive on E-Bay.
Unfortunately the front derailleurs don't like them.
That has a Sachs Dual Drive hub behind it which pretty much negates the benefit of the 70T. I can still climb pretty well in the 70T.
Keep in mind that a 20" wheel has about 2/3 the gearing of a 27" wheel.
