Look at that asshole, Tim trying to sell people 'patents', that are
totally free at the patent website.

Here are all the free patents you can print up for free, with the
word 'bicycle' in the title of the patent.

This is a much better search than 'bicycle' in all fields.

I know what you are saying about angular velocity, but still, you
would be applying your effort at the maximum torque angle over the
'meat' of the rotation, maximizing power to turn a larger sprocket
faster than you could.
