Yeah baby, I bet it climbs like a goat eh? And retains some top speed. Best of both worlds.
Good thing you have it running on a fairly big battery. What do you see on the CA climbing? 4000w? Or do the motors climb so good you only see 2500?
I was wanting to try dual motor with a fairly fast rear dd motor, and a slow wind gearmotor up front. Never got around to it, especially after getting a nice 5304. It needs no help on the hills. The idea was if the rear motor started to stall up a hill, you'd flip a switch and power up the gearmotor to help.
Bummer about the dogs. Sounds like a relief that the human left though. At least getting new good dogs is easy.

Btw how does the controllers fare with being enclosed?

Trust me, Ben's description does not do the hill in question justice. I had the pleasure of spending some time with Ben when the Taiwan Bike Show was on, and let me tell you, that is no ordinary hill leading up to Ben's rather nice pad on the hill. It is frankly kind of scary to go up it, as you are scared the bike will flip or go down for fear of the brakes not stopping you, or going over the bars. Get a movie up dude.
I've been threatening to make some plastic enclosures for my triangle packs forever, seeing your handy work has pushed that idea back on the front burner. I'll have to get over to Taiwan again sometime soon when things are quieter. Taiwan is cool, kind of like China but with better manners, except the scooter riders, those guys are crazy....

I really like this idea, might try to incorporate it myself. For the cylinder fastened to the bike frame, did you simply thread the frame material? or is there more than meets the eye?

I see you bought one of those ebay battery tab welders... is it any good ?
I've got most of the stuff to build my own from designs on the net, but I'm tempted to get one of those ebay ones to save myself some time
how did you like the cell holders ? I was going to buy some of those too, but I've got a 3D printer on the way so I'm thinking I could just print myself some instead
