A Giant Boulder aluminum frame
It's a Goldden Motor front 500w 36v kit that came with the 36v 12Ah SLA pack. I've since gone to 48V 12Ah SLA but 40lbs of weight on the rear rack wasn't making me nor my panniers happy. Made a picture to justify to me the benefits of switching to lithium.
I've collected a couple laptop batteries and made a pack with em. Soldered a bunch of Deans Pro tabs to the 2 packs on the right and the rainbow colored one I made with cells of similar voltage and soldered 12ga wire across 4 pairs to give me 20Ah using pairs of 2500mAh batteries. So the picture shows 3 packs of 18V 20Ah 5s4P.
My cheap hobbyking charger peaks them at 20.5v each so it's a 61.5v pack at 20Ah(more like ~10ish realistically)
This is how I use it now. With the Li-Ion pack I can do 20MPH(32kph) without trying and I've topped it out at 34MPH(54.7kph) downhill(phone gps)
Hope I didn't leave anything out. Hope you enjoy.
