Well I did a speed test, on a flat hard packed gravel road I was able to hit 54km/h (33.5mph) on the MTB under my own stength, not bad. My brother can hit 50km/h (31mph) So when electric he definitely wants to be able to hit at least 45km/h, and with pedal assist, 50km/h I'm sure.

I think I am going to stick with a 14s pack, as that allows using a balance charger like the 720i I already have. He wants to sell me on a BMS, but I don't feel it's necessary at all. I might as well get a 8s pack for my lawn mower to save on shipping as I was going to get some of these for it sooner or later.

I can't believe how economical these cells are, they have the power, the A123 toughest we have come to expect, the cycle life, and best of all they are now energy dense as lipo. $0.75/Wh Is cheap as chips once you think how long they last.
