For those interested in this 200. SportsDirect had £40 cashback making it £180. Not bad considering the Nexus 7 goes for about £120!

The rear hub is where most the money goes, and the frame. Both are excellent. I suspect the frame is made by Dahon. There is no mount on the front because it's aluminium and would snap.

The bearings in the headstock will need immediate replacement (mine lasted one hour). Standard 5/32 size. Could swap out the whole thing (it's a £5 NECO unit).

The BB is a joke, it is supplied seized by design and should be immediately swapped. It's a standard 68mm square taper (though the supplied BB is some makeshift crap - truly inefficient). The crankset is workable but I found the 46T to be a little too high. It can't be swapped without replacing the arms. Better off saving a nice 500g with a replacement HT2.

The seat post is quite short (550mm). It has an insert so you can swap to a standard 33.6mm post and can save a further 300g here as the seat bracket is very heavy (cast steel).

Brakes are solid. Plenty of mild steel here so will rust eventually but ok. Levers are aluminium.

Wheels are 36 spoke and unless the rims are really thin then these should be bullet proof.

Mudguards are light weight, as is the rack, steering post and bars. All good here.

Pedals are poor, quite wobbly and bearings are also terrible.

The Nexus 7 was set up pretty well and is silky smooth. It's made in Japan which is where Shimano makes all it's high-end gear (XT, XTR etc) and I suspect it will last a while.

I've attached a picture of mine at the start of modifications.
