BMC 600w "torque" version vs. "speed"

[dscline]

Hello,
I'm interested in adding some lightweight power to my bike, and the 600w BMC seems to be a great choice if you're looking for hill climbing torque. I've seen some top speed estimates for the 'speed' version, and I've seen the claims that the torque version has better low speed torque at the expense of top speed, but I haven't been able to find anything that quantifies that trade-off. Does anyone know what the top end would be for the "torque" version @ 48v on a 700c wheel?

Thanks!

Thanks! I saw that page, but somehow missed the speed reference in the "T" version. So is it fair to extrapolate from their estimated 36MPH @ 72v that it should do 24MPH @ 48v? Should I assume their rating is with a 26" wheel? I assume it's too soon to tell how durable these would be at voltages over 48v, and amperages over 20a?

I saw the Cycle9 test and from what I remember, there was very little difference between the torque version and the speed version. If you want hill climbing ability, I'd either go with a 5305 or an Ezee.

How do you conclude from that test that the 5305 or Ezee has more torque?
