One of my mates bought one of these for his 6yo son. not sure if it was the same dealer, but then most of these bikes come from the same source...
It lasted about 6 weeks before it started giving trouble. He replaced some parts under warranty but the customer service was terrible. He then got sick of it and put it aside in his shed until the warranty period ran out! He came to me at the start of summer 2014 to see if I could do anything to fix it... I eventually got it right but by f*** it took a fair amount of time and effort.
Advice if you do buy one -
Don't ever let it get wet.
Don't run it on hard ground for fear it'll fall over, the aluminium engine casings are brittle and shatter on impact.
Don't ever forget to premix the 2 stroke oil with the petrol.
Don't ever let it run out of petrol and -
DON'T let any fatties ride it!! The bearings and bushings are made of chocolate...
I'd rather go to a Jedward concert than put a spanner to one of those Chinese kids scramblers!
