I built my first gas bike when I was 12 I'm 56 now I have been riding 2 wheels most of my life.Yes it can be dangerous,but what's life if you don't scare yourself silly every once in a while.The answser is very boring!!! I agree the instructions and the hardware
in these chinese kits suck. You should at least make a solid front mount . As for my current bike (walmart schwinn del mar with 66cc 2 stroke )I love it!! When it breaks
it just gives me a chance to excercise the gray matter and make it so it doesn't do that any more.I have only logged about 20 miles and it has broken down about as many times.
And hey if you crash the pain lets you know your still alive.
