Range varies based on factors that include rider weight, terrain, air temperature, and wind resistance, not to mention the selected power setting. You also have to consider trip duration. During an hourlong off-road loop in the rain-moistened hills of Southern California, we had over two-thirds battery capacity remaining. This was while running the most aggressive EXPW power setting on the YDX-TORC. We experienced less power consumption aboard the road-based CrossConnect, CrossCore, and UrbanRush—albeit over less strenuous and mostly paved bike paths.
