8-speed cassette/adapter for Swissbike LX?

I have a Swissbike folding mountain bike.  That looks to have an 8-speed cassette.  Full spec is here:

Will I need any kind of adapter (e.g. axle adapter?) to use with my Neo (due to arrive tomorrow).  Or is that likely to work 'out of the box' as it were?

Presumably I will need to install an 8-speed cassette e.g. https://www.amazon.co.uk/Shimano-Cycling-Cassette-HG31-Speed/dp/B003EQ96SE/ ?


Thanks,
