'mr millie' here: if you are 16 stone i really would recommend someone slacking off and re-tensioning the wheels before you ride it. In my book, the front one was just about laced together rather than 'built' and would have lasted about a week under my weight. Sponging-machine from this parish is roughly your dimensions and once destroyed a cheap rear wheel on his box-fresh kona riding up whyte's level. Poor bugger had to walk back down it…
Also the grips spin on the bars, the back mudguard rattles (I drilled a hole and put a bolt through the sliding seatstay bridge mount), the bb is sort of cartridge but sort of cup and cone wierdness, chainrings riveted not bolted on and the saddle is a sofa.
Still, excellent value nevertheless, the rest of the kit is quite servicable, especially the frame and fork, if you pump the tyres all the way up to max pressure (60psi iirc) its fairly quick for a 32 lb-ish bike. Oh and it even comes with a little bottle of touch-up paint. :-)
