It doesn't seem too long ago when we were reporting on breakthroughs in battery technology that would allow electric motorbikes like the Brammo Enertia to travel as much as 45 miles (72 km) on a single charge. These days, we're seeing most of the recent arrivals (such as the 2012 Zero S range, for instance, or the gorgeous custom-built Brutus 2.0) flying past the 100 miles (160 km) barrier with relative ease, a range long enough to quieten even the most fervent of petrol-heads. Two Purdue University engineering students have recently completed the conversion of a Yamaha YZF600r to electric power that further pushes the envelope to more than 120 miles (193 km), using batteries cooled by phase change material.
