The Nawa company has unveiled one electric motorcycle with a sleek hubless rear wheel and a much wider range than most other e-bikes.
However, the unique Nawa "Racer" electric motorcycle prototype is actually designed to help thecompany show what really sells: ultracapacitors.
Above the 9kWh battery is a 0,1kWh ultracapacitor that can collect 80 to 90 percent of the braking energy, far more than lithium-ion batteries alone can store.
With this configuration, Nawa can travel 300km compared to 180km for a motorcycle with the same battery pack but without supercapacitors.
The prototype will never be sold, but Nawa wanted to demonstrate what his products can do.
To best show the technology, he created a "tank" design separated in two: on the top the super capacitor, on the bottom the regular battery. Ultracapacitors are relatively inexpensive and weigh only 10 kg, but they increase the battery capacity by around 65%.
To get that kind of autonomy a normal battery would have to drastically reduce weight and cost.
The technology is more effective in city driving, characterized by frequent braking and restarting. "It only stores a small amount of energy, but it is used very efficiently," they say in the company.
The Nawa Racer is also quite fast, able to easily go from 0 to 62 km / h in "less than three seconds," according to Grape.
Nawa will showcase the Racer at CES 2020 as a demonstration and will start producing the supercapacitor on a large scale starting in 2020. "There is no reason why this cannot be applied to a larger motorcycle, car or car. another electric vehicle. This technology could go into production in the near future, "Grape said in a statement.
