A lot of e-bike publicity focuses on the performance capabilities of the motor or the size of the battery. One often-overlooked area is gearing. Surely you just get the same choice as on a regular bike? Only to a point; the e-bike revolution has meant many things for e-bike design, one of which is an expansion of the gearing options available. With extra motor power available bigger and better performing gears can be used, gears which would be too heavy or
difficult to pedal for most riders of non-electric bikes. These are covered in the Advanced Systems section later in the article.
