I'd imagine this is the sort of thing the Dark Night would use as a last resort. If the Batmobile, Batwing, and even Batpod, were all out of commission, he'd still be able to run down baddies at 20mph using this petrol-powered motorboard.
The 26-kilo device is powered by a 2HP, two-stroke engine with enough power to tackle 15 degree hills and support a 90kg rider. The front footwell moves side-to-side, which steers the board, and a tethered hand-throttle/brake handles the acceleration. Its 1-litre tank holds enough fuel to hunt down fugitives in a 20-mile range. It retails for around £320 at Hammacher-Schlemmer.
I dunno though, as cool as it looks, I would not be able to keep a straight face if I saw Batman bearing down on me riding this. It'd be too much like getting chased by Segway-mounted shopping centre security. [HS]
