Nuvinci is running a special on the CVT developer kits, $150 for a hub and shift system!

John in CR said:So the developer kit only does some kind of pre-programmed auto shifting or can you still shift manually?

Mine has 13/14 double butted spokes (the same set-up was used by Cycle9 on their Cargo bikes) and IIRC 13G is the largest that will fit normally, but unless you plan on putting more power to the wheel than the RPM, Torque or HP max allow, I think you're fine with 13G, but I would recommend the 13/14 Double butted because they handle stresses of extra weight better than the straight spokes since broken spokes are often the product of lack of flexibility of the spokes breaking near the hub flange.
I originally wanted to put 12G spokes on mine, and was dissuaded by both Cycle9 and my wheel builder. Just my $ 0.02 :wink:

1000rpm input max means hubmotor input is a good choice

Thanks for the reply, LI-ghtcycle
FYI- if you have spokes that are 13ga. @ the bend, and 14ga. for the rest of the length, they are butted spokes..
..great choice for tandems, and ebikes.
The double butted spokes you mentioned (I made the same mistake once )
are thinner in the middle.
I knew what you meant, but just wanted to put a fine point on the butted/double butted spoke topic because it cost me ~50 bux to learn the hard way

Good luck!
