Repair advice needed for childs bike

[planet head]

A very simple solution to some that knows. My sons bike rear wheel is not turning freely, when pedaling or freewheeling. It is making at quite hard work for him to use his bike. I have turned the bike upside down and spun the wheel by hand, and it stops rotating very quickly both ways.
If any one has got any tips it would be great.
many thanks

thanks for the reply. Just checked, the pads are not rubbing still have the same problem, this bike has no gears if this helps

Check the cone nuts on the rear wheel.

If they are too tight the wheel will not turn freely.

Have a look at this and see if you can locate the problem!

is the wheel slightly buckled, causing the tyre to rub on the frame (as opposed to the blocks on the wheel)?

Cone nuts are too tight. The can tighten themselves if they're not set up properly, especially on lower quality bikes, of which most childrens bikes seem to be.

If you take the back wheel out, can you rotate the axle easily?
