Thats not the newest one though. This one has no chain and longer riding time.
£10 off not 10% if my maths serve me right. Just to throw another option out there https://www.amazon.co.uk/gp/offer-listing/B000P7BMR8/ref=sr_1_1_olp?m=A2OAJ7377F756P&s=warehouse-deals&ie=UTF8&qid=1481921661&sr=8-1&keywords=e100&condition=used. Used like new. I got one for my daughter for Christmas last week off amazon warehouse for £63. Stated slight damage to box. Arrive on Wed, couple of minor marks on box, never been opened. Sides were still glue held. I know this is the newer powercore model, 1mph faster and slightly improved runtime. Still a decnt deal though OP. Heat.
