I have just purchased a replacement battery for my electric bike which is different and bigger than the original one fitted.

The battery is labelled as XH370-10 Phy-Lion which aparently is used by Alien Bikes?

I am thinking that it would be best to purchase a rear battery rack for this?

I have looked on the Alien Bikes website but have been unable to find what I'm looking for.

Can anyone help or advise?
