Greetings, and why does this product not exist?

The frame shape of the Sunbeam and Ace model from Hawk: http://www.hawkclassic.com/#
is on the right track= plenty space for engine so it sits low on the frame.
And space to place a 3 speed hub transmission just behind the engine and a Jackdrive with 3 sprockets. One is a freewheel conected via chain to the pedal's crank. The second is fixed and conects to the engine. The third one conects to the rear wheel sprocket(also fixed, for clutch start). All sprockets selected so that the right ratio is achieved at the rear wheel, with a max speed of 40mph, but with good pulling power and acceleration from the low geraring to start.
 
Heres a thought, why don't we all form a company and invest, become incorporated, build bikes that we decide are the cheapest and the best for the cost then sell with a complete liability release with each one that goes out the door.

adding to my previous thread and answering Dockspa1

It is an idea Doc. There could/should? be more than one option:
To begin, the cheapest alternative; and options for higher end versions with more performance or/and final intended use not achieved with the the basic model.
But the key again I want to put emphasis on the modular concept. Upgradable from the base model. So you can reach whatever level your needs/hobby/mind takes you. And it could be addictive in a good way. A hobby.

To finnish my previous thread:
One detail that I forgot to mention:
The Jackshaft actually consists of a Sram Dual drive with disc brake mounting holes.
The sprocket(3rd on previous thread) conecting via chain to the rear wheel goes mounted where the disc would go. The other two (one sprocket conecting to the engine and the other sprocket conecting to the pedalcrank) would mount on to this internal hub on the cassette side, but with the freewheel canceled on the one conecting to the engine. There is some work there, but would yield 188% change from low to high gear.
Another option would be to use the new "Sram I-Motion 9 disc brake" rear hub with 340% variation from low to high gear, instead of the 3 speed (188%). Again modification on the freewheel side has to be made so engine can be started by releasing the clutch, but with sprocket conected to pedals still able to freewheel. I think Staton sales something like that for the rear hub. http://www.staton-inc.com/Details.asp?ProductID=3244
One of the reason forhosing Sram: http://archive.mtbr.com/17/0EF79283.php is efficiency vs. other. I think is well build. It is not Rollhoff, but for what they cost I think you get enough reliability and ratio range. One last option would be to use the NuVinci(I don't know reliability, but no bad news so far sounds good); Staton sales it. I don't know if it has disc brake capabilities though to mount the output sprocket to the wheel via chain.
