Re: Hello from Ga.
Welcome Denro. We're glad you've joined our ranks. You'll get lots of opinions on 'the best kit'. People usually suggest whatever they have had good luck with. Persoanlly I feel that the $600. price tag is on the high side. I've never spent that on any kit and I have thousands of miles on the ones I've bought for less that $200. Do some research and look at the many alternatives to choose from and consider what you're looking for in a motorized bicycle. Novelty, occasional fun ride, daily transportation? It all depends on your expectations as to how much to invest in the project.
What part of the 'Peach State' are you in? I spent some time in Valdosta back in the 60s. Beautiful country, for sure.
