olemetry wrote:Thanks guy. Now that I look a little closer, I think I see what you are saying. You recommend 8T just because of my intention to run 12s correct? Cellman gives a warning of 48V on 6T, but gives a warning of 60V on 8T. I do want another Golden Motor like the 20" molded wheel you have, but that will have to wait for a differnt build. I also want to freewheel with the Rockhopper, putting the controller in batteries like you have in a bag and then just unplug it and remove it to ride the bike regularly.
I assume that the 8T does not come with a 7-speed attached and yall kinda went back and forth in the thread about which one is a good one. Can you recommend who I should get the 7-speed from? What about the torque arms - I dont think I have anyone around here than can custom make them.
Also, what do you think the shipping is approx. from cell_man to New Orleans? I sent him a letter, but as you know it takes a while. Thanks again man. You do us all a great service!

Yes, i do. If i shift while hitting a bump, i'm screwed.
However, a front derailleur is both useless and doesn't jive with a frame bag too well.
I'm sure there's a better solution.
Scorpion: yes, i love having it back in action! But i feel like it's so slow now, in comparison to the 20" pie on 6kW..

That's totally true. That's the direction my builds are heading in. I think it happens to everyone who really dives into this. The end of this downward spiral is building something like liveforphysics puts together.
I started out in a 250w cell_man MXUS geared motor kit. Now i am pushing 7000w into a magic pie and 2500w peaks into a MAC. I am ordering an eTek ( motenergy ) 22lb motor and am going to run it chain driven on a hardtail or maybe a xtracycle style configuration.
Pray to your selected diety that you are not afflicted this bad
