Nawa's stylish e-motorbike uses an ultracapacitor to drastically boost range
A company called Nawa has unveiled an electric motorcycle with a racy hubless rear wheel and a lot more range than most other e-bikes. However, the one-off "Racer" prototype is actually designed to help the company show off what it really sells: ultracapacitors. Above the 9 kWh battery is a 0.1kWh ultracapacitor that can harvest 80 to 90 percent of the braking energy, much more than lithium-ion batteries alone can store. As such, it can go 300 km (186 miles), compared to 180 km (110 miles) for a bike with the same battery pack alone.
