Nawa’s ultracapacitors e-motorbike Racer has a racy hubless rear wheel and more range than most other e-bikes have. The one-off “Racer” prototype is designed to help portray what the company really sells: ultracapacitors.
Above the 9 kWh battery is a 0.1kWh ultracapacitor that can harvest 80 to 90 percent of the braking energy, far more than lithium-ion batteries alone can store. With that, it can go 300 km ”186 miles”, compared to 180 km ”110 miles” for other bikes with the same battery pack.
The Nawa’s ultracapacitors e-motorbike Racer will never be sold, not now, not anytime that we know of. Nawa only wanted to show what its latest ultracapacitors can really do. The company also created a split “tank” which was design with the ultracapacitor unit in the top slot, while the regular battery stays down below.
The ultracapacitors which wewre built of carbon inexpensive and weigh about 10 kg, yet they boost range by up to 65 percent or there about. Achieving same result with a regular battery would increase weight and cost.
The technology will best serve in stop-and-go city driving. “It only stores a small amount of energy, but it’s being used very efficiently. We’re basically pumping that ultracapacitor in and out the whole time through acceleration and braking.” Nawa CEO Ulrik Grape told New Atlas.
The Nawa ultracapacitors e-motorbike Racer is very fast, and is able to do from 0-62 mph in “comfortably under three seconds,” according to Ulrik Grape. Nawa will showcase the Racer at CES 2020 as an illustration of what it can do, and will start working on producing the ultracapacitors at large scale from 2020.
“There is no reason why this cannot be applied to a larger motorbike, or car or other electric vehicle. And what is more, this technology could go into production in the very near future,” Ulrik Grape said in a statement.
