unfortunately i had the battery problem also but didnt post about it before the deadline.it used to propell me to work a distance of 9 miles now im lucky if it does 1 mile. but as its only 4 months old its covered by a 6 month warranty.ive contacted 50cycles they said ive to send it back for checking.he said hes been put in a sticky position regarding postage costs.i said i will pay the postage no problem.fingers crossed i will get a new one.
