Motorbike Movement

Hi, a couple of weeks ago i exchanged 500 pve coins for a blue motorbike , i was so excited and i went to try it to find out that it jumps up and down every few steps like it has a flat tire or its going to breakdown, it doesn't move like a motorbike should, of course i was very upset because i waited too long and worked very hard to get it, and now i don't use it because the way it moves is annoying, and i can't even sell or trade, all i'm asking is to change the way motorbike moves to run on the ground like the bicycle instead of jumping up and down, have a nice day.
