A big part of getting this all working was appreciation of how its supposed to work. There were no instructions or atleast none which explained anything to an ordinary human being such as myself. Through trial and error I'd get there but there was quite a bit of time spent figuring out how and why it did not work. It's worth noting here for those of us who aren't familiar with this setup how it works. The kit comes with spot magnets. The magnetic field they generate is how the motor knows to work. By this I mean once they are in play (your brakes are not on/applied) then the motor will happily assist you. As soon as you pull a brake lever the magnetic field flux lines are far enough away from the sensor for it to say, rider must be braking so I am going to turn off the motor. This is the really simple but important facet of how this all works to grasp. It took me a while to figure it out without the missing manual.
