In-line skating commuters may be joining motorists in petrol station queues with the introduction of Power Blades - a pair of aluminium frame in-line skates weighing a total of 7.2kg with a 22cc engine attached to the back of the right skate. The US made skates utilise a precision single-speed drive gear to the rear wheel achieving a maximum speed of approximately 35kph. Acceleration is controlled by a hand-held throttle and braking is standard rear drag - and if you do happen to run out of fuel - just skate on.
