British company econogo has launched the yogo, the first electric scooter that uses a fully detachable and portable lithium battery. Traditionally, electric two-wheelers in the UK have used impractical fixed silicon batteries which require the owner to run an extension lead from a mains electricity socket to the vehicle’s integrated battery. yogo owners can remove and charge the two LiFePO4 batteries inside an hour. Two spare batteries offer the option of an instantaneous swap for a further 44 miles of range. The GBP1999 (USD$3000) yogo has a 1500W motor, a top speed of 38 mph giving it the acceleration of a 100cc motorcycle, if not the top speed … and almost negligible running costs.
