I thought my Powabike was Mk 1 the side covers just lift off the motor. I wondered why I was not getting any replies,and it was posted in the wrong forum..I found that the wires coming from the wheel had been almost cut and badly frayed. I want to replace them but I don't want to damage anything. What side do I tap the spindle on to get the motor out of the wheel, and any tips on servicing would be appreciated.The bike is older than I thought but the motor works and looking at the tyres hardly used.,shame not to revive it. regards
