Need help with Giant Sedona DX and EBO Phantom kit purchase

[CMilly]

I recently purchased a Giant Sedona DX 2016 hybrid bicycle from my local cycle store. The bike has a SRAM PG-820 11x32, 8-speed cassette on it, as well as Shimano EF51 shifters, Shimano Altus front and rear derailleurs, and a Shimano M131, 28/38/48 crankset. I was looking at the EBO Phantom http://www.electricbikeoutfitters.com/ebo-phantom.aspx
I was wondering if the 8-Speed rear wheel hub options would work with my bike's setup. Does EBO send me a freewheel that will function even though I have a SRAM cassette and Shimano shifters? Or should i select a "No freewheel required" option and reuse my PG-820 cassette?
Once I install the kit will my gear shifts still be suitable and healthy for the bike, or should i take it in to a shopp and get the shifter cables adjusted? Thanks.

Just looked up both bike and kit, the ebo kit should come with a freewheel that will fit the components you have. if not you can take the freewheel cassette of the giant wheel and put it on the ebo kit as long as there the same diameter threading..then you might have to have your derailleur adjusted but probably will work just peachy kean.
