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.
