Just curious, I noticed a few days after getting the bike that my rear right side wheel had a bit of play in it, like a credit card was pulled out of something and left a bit of play when grabbing the wheel at the top and pushing in/out on it, while the rest were all tight like a tiger.

Tonight, it felt like it was 1 and a half credit cards of play after a quick hard run to the country store and now left side in the rear has play like right one did when new. Is this a normal behavior as the bearing get broken in some?

I don’t mud it but hit the occasional puddle and definitely do not play in the sand.
