I want to build an e-bike. I have 3 design ideas, and would like some feedback on which might be best first project to tackle.
1. 29" MTB with disc brakes and front fork. I have this bike. I would like to make it be able to cruise 20-25mph or so, along lake road for 3 miles, then climb this https://www.strava.com/segments/8999521?filter=overall 2.7 miles, 932 elevation gain, 6% average grade, though it gets to 15% in spots. I currently pedal this climb in a 30X36 gear. I weigh 175 lbs. I am going to pedal, I just want it to go faster. Would an ebay 48v 1000w wheel kit, $200 and 48v 15ah li-ion triangle shaped battery do this climb? Should I get a leaf bike 48v 1500w?, $340 This bike has a ton of room in the front triangle. What hub/battery combo do you think would tackle this once? twice? I am open to buying hub, controller, battery separate. There is one side of me that says just keep you're first build easy and get a dillenger kit. There's another side of me that thinks a bafang middrive BBS-02 is the way to go.
I would like to keep the kit as light as possible, and the bike as efficient as possible. Ideally, I'd like the battery and controller all contained in the front triangle of the bike. Battery, hub, controller, I'd all like to keep as small and light as possible. I am moderated by desire to keep first project affordable, easy to build and maintain battery. I understand lipo is lighter, higer performance, but more finicky, and to some degree think that a li-ion set up makes more sense for first build. I am torn between cheapy ebay 48v 1000w, golden leaf 48v x 1500w and bafang middrive, with 48v x 20ah triangle li ion http://www.aliexpress.com/item-img/Free-bag-Ebike-Battery-48v-20Ah-1000W-Electric-Bike-Battery-48V-with-2A-Charger-BMS-Lithium/32462744501.html?spm=2114.10010108.100005.10.lyzU8G# or lunacycle.
2. Iron Horse Kumicho DH bike. http://s1206.photobucket.com/user/ooklathemoc/media/2012-10-25171701.jpg.html Buddy is asking $300, think I can get it cheaper. I'd want to do the same climb as before, but more power, less concerned about light weight. I'd like to keep the batterys in the front triangle; some in cavity between tt and dt in front of the shock, and some to the side of dt/tt. I don't wan't to get too crazt with battery building... ideally like something where I pair 4 batteries together relatively simply. This bike would be less about pedalling, more throttle. Thinking 1500w hub and lipo.

I would want lipo batteries, in the cavity of the front triangle of the frame, in front of the shock, as well as to the side of the down tube/top tube, starting where the shock is. I'd plan to fill in the "tank" with styrofoam and ducktape.
3. Novara touring bike with Qute Q100 geared hub, lightweight, minimalistic build. The bike is 26lb touring bike, with triple and canti brakes. I'd like to have battery/controller all in rack bag, discretely hidden. I'd like this bike to be pedal elec, no throttle. https://bmsbattery.com/ebike-kit/426-q100-36v250w-350w-rear-e-bike-kit-with-led-meter-ebike-kit.html
