Hydraulic brakes - 12ahr bottle battery - 350W controller - half decent other bits - seems pretty good at £850.Looks very good: Well specified for that price point.
There was a Mosso bike on ebay back when I was looking at Kudos bikes & it looked a serious contender at £1300:
But further down the listing, the uk version with vat & shipping was £1600.
This one looks to be all inclusive at the lower price.
