... provides seamless CVT-style shifting. Seen here:

Just wonder whether tech might be of interest to folks riding with Bettery-Electric assist...

very unconventional approach to what is relatively straight-forward with planetary gearing systems (both in the crankset and in the rear). CVT in the rear already with Nuvinci, and for the front there are a few CVT designs coming down the pipeline from known manufacturers. Not sure I would trust this type of design over the more "internal" options, which are certainly more durable and reliable.

I'm looking for a partner or a buyer (company) for this product.
Patent has been filed.

Interesting, But ...

Shimano , and , Sram

are now using 1 x 11 gearing, more and more bikes now have just a Single Chainring on the front and 11 speed cassette on the Rear.

I would stick with the improvements that Shimano and Sram are doing.

Until ...

Shimano , Sram, etc, starting making a much better version of that,

I am thinking that needs to be done better, like put 11 or more gear ratio's on the ... inside of the Bottom Bracket

Yea I am talking BB 130 or BB 200 or BB 240 Bottom Bracket Shells ! ( and you thought a BB30 was big , just wait )
You would also then get Ultimate Stiffness at the BB area !

You would also then get Ultimate Stiffness at the BB area !

There's an app for that.

Stiffness in the BB area ( Bottom Bracket Area ) is what designers of performance bikes have been improving on for years now.

The stronger/stiffer the BB area the more power that is transferred to the road, which means faster speeds and more millage covered per amount of energy ( watts ) a rider puts through the BB /Crank area.

Look at the Modern Carbon Race bikes, see how much material is down there, now picture that area even bigger, with enough space inside to run some gearing, not cogs like you have on your rear wheel, rather
a small gearbox . with electronic Di2 shifting . that way you can have a rear hub motor with only one gear = less weight , and one or two chain rings up front, to give as much gearing ratio's as you have now on a modern bike.

There would also be less weight on the rear wheel = less rotating mass. This would be a Godsend to all the full suspension bike riders . and Helpful for everyone.

I remember something like this from the 1980s. It was torque based. the harder you pedaled, the more the gear arms retracted, giving you a lower gear ratio.
