And anyway, I have no idea what an ultracapacitor is (were they used in Back To The Future?) but it sounds incredible.

This Sixties-inspired electric motorcycle is hiding some properly groundbreaking tech, or so says its maker. Set to be revealed at January’s Consumer Electronics Show in Las Vegas, NAWA Technologies’ ‘Racer’ uses a hybrid battery, which mixes conventional lithium-ion cells with ultracapacitors.
Yep, ultracapacitors. NAWA says its carbon-based ultracapacitors mean faster charging, better energy regeneration (up to 80 per cent), more performance and range, a longer-lasting battery and less weight. “The efficiency improvements made by a hybrid ultracapacitor battery system,†it says, “can reduce the size of the lithium-ion battery by up to half, or extend the range by up to double.â€
The Racer’s fuel tank – or where you’d normally put the fuel, were this thing powered by internal combustion – contains the ‘NAWACap’ ultracapacitors, while the 9kWh lithium-ion battery (half the size of a normal electric bike) is where you’d expect to find the engine. The whole thing weighs 150kg, which is 100kg less than a Harley Livewire (that’s a proper production bike, though, not a flimsy concept).
