what I was trying to say is you can build a drive train with two motors driving one shaft (or wheel) that is not self shifting
and to turn it into a self shifting two speed system, all you have to add is one moving part - the spring loaded tab that locks into the gear in one direction only.
This is not complex - its extreemly simple. Get you hands on the back wheel from a ten speed bike and take the rear gear cluster off (all the bearings will fall out - use a junk wheel)
You dont want to do this without the one way clutch - spinning a motor past its top speed, loaded, connected or otherwise, is still a huge drag on the driving motor.
and besides, motors have a physical top speed - if you spin them any faster the centrifical force rips it apart.
