Oh Gosh, Ty...
I think I might have given the wrong impression???
Let me try again.
With these HT/Chinagirl bicycle engine kits, it's ALL a crapshoot.
Guaranteed !!!
Price, advertising, displacement, laws, etc... none of it makes any difference in what you may really get when your box comes in the mail.
And even that changes when you go to assemble it, and MORE changes when you go to attempt operation!
...yet it could all go like a dream!
There is no telling.
Perhaps the best thing would be to purchase a kitbike from one of the sponsoring vendors. As a rule, they make an effort at integrity, when it comes to support.
So, you will need to balance out your possible/probable need for support against initial price outlay.
Truly, it's an adventure!
If you can't do this for the entertainment value, it's just not going to work for you.
Personally, I have enjoyed participation here on the forum as much as riding the motorized bicycle.
Good luck
