CH - The design allows for more positional changes than drop bars.

Why don't you take this to kickstarter and see if you can get some backing?

Wow well im fairly new to biking and to this forum and i love them both and i must say that is a wonderful idea.My bike weighs a ton now so whats a few more ponds?i just don't understand this weight thing.For me a Clyde the more weight i lug around the more i hope to lose also with my neck and shoulders problem always tighting up on me it would be wonderful to have the freedom to switch positions on the fly. Any way great job if i see one around and have the extra cash i will for sure give it a try.

I think part of the point of this is not that you absolutely must use flat bars, but that you can keep your preferred hand position through a range of torso angles. You like your bar-ends, but you can't brake or shift from those. Switch to this and North Road or similar bars and you can reach all your controls whether you're sitting upright or low in a headwind.

bike fitter version
 

In addition to a retail product, if you had a version with a built-in protractor (or digital readout) for the stem angle and perhaps an adjustable length, I could see that product being attractive for bike shops.

Good luck!

If nobody mentioned it yet, you might check with the CPSC to see what they require for product certification, especially if it can be used on children's bikes. Liability and consumer protection issues often over-ride design and manufacturing issues. Good luck.

Years ago I came up with a series of bicycle trailers but never got to the manufacturing point. Manufacturing cost was one factor, ability to defend the product from competing companies was another big factor and my pockets weren't deep enough to pursue it.
