Apparent Warranty issues with Davinci N380 and 750W motors?

[BikeMike]

I just bought a 750W Evelo Aurora yesterday. I read the NuVincini manual. I found 250W and 500W, but no 750W specifications. I called Evelo and left a message. I wonder if the 750W is too powerful for the NuVinci N380?

I read several posts where people had problems with NuVinci hubs. I am not sure how reliable the hubs actually are. If i had a problem, i want the option to install a derailleur. The Aurora does not seem to have a dropout that can accept a derailleur.

I think I should change my order to the Delta X. I cannot tell from the picture whether the Delta X has a derailleur hanger, because that area is all colored black. I do not see a derailleur hanger, so i assume the Delta X does not have a derailleur hanger.

Is the N380 hub warrantied by Fallbrook?

• I do not see 750W covered by this warranty.
• I also believe the gear ratio is outside of 2.0 to 1.
• I also believe the BBS02 has 95NM of torque.
