CVT Heavy duty transmission for motor bike?

[jawnn]

Has any one see a heavy duty ITV or some kind of transmission for a motor of about 2 to 4 hp on a 20" wheel?

about 665 foot pounds/sec?


I see people are working on the idea:

665 foot pounds is more torque than a cummins diesel...

well how about somehting that a motor cycle engin can produce?

chuck at endless shere gave me this number, and the math is way beyond me, so I have no idea what torque I will be using.


This is what I may have to use 12 24 48 Volt DC Motor Etek MT/Pattern Permanent Magnet at http://cgi.ebay.com/12-24-48-Volt-D...tem&pt=LH_DefaultDomain_0&hash=item3a5c255f9c

665 foot pounds is more torque than a cummins diesel...

power chart

I found this chart...I think it indicates that the torque is not more than 125lb/in.

So there must be some chance that an ITV or CTV would work... not that I would trust a V belt.

That torque is in INCH pounds. Divide by 12 to get foot-pounds... 165 inch pounds is a little less than 14 foot-pounds.
