is that correct, 5-8 yr old with a 20" frame ?????
20" Wheels not frame, adult wheels are 26".

...seems ok however it seems a bit strange to have disc brake only at front and normal brake at rear?? Surely this will; mean the front brake is stronger. Other bikes i've seen with disc brakes such as dunlop at sports direct have 2 disc brakes...
This used to be the norm on cheap adult bikes. The front disc is only cable operated so isn't a huge upgrade over rim brakes (except they don't rub when you buckle a wheel, which is harder on a 20" wheel than a 26"). Cable discs, unlike hydraulic, require frequent adjustment and aren't as powerful. Most of the weight of the bike shifts to the front under heavy braking so a front only disc does almost make sense when cutting costs, heavy braking on the rear will more likely result in locking the wheel which isn't helpful. The modulation on a disc brake is better, ie it's less "on" and "off" than a rim brake, so going over the bars when the front wheel locks is less likely.
That said, if it was me I'd get my child a cheap BMX bike, easy maintenance, bullet-proof wheels, single gear makes them exercise more, and it encourages the learning of skills like hops, manuals, drops and jumps which will stand them in good stead later. Don't be blinded by the rear suspension on this bike, it is virtually useless, reduces pedal efficiency and is incorporated at the expense of the other components. Less is often more.
