Anyway to achieve these specs for less than 1000 dollars?

Ok kit, similar to Yescom eBay DD's.

Battery - I would go for the INR18650-25R 14.7Ah triangle battery pack with bag. The 20R 11.4Ah might do it depending on how slow you ride for 15 miles range but the 14.7Ah should pretty much cover that distance and then some. Those packs have the best C rating and enough capacity to deliver a sore butt. I'm a fan of frame triangle battery pack mounting. Excellent weight distribution.

Unless building it yourself is the point, why not go for this?
https://www.indiegogo.com/projects/wave-electric-28mph-bike

It says it'll handle riders up to 300# and one of the guys running it has been responsive to discussions on the forum at electricbikereview.com Answered these questions for me:

Any thoughts on V brakes having sufficient stopping power for 350 pounds (the rated max 300# rider plus 50# bike) at 28mph?
"Good stuff, Matthew. I have had a couple people just under 300 pounds (I have some big friends I guess) ride the bike up to about 26 mph, but I never asked them to slam on the brakes, but they were riding along the beach and had to slow down for groups of cyclists in front of them and they had no problem slowing down. You bring up a good point though that the V brakes aren't necessarily designed to perform well enough to brake super hard and come to an abrupt stop when going max speed (26-28mph) and with that much momentum of someone 300-350 lbs. I would definitely get a feel for the bike before blasting around the city at top speed!"

Is the throttle variable or just on/off?
"The throttle is definitely variable (on/off throttles are awful and I don't know why any company even manufactures such a thing)."

With shipping, that's going to cost more than a buck per wh and eat up most of your budget. An rc lipo pack cost a third of that, will last just as long if not longer, have no sag by comparison, and can be easily serviced if there's a problem. Look up the specs on google for the icr18650 22p samsung battery and understand what you are buying. Look at cycle life. 70% capacity after 300 cycles at low c rate discharge.

Building it myself was not the ultimate point, no. I was literally about to purchase this the moment after I clicked your link. 28mph with a fantastic range + warranty + nice looking frame for 500 bucks is incredible. But it doesn't ship until July -_- I was hoping to have something within the next several weeks. I'm gonna email this guy and tell him that I'll donate an additional 150 bucks if I can get it sooner, because that's pretty incredible.

48v 1865 good luck

On that indiegogo, read the first few pages see what that means for a chinese ebike http://endless-sphere.com/forums/viewtopic.php?f=31&t=66220 It doesn't have gears and is sourced by "PhD marketing geniuses," not bike guys. It may or may not ride ok when the electrics die..

My opinion is typical, can't go wrong with a Paul battery. That 22p looks like $730 shipped to maine. The cheap DD kits linked above come in at under $300, so there's your $1k, shipped.

I went the opposite way. Beefed up geared motor kit from a US vendor. Cheap Panasonic 18650/11ah dolphin kept the total under $1k shipped. Battery has a hard case w/more mount & lock options. I'll ride it for a while, if i need more capacity can save for a bigger/stronger battery later. Keep the Panasonic for backup or trail rides.

You don't say what kind of bike, hills, pedal input you can do. DD may or may not work depending on how big your hills are... good luck..

thanks dude. It's all flat terrain where I live

So now I'm wondering. Would I be better off to buy that kit off amazon and the samsung battery from em3v for a total of 1000? Or should I spend an additional 400 and just buy this complete kit from ebikekit.com ? http://www.ebikekit.com/electric-bike-conversion-kits/e-bikekits-lithium-48-volt-battery-pack/1000w-geared-motor-with-48v-lithium-battery-12-26-miles/rear-500w-geared-motor-with-48v-10ah-lithium-battery/
