Down a worm hole

Another Anne Oskam bike! The google translation on the site by Johan Vrielink is "
In addition, the legendary developer Anne Oskam as a young man, on the design he made for Batavus , when he was head of the development department there. Again, a different drive than the standard circular movement."

This Link leads to a russian site detailing a Nuvinci style in hub gearbox made by Boris Frolov. It all looks too good to be true, and probably is
one variator costs at 350 Euro, has a pedal range multiplier ranging from 1 to 4, weighs from 2kg and efficiency is not less than 90%!

Hi, I have been on the internet researching bikes and came across a few oddities and some interesting stuff so have put it down here.

Not so much a worm hole this one and more like where my cycling should be, I found Tony's Tasmanian Cycling blog the other day. He has an electric assisted Greenspeed and pootles around and has fun. Some nice, gentle blog posts here.
