What I found very cool on the crossbreak style of pedal assist to the mid drive was the pedal assist went to the FW on the left side of the motor shaft. 2 things cool about this was .......
1-no stress on this free wheel as it was only taking the pedal assist duties of the human power assist before it added to the motors power.
2-the second really cool thing with this cross break style design is you were giving your self super tall gearing with smaller sprockets going in on the left side with the short chain etc. It does work so well with the only down side being that if its geared so you can keep up a nice cadence on the pedal assist for the faster end of the motors input you do end up with a slightly taller than idea for starting out at slow RPM's or putting along at low revs for trials style riding up hills.
I realize this type of pedal assist is not in the cards for the LR kit at this time but I wanted to mention this in case it may help in any design ideas you come up with for the ultimate way to work your pedal assist ideas into your system. I also realize for the high power folks out there the whole pedal assist is mostly a way to look like a bicycle and many don't really care about the pedal assist being super dialed in but I think there are many good reasons for having this part of the system working as good as it can.
