The HSD-like system will replace the existing transmission. My idea is to separate the pedal power from the electric boost/regen. In other words, the bike will just work like a normal bike if the twist handle is in its center position, only regening slightly while pedaling to make up for the small amount of power used to run the electronics. If the twist handle is in accelerate, it will use the battery to add power. If the handle is in regen, it will regen while charging the battery. The "gear shifting knob" is used to change the virtual "gear ratio".

However, since it is coordinated in software, it can also operate in fully automatic mode. With more processing power than a 486 (in the Parallax chip), the possibilities are nearly endless!
