Lost bicycle left outside a café near Cardiff Castle on the Taff Trail, with a unique sticker on the frame and a slightly worn front tire.

I was biking along the Taff Trail near Cardiff Castle when I stopped for a moment, and I guess I accidentally left it outside the café. It has a unique sticker on the frame and a slightly worn front tire. I really hope someone has seen it or can help me find it. It's very special to me.
