Read the specs:
Not too heavy (good)
Alloy frame (good)
Unnecessary bouncy fork (bad but the norm)
V brakes – check the levers are metal and adjustable
Gripshift – I prefer rapidfire, but kids find this easier (“forward to go faster”)
Standard headset (neutral really as you won’t be changing the forks)
For £200, it offers similar ability to the more expensive Trek/Kona/Specialized offerings. Won’t hold as much value as an Islabike. But it’s a good bike that you can easily throw round a trail centre.
I’d buy it over the Zombie, which has a steel (read Lead) frame, but you may do well to look second hand for a Kona Hula, Trek MT220 or Specialized Hotrock. There really are no poor bikes once you go beyond the Steel framed, plastic levered, dross.
