Minor electric shocks from bike when connected to Neo 2

Hi guys

When my bike is connected to the trainer I get very small electrical shocks from it. If I run my fingers over the surface of the frame it feels like it's vibrating. 

There is nothing else electrical connected near or to the bike. It's 100% coming from the trainer. Everything about the trainer seems fine apart from these minor shocks hahahaha. 

Anyone else have this?
