Retro Direct Bicycle. Pedal Forwards or Backwards to move Forwards, at 2 speeds without shifting.

This is my first attempt at a Retro Direct. This bike has 2 chain rings, 2 freewheels, and 1 chain. You can propel your self forward by pedaling either direction, while coasting is still possible. Pedaling backwards will give you a 46 x 17 gear ratio where pedaling forward will get you a 46 x 15 gear ratio, for faster speeds. I am using a 1990’s AlpineStar Cromega frame with an elevated chain stay. I chose a frame with an E-Stay to get the chain stay out of the way of the chai
