A few things
I’m also on the Wirral (Bebington, where are you?), will deffiantly keep an eye out.
Feel for you mate, we had 2 go from our garage a while back. Do you think you were targeted or just unlucky? I was more than likely followed, probably from Degla (there was a lot of it going on at the time). One of the lads I ride with had his go in exactly the same way a few weeks later. His was actually found in a bike shop in Liverpool, although due to rubbish police response time it was never recovered.
Another mate has had 2 bikes go from the Wirral on Tuesday night, although cheaper Treks and he hardly ever uses them, but could easy be the same scum.
