I think 70-80A ought to be fine.

Here are my hypothetical speeds with a 24" tire running the motor at 2845 RPM
liveforphysics said:1st gear doesn't have to be useless on the 3spd. You set it up to have as much or as little torque as you require. For off road technical stuff, I find myself all the time in 1st gear just to give me a fine precision to creep with that is un-lugable. This is on a 212lbs dirtbike with 73bhp. 2nd and 3rd gear have the power to blow the tire traction or launch into a wheelie at any instant, yet I'm still rolling in first for the improved control the very short gear provides. You might find that true for technical off road stuff with your electric bike too, though I don't know for sure. On the street I normally just start in 2nd with that bike, and I'm sure you could start in 2nd just fine on the street for your bike too. But when you need that creeping up the side of a cliff on a twist mountain road control, having the granny first will be nice.
IMO- Gary's hub hasn't busted in part because it's a 3spd. Having 3 speeds means each set of gears can actaully be pretty large and strong. Getting a bunch of gears in there means each gear gets a lot smaller and more wimpy.
All of these hubs also take a disk. (but there are more...)
Shimano Nexus INTER-3________________186% gear range, first is useless, so its a 2 speed
Shimano ALFINE______________________Not suitable (cost)
Sturmey Archer 8 Speed XRK8___________305% gear range and $150, most say unreliable
Rohloff Speedhub_____________________Not suitable (extreme gear range of 526%)

methods said:Not until after Garry gets done testing all the hubs for me :wink:
I will go start a thread somewhere else titled "Patrick's burning issues"

Thanks Garry!

I ordered mine directly from Cyclone. Shipping is a bitch, but it is very fast. I got mine in three days.
