How was your holiday?
And I'm interested to see how the Bafang goes at 72v 28amps Knuckles turned his gears to peanut butter

You get the option of choosing which speed/rim size hub you want, right?
Also, if you're still thinking about the 10Ah Headway cells, there appears to be some quality control issues and overall badness (not sure about Getadirtbike's as they are different cells).
Mark_A_W wrote:Yes, Getadirtbike's packs are headway cells.
No, mine hasn't arrived yet.
The group buy reads like a total disaster area to me....

I get about 24-26 mph up most hills, 18-22 mph(depending on length of the hill) up the larger 10-11% grades with pedalling. I just got some torque arms and but I havent installed them yet. I have an 11t high gear that lets me pedal at top speed.

Cheers, I was hoping they'd start to firm up fast at the end. I'll have another go at lacing it up tonight after I pick up some #6 nipple washers and use knuckles lacing suggestions. Maybe http://veloplug.com/ are the trick?
What do you think of battery placements?

You won't need to adjust the CA wheel diameter, at least for this test, it's close enough to a standard 26" wheel+tyre. My CA read the same as my other speedo with the default settings.
