Acorn Freestyle Hub Help

garethgeezer:
Just fitted some 16" Acorn Freestyles to my son's bike, they look great but he is very disappointed as after about a mile of riding the freewheel started to play up - it slipped then locked up, slipped again etc etc. Easy I thought, until I got home and checked it out. It is a Sturmey Archer hub, I think, so it does not have a normal BMX freewheel but is more like a shopping bike hub. It has 'SA' stamped on it, also 'AW' and '85'. There are tabs that locate the hub into slots on the wheel centre and the whole thing is secured with a circlip on the other side.
I don't know how to fix it. Does anyone have one of these they don't need that they would be kind enough to sell to me? or does anyone know how to replace/repair the freewheel part which I'm guessing is inside the hub? Thanks!
Any help or advice would go towards cheering up my son :)

That looks like a coaster hub to me, minus the ancor arm.

garethgeezer:
I did consider that, but there doesn't seem to be anywhere for an anchor arm to go, plus it sounds like a regular freewheel when it is working. Anyone else have this sort of hub on an Acorn wheel? Anyone else got Acorns?! (I know they're not very popular)

If you dont have the coaster arm on , i expect it will rotate like a freewheel

On the advert, it says

Rear Sprocket thread : 1.37 inch x
24 T.P.I. suitable for all standard
sprockets

So i would expect a normal freewheel.

I might have a review of Tuffs v acorns so i will take a look
