Lightweight 'legal' kit then, if it's just to turn on occasionally for a bit of help up a hill off-road without being a beast round your neck most of the rest of the time when you want to ride unpowered on flat / DH.
It won't have 'grunt' but it'll take the edge off the effort and allow you to ride the bike on-road under 'amnesty from prosecution' until new rules come into effect. On flattish terrain you don't need high powered motors unless you want to ride fast and unless for initial acceleration most likely won't really need a motor at all.
