You may have covered this, but why didn't you add a freewheel to the rear sprocket?
I had two because the first drive chain loop setup covered both motors.
There's no space or a feasible way to add a freewheel AT the rear wheel. So the freewheel has to be on the motor.
Freewheels gain me an increase in range (through coasting) comparable to what I would receive by having regenerative braking, but without the cost of having a more sophisticated controller.

The solution I've come up with to mechanically link the two motors is to buy two small #35 sprockets, then drill and tap their bores to match the thread on the end of the drive shafts.
I will then have to make adjustments to the motor mount plate to update their spacing to be in line with each other and the rear wheel.
