Abstract:
An automatic bicycle drivetrain shifting apparatus comprising a bicycle drive chain derailer apparatus powered by a servo gearmotor and controlled through a highly adaptable user interface serving to automatically alternate drive chain position between available bicycle drive sprockets based on user preset and in real time modifiable criteria and additionally making use of critical chain driver apparatus serving to ensure chain motion is always available to satisfy derailer operation requirements often prevalent during coasting and stopping where the bicycle speed changes while pedaling motion has ceased.

Claim (Index 10):
10 - An automatic bicycle shifter and chain driver apparatus comprising:\n a) a bicycle rear wheel hub drive chain derailer powered by an electrical gearmotor including a rotational position encoder, b) said bicycle drive chain in constant engagement with one of a plurality of a bicycle rear wheel hub power transmission drive chain sprockets, c) an electronic control system with a hardwired connection to said rotational position encoder and including a shaft angle resolver, a revolutions counter and a nonvolatile memory for storage of readings of said rotational position encoder corresponding to alignment positions between said bicycle rear wheel drive chain derailer and said bicycle rear wheel hub power transmission drive sprockets, d) said electronic control system further including a servo motor controller with a power connection to said bicycle drive chain derailer gearmotor, e) a bicycle speed sensing means producing an electric signal in a known relationship to road speed of said bicycle and including a hardwire connection to said electronic control system, f) an electronic user interface for entering readings of said rotational position encoder corresponding to said derailer alignment positions and corresponding speed shifting thresholds of said bicycle drive chain derailer into said nonvolatile memory of said electronic control system, g) said rear wheel hub including a rotationally affixed connection to said plurality of rear wheel hub power transmission drive chain sprockets, and h) a pedals forward clutching apparatus fitted for actuation of said drive chain and consequent power transmission to said bicycle rear wheel hub power transmission drive sprockets upon a forward pedaling motion and slip upon actuation of said bicycle drive chain driver, Whereby said electronic control system commands said gearmotor of said bicycle drive chain derailer through said servo motor controller to seek and hold said encoder readings corresponding to said derailer shifting positions upon said bicycle speed sensing means relaying said corresponding bicycle speed derailer shifting thresholds are reached notwithstanding lack of actuation of said pedals assembly with said rear wheel hub affixed connection to said plurality of rear wheel hub drive sprockets forcing continual forward motion of said rear wheel hub power transmission drive chain sprockets and said drive chain during coasting, braking and inadvertent acceleration of said bicycle permitting operation thereof of said rear wheel hub drive chain derailer with said pedals forward clutching apparatus inhibiting consequent power transmission to said pedals.
