i just attempted putting pocket rocket wheels on a mini quad, but the inside diameter of the bearings are too small on the pocket rocket wheels.....
am i able to change these over some how? the outer diameter is the same.

ok i was able to knock out the bearings of the pocket rocket wheel and ill stop in at bunnings this arvo to try getting some, they only have to be 2mm bigger on the inside.....
and then this afternoon ill put them in and hopefully they'll work.......
