Hey guys,
I bought a bike similar to that one from the same people (woelfe_sport) a few months ago and despite gazza and eatslikehomer having a few troubles with theirs, i can honestly say that i have had no problems whatsoever with my bike.
My mate actually got exactly the same as that one pictured except blue, and we went out last weekend on them and it seems to be not too bad - my engine has the Zongshen cover on it, and his doesn't. We had a race up the street and i pulled away from him a fair bit - his bike is a fair bit noisier than mine so i'm guessing the newer ones from them have different engines although the specs sheet they provide is the same.
The other differences are that the one pictured has the wave blade brakes which don't seem to make any difference just for looks really, also those ones have the adjustable gas shock on them compared to mine which is just a standard yellow spring. We set my mates shock at the lowest, yet the bike is still considerably higher than mine, and he was complaining about it on the weekend because he felt too high up. I spoke to him yesterday though and he reckons that it has sunk in a bit now and doesn't feel so high anymore.
The wheels/tyres on these bikes are also pretyt good as they are 14" front and 12" back, whereas alot of the others are 12" front and 10" back - they arent as "mini" as a lot of the 110cc bikes, but they are still pocket sized compared to normal dirt bikes.
One downfall i'd have to say with the bike is that the seat is rather thin so after 4 hours of riding you have a bit of a numb ass but it feels like my seat has loosened up a bit since i first got it.
As for price, i got mine for $760 + $100 postage, and my mate got his (the exact same as pictured there) for $830 + $100 postage.
Hope this helps!!
Cheers,
Macka
