Just a thought Nuvinchi hubs

Both bikes use a Sick Bike Parts shift kit.

Would it not stand to reason then that the higher top speed you mentioned with
the NuVinci is simply because of the higher overall gear ratio of the internal hub over
the traditional cog set?

I think it's more of having the "right" gear with the NuVinci. 6th and 7th gear on a derailer bike are pretty much unusable with most of these motors - there's simply not enough power to keep going faster. Now if you have a nuvinci, you can get a slightly different ratio and eek out that little extra speed that there is still power for.

I think Jason has it right. both transmissions have room on the top end but being infinitely variable the Nuvinci allows you to fine tune the sweet spot.

Sounds Like An Accurate Statement To Me. Jm2cents.
