Eliminating the driven sprocket

Andrew,
The front freewheel is not a problem, we found a source. As for the rear derailluer, I think a standard one will live if you don't abuse it. You can use a standard casset, an internal or a NuVinci. Either way you still need the front freewheel.

HI Ghost,

I have no idea what a front freewheel system would run but.... if you use the Nuvinci (or possibly another internal geared hub with minor modification) you can run WITHOUT the need for the front freewheel system....I think Staton makes a dual freewheel sprocket for the rear where by the rider pedals on one freewheel and the engine sprocket drives the other freewheel....sinve both sprockets are freewheels (single speed units) the engine can power the bike without turning the pedals YET both the rider and the engine can benefit from the gearing offered by the internal gearing hub (engine starting is not a problem either)....That is the way I would have gone to obtain gearing BUT I didn't have a good Jackshaft system figured out (appears you have a good one tough!)...

The above is just a thought....I'd LOVE to see multiple speed gearing no matter how we get it!!....I have a certain scooter I'd love in mind I'd love to smoke! HA ;-)

Andrew

Wow - I never heard of such a thing. I can't exactly get my head around it.....how could this work? I'm not saying it wouldn't work I just can't picture it.

One chain, right?

Almost forgot. Our BOM is complete, some few logistics to work out, we have a domain name for our website. Need to place an expensive order with a supplier. As I mentioned, board meeting this coming weekend.

Now a double freewheel on a Nuvinci or any internal hub gets the mind to rethinking everything again.
Cant wait is all I have to say. One thing on the 200 is that everything to convert to the jackshaft?

Yes that comes with everything, cranks, freewheel, spindle, sprockets, jackshaft, bearings, mounting hardware etc.

Well let me ask you this are you going to sell just the jackshaft kit? I really what to try it on this schwinn FF crank.

Ya, how fast does that go?

That's a real possibility. Sure, why not. We did a lot of research today and we changed my bike over. We have a few NEW issues to work out but nothing major. But the thing may be - is the Schwinn FF a two gear deal?

Good question. On my bike it went like a raped ape with a turbocharged afterburner. But the low end was not quite right - we need to figure out the the next matching driven left sprocket....more ordering....

Ghost0 has photos and will be heading for home......

We had a good hill ride and a lunch. Lots of fun wrenching. Board meeting adjourned.

More later.........
