When I went to pick up my bike, I got a slap on the wrist.
My gears were out because my back wheel wasn't on properly. Rookie mistake!
I'm not really sure why my back wheel keeps coming loose, but I must remember to check this!
I think I previously thought the quick release didn't have to be on very tight, so I maybe had them on loose.
Silly me! I should check this from now on!
