Re: pic: 6 speed?? Great in theory - lets see how it works!

Part of that involves using sufficiently robust gears, since a partially engaged gear does not evenly apply its load to the entire face width!
The design intent is shift-on-the-fly capability. How well it works will remain to be seen. We plan on auto shifting - requiring a driver to also manage which gear he/she is in is not something we want to do.

We would like our shifting mechanism to be fast AND accurate enough to engage the vast majoirty of the gear even in the heat of battle. Double-edged sword whether to go with wider or narrower gears. Wider gears mean more strength but also mean more travel to fully engage and more weight. Narrower gears are lighter and quicker to engage but may not have the necessary strength. Time to add some math to the design mix.
