In this video I glue one of the spot magnets onto the brake lever so that it can provide the flux line sensor with the info it needs to cut the motor when the rider applies the brake. It's imperative that the spot magnet is glued properly and in the right location for this to work but also in such away that it does not fall off. Add to that, it's vital that th epoxy does not glue the brake lever permanently or we'd have a whole slew of new problems in having this thing behave like a functional bicycle.
