I built up my yellow Fnhon STORM recently. The frame is made of CrMo 4130 steel, so it is not very light, approx. 9.4kg w/o pedals.
It is considered to be a leisure bike for short distance riding, so not many widgets are installed.
It has flat bar, ETRTO451 wheels, hydraulic brakes and 10s drivetrain, which together provide a brisk and agile ride.
Very nice! I think I'd probably destroy those wheels in about an afternoon and a half of riding though.
