Segway bought the "export" rights from Surron, Luna will most likely run out of stock or continue sourcing from surron, wait and see.
Luna has had a history of changing prices for surrons quite dramatically as well. I remember seeing a promo on luna for a sub 3k surron.
Back in 2016, these bikes were purchasable from China for around 2500 delivered.
I don't advise you buy from the indigogo, it's a bit retarded. Do more research, consider building your own...ddm11x dualtron etc
I don't appreciate segway's retarded two payment bullshit, I don't like the final price either. Don't buy.
