So many options, which kit to go with?
There are so many different options to choose from it's kind of difficult to pick the right one.
Here is one that has caught my eye: it's a front hub, 20mph, 20-30 mile range for $360
https://ampedbikes.com/whatsincluded.html
along with the 36V 10 AH Phylion Battery pack for $350
https://ampedbikes.com/buynow.html
So that's a little over $700. I already have a really nice bike I would like to put this on. Any advice?

Their Ampedbikes kit look nice and honest. As for the 36v 10aH lithium battery, you may be able to get 20 miles range @ 7-10 mph using throttle only. The realistic figure is typically less due to stop signs, red lights, traffic, and hilly areas. I live in San Francisco & commute from one city to another with SLA, Nimh, LifePO4 (both Dewalt's A123 & Chinese made type), Lithium. Lithium battery at 10aH is a little stress when you go 20mph with it due to typical discharge rate unless you know the exact C rating of 5-10c which the A123 provides). Make sure your really nice like has got 135mm at least for the front and/or the rear drop out width. In addition, you should understand any hub motors (except the ones with internal gears + freewheel built-in) will drag & increase rolling resistance if you glide on the road & the consequence is simply reduce mileage. Lastly, spinning a massive weight of the hub motor along the wheel takes more energy. It's kind of like attaching 4 to 5 1 liter of soda on your wheel and you try to spin along with it. Just my 2 cents.

Thanks for the information.
Do you think I should go with a 48V20ah battery over the 36V10ah battery?
If so, where can I get the best deal on the 48V20ah battery? Also, do they make 48V10ah batteries?

You will naturally use your ebike less if your carry a 48v 20aH of battery event for a typical LifePO4 one weights 25 pounds. Your mind will automatically convince you to get something lighter & lighter in a long run. Believe me on that. As for best deal, it better be on eBay. However, finding an honest seller would be another challenge on top of shipping from another country.
