What Customers Are Saying
I got my 49 cc 4 G T back in March of 2012.
I love it. I ride my bike 30 miles one way to work everyday. I have over 2000 mile on my engine.
It still works like the day I got it.
The technical support I got from Robert over the phone and vie E-mail was awesome.
Everybody stops me and ask me about my bike.
They all love it.
Kit was sent to me without the oil lite bushing needed . Now i need other parts like the clutch witch im told may come from china someday maybe if it clears customs this LATE summer some time.With only a few weeks of summer left i wish i had never bought this without support or replacement parts this kit isnt worth anything.SOFT HARDWARE AND NO WAY TO GET PARTS ADDS UP TO A PILE OF JUNK.
I changed to the belt drive 6 or 7 months ago.Was the best thing I ever did. The help over the phone was great. It solved some problems and made none. Fantastic.
You're better off paying more for a better kit or just going with a 2 stroke kit that is way less maintenance
