seeking sheaves in UK

Hello, just joined, first post here!

I'm very keen to purchase a sheave (I believe that's the term), that will mount on my bicycle's rear wheel spokes, so that I can attach a belt to it. I want to use it both as a power input and power output as I'm fond of driving things by pedal power.

I notice that this component is available through this website, but it's out of stock, and will cost a lot to ship from US to UK.

So, anyone know where I can pick one up in this country please?

Very glad to find this community, I'm deeply impressed.

Thanks,
Matt

Hi Brad,

Many thanks for the reply. I hope it will lead me to purpose-made components that will properly fit with one belt type or another, rather than just an adapted wheel rim etc.! Hoping to get the max coupling possible, not just a scrapyard challenge
