The a-bike seems to be aimed squarely at urban commuters, but there's many other markets perhaps.
I took my a-bike to a race meeting at Donington Park at the weekend, where it attracted a lot of attention (about 2/3rds good and 1/3rd derision). Lots of other competitors fancied one as a paddock bike - one commented that he'd bought a £3k trailer to bring his normal bike to the circuits (but we need different colours, as I saw someone on an a-bike and thought they'd nicked mine!). Lots of Caterham owners like the sound of one for putting in the boot for getting around at places like Le Mans. And one of my friends reckons it'd be perfect for carrying in his light aircraft. Anyone from Mayhem read the forum??
