I rode Taffy's new FE570 a few months ago and loved it.
It may well be my next bike.
It is the same weight as my 510 husky (114kg ish) but it felt so much lighter.
It was set on the lowest power setting but was still plenty for me.
Loads of low down torque - I was in 2nd, at little more than walking pace and it chugged up a rocky climb without even a cough.
Also it is quite a tall bike which suits me as well.
Taffy will probably be on here soon singing it's praises and explining from a techy viewpoint about the crankshaft position etc
Go for it
