I can't use my left arm - the fingers don't work, my wrist is fused, and my elbow dislocates if pressure is put through it. Its also very painful.
I can, and do cycle, using a wrist brace, full arm splint, and no back brake or front gear cogs, plus a hybrid bike adjusted to let me just rest bad arm on the handlebars.
But as I cycle more, and want to go faster, this isn't ideal by any means, and I could really do with some help.
If anyone had any words of wisdom, I'd very much appreciate it
