Automatic Bike Transmission

The goal of this project was to create an automatic transmission for a common
bicycle. This system must shift the bicycle smoothly through the gears on the bicycle. In
order to determine when to properly shift the bicycle, the transmission must incorporate
input measurements of torque applied by the cyclist, pedaling rate, and bike speed. Also,
a manual mode should be available so that the rider can have full control over gear
shifting. An effective user interface must also be incorporated into the bicycle so that the
rider can see his/her speed, current gear, and change between manual and automatic
mode. The user interface also functions as an odometer that measures current speed,
average speed, and distance traveled.
