They make you purchase a free wheel sprocket so use a cluster of em with old school derailer. Could have the bull gear from H#%$ or over drive ,and win the Darwin Awards! Heck looks like there is room for it if you already have a derailer around probably cost the same to buy? NuVinci hubs meant to say don't how to edit that. Well can probably get 3 or 4 sprockets in there? Dan help me on this one!?! snork!

The Nuvinci has a pretty wide range already. If you should ever feel the need for more you could always use a dual sprocket freewheel like this one at the bottom of the page. DOS Freewheel you wouldn't even need a deraileur.

While we're talking about the NuVinci, I noticed they will be selling a "developers kit" for light electric vehicles for $600. Has the regular hub, plus an electronic shift controller - which means an "auto" trans and wouldn't get the authorities so uppity. Thought it would be a cool idea for a bike...

Awesome idea Goat Herder! With a reducing jack shaft, 2 chains (like some electrics) and freewheeling cranks,would be an internal shift. Just woke thinking about your idea. Could easily be done and would work great. Would need a chain guard (round, flat plastic sheet) between the largest rear bike sprocket to isolate the engine chain but would work.
This could be a winner!

with an electric 30% would be an incredible loss. With gearing on a ICE would it be as great a concern? And not worth the return...
Asking

Since my motor of choice is 1.6HP I would be losing a third.....down to about one horse.
Fairly significant.
This is presuming, of course, the Ebike guy on that link has it right at 30% loss.
Comprehensive dyno test would be the only true evaluative measure, but that's why I asked.
Aside from the cost, which comparatively speaking is more than something like the Nexus but far less than the Rohloff, there is the weight factor.
For me, this is a real trade off on the NuVinci coming in at around 9 lbs. | | Thread Tools | | | | Display Modes |  Linear Mode |
