1. A motorized bicycle, comprising:
- a frame;
a plurality of wheels coupled to the frame;
a plurality of pedals coupled to the frame for driving at least one of the plurality of wheels;
a plurality of gears coupled to the frame, each gear being associated with a different speed range;
a motor coupled to the pedals and at least one of the plurality of wheels to drive the least one wheel;
a battery for supplying power to the motor;
a shifter;
a cable coupled to the shifter and to the plurality of gears;
a derailleur coupled to the plurality of gears;
one or more gear sensors coupled to the cable to detect a position of the cable; and
a controller that determines a position of the derailleur using the position of the cable, the controller further detects a current gear higher than a previous gear of the plurality of gears of the motorized bicycle using the position of the derailleur, the controller further regulates a power output from the battery to the motor based on the current gear to cause the motor to drive the at least one wheel to propel the motorized bicycle to travel within a speed range associated with the current gear,wherein the controller interfaces with one or more biometric sensors and considers measurements from the biometric sensors in adjusting the power output from the battery based on measurements from the biometric sensors.

Abstract
A motorized bicycle includes a frame, a plurality of wheels coupled to the frame, pedals coupled to the frame for driving at least one of the wheels, gear(s) coupled to the frame, a motor coupled to the pedals and at least one of the wheels; a battery for supplying power to the motor; and a controller. In response to a selection of a current gear, the controller regulates a power output from the battery to the motor based on the current gear, where the motor propels the motorized bicycle to travel within a predetermined speed range associated with the current gear.
