Back wheel stopped clicking

[mike_90]

Heya,

When i walk alongside my bike the back wheel doesn't click and the pedals go round

Also, when i freewheel the chain backs up and the bottom part of the derailer pulls forward.

as you can tell i'm a novice but i'm pretty sure these problems are related any help would be greatly appreciated

Thanks

Mike,
Welcome, that sounds like your 1. Your Freewheel/Cassette is in need of replacing 2. Chain may need replaced. 3. Not sure of this, but the derailleur may need adjusted/lubed.

Sounds like the freewheel / freehub has seized? The pawls have rusted / jammed.
Try squirting some release oil into it.

But before that, check that nothing has got jammed behind the big sprocket and the wheel spokes.
Some cloth or string etc?
