Austria's wild one



The BBC has an article about a new bike from Austria:
The Johammer J1 (photo, top), which bears an undeniable resemblance to the Imperial speeder bikes (photo, bottom) in Return of the Jedi, is hardly the first battery-powered motorbike, but it is among the few capable of traveling over a hundred miles on a single charge. This sort of stamina– roughly equal to that of a gasoline-powered bike– elevates the J1 from the status of Saturday morning toy to bona fide road-tripper.
Though it may be tough to stop staring, the J1’s innovative features go beyond its slippery neo-retro body fairing. The bike has no traditional gauges: speed and battery level are presented within a pair of high-resolution two-and-a-half-inch color displays mounted within the round rear-view mirrors. The steering is of the exotic hub-center variety, which separates steering, braking, and suspension forces for improved stability. And the body offers two foot-peg positions (unlike a traditional motorbike, the J1 has no foot controls), providing a choice between hunkered-down and laid-back riding positions.
The Johammer bike may be stylish, technically advanced, and energy efficient, but fast it is not. A compact 11kW electric motor mounted in the rear wheel hub provides the motivation; matched to a single-speed transmission, the motor’s fourteen horsepower are tasked with moving upwards of four hundred pounds of bike, plus rider. The J1 is electronically limited to 62mph.
Providing the charge is a centre-mounted, 12.6kWh stack of lithium-ion battery cells, developed and manufactured by Johammer itself. The company claims the pack will retain at least 85% of its capacity after four years or a hundred thousand miles miles. Recharge to eighty percent takes nearly four hours from a 240v socket, or just eighty minutes with the optional 400v charger.
No surprise, straddling the future isn’t cheap. The J1.150, with a smaller battery pack and a 150km cruising range, commands about twenty-three thousand euros; the beefier J1.200 will set its rider back twenty-five thousand euros. For the merely curious, Johammer offers some quality time on the J1, via a two-hundred kilometer guided tour of northern Austria (including a stroll through its factory in the town of Bad Leonfelden), for three hundred euros.
Rico says he's quite sure it's green, but it won't sound the same... (And Marlon Brando, though he's already dead, wouldn't be caught dead riding one.)
