Watt-hours per mile:
No idea since I can't use the Doc Wattson anymore, but I'd venture a guess of around 20-25.
I'm too lazy to redo all the documentation I put on the Endless-Sphere here:
A few pics!
The BD36 after it's been ground smooth, sanded, and clear-coated.
The new 72V battery block (soon to be replaced with lithium).
The modified controller innards.
And the bike.
And a video of the wheel spinning up (how do I embed this...?):
It's like 90+ degrees around here lately WTF do I want a heater for?
It's a hub motor. The drivetrain is non-existant. :p
Modified Yi-Yun YK-42 (I think) with 4110 FETs
Pair of random SLA chargers.
Random four (4.5Ah) pulled from my skateboards and two 5Ah PowerSonics. I can get all of about 1.5-2Ah out of them.
30lbs sounds about right.
Conversion time and cost:
Like $300 and too much time.
