Having just purchased a bike from juicy bikes in buxton, i wonder how long would this battery last? battery is 36/10amp, they say it will take around 800 or so charges? i did around 15miles today first time out and still had 2 lights on when i got home, very pleased with this bike its the 2011 sport, for the price its great i will do a review later in the year, Cheers Rob.
