Hi
I have just ordered an Atto sport mobility scooter – it folds up to the size of a carry on bag and can then be divided into two pieces to lift – 12.5kg and 17kg. If you can manage on a scooter it’s worth looking at – I can’t recommend it in person yet as (like most things) it’s waiting to be unloaded at a port somewhere. I was surprised at how many options I had for similar scooters but none are cheap.
