So I have got a XRated Mesh Jump Bike and I want to change the crank to a smaller one and I was just wondering if this would be possible as I have heard that xrated is Apollo and you can’t change the crank thanks for the help.

You can change the cranks, but you may need to change the bottom bracket as well,
a lot of cranks come with a bottom bracket when you buy them

Are you looking for a shorter crank or a smaller chainring?

Both because the Crank coming lose is a common problem for these bikes
