what are the torque in footpounds for the 408 and 5305?
 
what i am looking for is the torque. in foot pounds.

i have no idea what those numbers mean you linked to.

There used to be similar info for 530x on the crystalyte website but it seems to be gone.
 
ok then what is the torque specs for the 5305?

Correct me if I'm wrong, but the simulator at ebikes.ca calculates newton meters for the motors they sell.
My set-up for instance looks like it puts out ~96 Nm with 18Ah of NiMH and 50 Amp controller. At 35A, 80Nm.

With 66 volts of Dewalt A123 it's 120 Nm.
With that battery pack, 50 Amp controller, the Xlyte 408 is 90 Newton Meters or 60 pounds of thrust.

The explanations are in the notes.
 
has anyone took a torque wrench ( looks like a ratchet handle but has a torque needle on it. and tried to measure one?

The data is mysteriously gone from the crystalyte site but I bet someone here has it, and I bet it can be found on some other sites.

there is a button to select Torque in Pounds or Newtom meters. it defaults to N-M.

a 40X can have from 25 pounds, all the way to 80 depending on the model, amperage, and voltage.
a 530X runs from 27 to 105lbs

Compare that to my 50cc Peugeot that makes an amazing 30lbs of torque at the rear wheel.
 
The problem with a torque wrench idea is the motor probably does it peak torque at just over a stall. This is my experience. It seems like the phases large enough (1/8 of a wheel turn) and the controller usually won't let you hold a stall it would be really cool to have true dyno.
