Thanks Peter. I had to remove the back wheel to put in a new inner tube. That must have caused it. So the wheel should spin freely just like on an ordinary bike? I forgot to mention the bike is a Carrera Crossfire.It should spin freely - something maybe rubbing - brakes ? Turn it upside down and look carefully and see if you can identify what is rubbing against what
A Crossfire wheel should spin just like a normal bike but only in the forward direction. When you spin it backwards, there is some resistance from the motor, so it'll do maybe one or two turns from a good spin.Good question. Possibly not. I'll investigate. Many thanks.
