Swagtron eb7 plus chain ring

[Dkershner]

I just purchased a Swagtron EB7 Elite Plus and am looking for guidance on what and where to buy the larger chain ring and different cassette for my bike. As it is I'm ghost peddling in every mode and every gear. I see a great post with pics of the parts and would like to one exactly where and what I need to buy so I can install them myself. Thanks,
