Hi guys, just joined. Had rockets for a few years, now disabled so riding a rocket trike and loving it.

Anybody any idea where I can get a rider seat back rest in the uk?

Is that a Grinnall trike ya got there? The reason I ask is that the trike seats have been altered to accommodate the conversion and a bog standard seat may not fit. I had to do a lot of work to fit mine (attached) down in London.
