The R&M are well built, easy to ride and very comfortable. You will need a geotechnical assessment for your storage space though, they're about the same weight as a house.
it'll be in our garden, on top of woodchip (with two concrete sunk ground anchors for security) so shouldn't be a concern. Maybe actually a bonus if there's no battery in there it might be harder to steal?
haha! wife wants 3... i'm hoping to convince her that we can do 2 safely
